Choosing a biochemical analyzer is an important decision for hospitals, diagnostic laboratories, clinics, medical centers, and laboratory equipment distributors. The right analyzer should match the laboratory’s workload, required tests, available space, staffing, budget, and long-term operating needs.

Many buyers start with a simple question:

How much does a biochemical analyzer cost?

However, price should not be the only consideration. A low-cost analyzer may not provide the required test menu or throughput, while a high-capacity system may be unnecessary for a small laboratory.

A more practical approach is to evaluate the complete laboratory workflow.

Important factors include:

• Test menu
• Throughput
• Automation level
• Sample volume
• Reagent system
• Reaction system
• Optical system
• Calibration
• Quality control
• STAT testing
• LIS connectivity
• Maintenance
• Technical support
• Reagent cost
• Consumable cost
• Total cost of ownership

This guide explains these factors in simple terms and provides a practical framework for selecting a clinical chemistry analyzer.

What Is a Biochemical Analyzer?

A biochemical analyzer, also called a biochemistry analyzer, clinical chemistry analyzer, or chemistry analyzer, is laboratory equipment used to measure chemical substances in biological samples.

Depending on the model and reagent applications, common tests include:

• Glucose
• Urea
• Creatinine
• Uric acid
• Cholesterol
• Triglycerides
• HDL
• LDL
• ALT
• AST
• ALP
• Bilirubin
• Albumin
• Total protein
• Calcium
• Phosphorus
• Amylase

Biochemical analyzers are used in:

• Hospitals
• Diagnostic laboratories
• Clinics
• Medical centers
• Private laboratories
• Research laboratories
• Laboratory networks

Different laboratories require different analyzer configurations.

Why Is Choosing the Right Biochemical Analyzer Important?

A laboratory analyzer is not simply a piece of equipment. It becomes part of the laboratory’s daily workflow.

The wrong configuration can result in:

• Unnecessary equipment costs
• Insufficient throughput
• Limited test options
• Higher reagent expenses
• Difficult maintenance
• Workflow delays
• Poor integration with existing laboratory systems

The right analyzer can help a laboratory organize routine biochemical testing according to its workload and operational requirements.

Therefore, purchasing decisions should begin with the laboratory’s needs rather than the equipment’s marketing description.

Step 1: Determine Your Daily Sample Volume

One of the first questions to answer is:

How many samples does your laboratory process every day?

For example:

• Small clinic: relatively low sample volume
• Small laboratory: low to moderate volume
• Medium laboratory: moderate volume
• Central laboratory: high volume

The actual workload should be calculated using both samples and tests.

For example:

200 samples/day × 5 tests/sample = approximately 1,000 tests/day

This is more useful than looking only at the number of samples.

What Is Biochemical Analyzer Throughput?

Throughput describes how much testing an analyzer can process during a specific period.

Manufacturers may express throughput as:

• Tests per hour
• Samples per hour
• Tests per day

For example, an analyzer may be described as having a throughput of a certain number of tests per hour.

However, buyers should ask exactly how the manufacturer defines the stated throughput.

Actual laboratory performance can depend on:

• Test mix
• Sample preparation
• Reagent loading
• Calibration
• Quality control
• Reruns
• Dilutions
• STAT samples
• Operator workflow

Therefore, advertised throughput should be compared with the laboratory’s real workflow.

How Much Throughput Do You Need?

There is no universal throughput requirement.

A simple planning approach is:

Daily testing volume ÷ Available operating hours = Approximate hourly workload

For example, if a laboratory needs to process 1,000 tests during an 8-hour working period:

1,000 ÷ 8 = 125 tests/hour

The laboratory should then consider peak workloads, urgent samples, reruns, calibration, QC, and downtime.

This means the required analyzer capacity may be higher than the basic average.

High-Throughput vs Low-Throughput Biochemical Analyzer

Low-Throughput Analyzer

A lower-throughput analyzer may be suitable for:

• Small clinics
• Small laboratories
• Medical centers
• Low-volume diagnostic facilities

Important features may include:

• Compact size
• Simple operation
• Flexible test selection
• Lower sample requirements
• Easy maintenance

High-Throughput Analyzer

A high-throughput chemistry analyzer may be considered for:

• Large hospitals
• Central laboratories
• High-volume diagnostic laboratories
• Laboratory networks

Important features may include:

• Automated sample handling
• Large reagent capacity
• High testing speed
• Continuous operation
• STAT testing
• LIS connectivity

The key is to match throughput to actual workload.

Step 2: Define Your Required Test Menu

The test menu is one of the most important factors when selecting a biochemical analyzer.

Start by listing all tests currently performed by your laboratory.

For example:

Basic Chemistry

• Glucose
• Urea
• Creatinine
• Uric acid

Liver-Related Tests

• ALT
• AST
• ALP
• Bilirubin
• Albumin
• Total protein

Lipid Tests

• Cholesterol
• Triglycerides
• HDL
• LDL

Other Tests

• Calcium
• Phosphorus
• Magnesium
• Amylase

Then identify any tests you may add in the future.

Why Is the Test Menu Important?

An analyzer may have impressive technical specifications but still be unsuitable if it does not support your required assays.

For example:

Laboratory A needs:

• Glucose
• Urea
• Creatinine
• ALT
• AST
• Cholesterol

Laboratory B needs all of these plus:

• HDL
• LDL
• Calcium
• Phosphorus
• Magnesium
• Amylase

These laboratories may require different analyzer configurations.

Therefore, do not choose a biochemical analyzer only because it supports a large number of parameters.

Choose one that supports the parameters you actually need.

Step 3: Choose the Right Automation Level

Another major decision is:

Should you buy a semi-automatic or fully automatic biochemical analyzer?

Semi-Automatic Biochemistry Analyzer

A semi-automatic analyzer requires the operator to perform some testing steps manually.

It may be suitable for:

• Small laboratories
• Clinics
• Low-volume facilities
• Laboratories with limited automation requirements

Potential advantages include:

• Compact design
• Simple workflow
• Lower initial investment
• Flexible operation

Fully Automatic Biochemistry Analyzer

A fully automatic analyzer automates more testing procedures.

Depending on the model, it may automate:

• Sample pipetting
• Reagent dispensing
• Mixing
• Incubation
• Measurement
• Result calculation
• Washing
• Calibration
• Quality control functions

It may be suitable for:

• Hospitals
• Central laboratories
• High-volume diagnostic laboratories
• Facilities requiring greater automation

Semi-Automatic vs Fully Automatic

Factor	Semi-Automatic	Fully Automatic
Automation	Partial	High
Manual operation	More	Less
Throughput	Usually lower	Usually higher
Initial equipment cost	Often lower	Often higher
Sample handling	More manual	More automated
Laboratory size	Small to medium	Medium to large
Workflow	Operator-assisted	Automated
Maintenance	Generally simpler	More structured
LIS	Depends on model	Common on many systems

Neither type is automatically the correct choice.

The decision should be based on laboratory workload and workflow.

Step 4: Check Sample Volume

Sample volume is an important specification for a biochemical analyzer.

Different systems require different amounts of sample.

Ask the supplier about:

• Minimum sample volume
• Reaction volume
• Dead volume
• Sample probe volume
• Dilution requirements

A low sample volume can be useful in situations where sample availability is limited.

Relevant search terms include:

• low sample volume biochemical analyzer
• low volume chemistry analyzer
• minimum sample volume analyzer
• micro sample biochemical analyzer
• biochemical analyzer sample volume

However, sample volume should be considered together with analytical requirements and workflow.

What Sample Types Does the Analyzer Support?

Common biological samples used in clinical chemistry include:

• Serum
• Plasma
• Urine

The exact sample types depend on the analyzer and validated applications.

Before purchasing, ask:

Which sample types are supported?

Also check:

• Sample tube compatibility
• Sample cup compatibility
• Sample volume requirements
• Sample stability requirements
• Barcode support

Never assume that every biochemical analyzer supports the same sample types.

Step 5: Evaluate the Reagent System

The reagent system is one of the most important long-term considerations.

A laboratory may use an analyzer for many years, so reagent availability and cost can have a major effect on operating expenses.

Ask:

• What reagents are required?
• Is the system open or closed?
• Which reagent suppliers are supported?
• How much reagent is consumed per test?
• How should reagents be stored?
• What is the reagent stability?
• How often must reagents be replaced?

Open Reagent Biochemical Analyzer

An open reagent biochemical analyzer may provide greater flexibility in selecting compatible reagents, depending on the manufacturer’s specifications and validated applications.

Potential benefits may include:

• More reagent choices
• Purchasing flexibility
• Potentially easier local sourcing

However, compatibility must be confirmed.

A reagent should not be used simply because its chemical name appears compatible.

The analyzer, reagent, calibration, and testing method should be validated according to the applicable instructions.

Closed Reagent Biochemical Analyzer

A closed reagent system is designed around specified reagent configurations.

Potential benefits may include:

• Standardized workflow
• Defined reagent configuration
• Simplified operation

However, the buyer should understand the long-term reagent supply and operating cost before purchasing.

For international buyers, reagent availability in the destination market is especially important.

Step 6: Check Reagent Cost

The purchase price of the analyzer is only one part of the total cost.

For a laboratory performing thousands of tests, reagent consumption can become a major operating expense.

A useful comparison is:

Cost per test = Reagent cost + Consumables + Other variable testing costs

Buyers should ask suppliers for estimated reagent consumption for commonly used tests.

For example, compare:

• Glucose reagent consumption
• Creatinine reagent consumption
• ALT reagent consumption
• AST reagent consumption
• Cholesterol reagent consumption

This provides a more realistic view of operating costs.

Step 7: Consider Calibration

Calibration establishes the relationship between the analyzer’s measurement response and the expected analytical result for a specific test system.

Calibration requirements depend on:

• Analyzer
• Reagent
• Test method
• Calibrator
• Manufacturer instructions

Ask the supplier:

• How is calibration performed?
• How often is calibration required?
• Is calibration automatic?
• How many calibrators are needed?
• Can calibration information be stored?
• How is a new reagent lot calibrated?

These questions are useful when comparing clinical chemistry analyzers.

Step 8: Review Quality Control Functions

Laboratory quality control (QC) is another important consideration.

A biochemical analyzer may provide QC functions such as:

• QC result storage
• QC charts
• Control level management
• QC trend review
• Result flagging

The exact software features vary by model.

When comparing analyzers, ask:

How does the analyzer manage quality control data?

This is particularly important for laboratories with formal quality management systems.

Step 9: Check STAT Testing

Hospitals may need urgent laboratory testing.

STAT testing allows urgent samples to be prioritized.

If your laboratory handles emergency testing, ask:

• Is STAT testing supported?
• Is there a dedicated STAT position?
• Can STAT samples be loaded during routine operation?
• Does STAT testing interrupt routine testing?
• How are urgent results displayed?

STAT capability can be an important feature for hospital chemistry laboratories.

Step 10: Evaluate LIS Connectivity

Modern laboratories often need analyzers to communicate with laboratory information systems.

LIS stands for Laboratory Information System.

LIS connectivity can help with:

• Sample information
• Test requests
• Result transmission
• Data storage
• Laboratory workflow

Relevant search terms include:

• biochemical analyzer LIS
• chemistry analyzer LIS
• clinical chemistry analyzer connectivity
• laboratory analyzer integration
• LIS compatible chemistry analyzer

Before purchasing, ask the supplier:

• Does the analyzer support LIS?
• What communication interface is used?
• Is middleware required?
• Can results be transmitted automatically?
• Is barcode identification supported?

Barcode and Sample Identification

Barcode identification can help laboratories manage sample information.

A barcode system may allow the analyzer to associate:

Sample ID → Patient information → Test request → Result

The exact workflow depends on the analyzer and LIS.

For laboratories processing many samples, barcode support can be an important purchasing consideration.

Step 11: Check the Optical System

Many biochemical analyzers use photometric or spectrophotometric measurement.

Important specifications can include:

• Wavelength range
• Number of wavelengths
• Light source
• Optical measurement system
• Photometric range

However, a longer wavelength list does not automatically mean a better analyzer.

The key question is:

Does the optical system support the tests required by your laboratory?

Step 12: Evaluate Reaction System

The reaction system affects how samples and reagents are processed.

Important specifications may include:

• Reaction positions
• Reaction volume
• Incubation temperature
• Reaction time
• Mixing system
• Cuvette system

For automatic analyzers, also consider:

• Cuvette washing
• Cuvette replacement
• Carryover control
• Reaction monitoring

Step 13: Consider Carryover

Carryover refers to the possibility that material from one sample or reagent affects another measurement.

Modern analyzer designs may include procedures or system features intended to minimize carryover.

When evaluating a biochemical analyzer, buyers should ask the manufacturer about:

• Carryover specifications
• Probe washing
• Cuvette washing
• Reagent separation
• Sample handling procedures

This can be especially important for laboratories with high testing volumes.

Step 14: Check Analyzer Dimensions and Laboratory Space

Laboratory space is easy to overlook.

Before purchasing, measure:

• Bench length
• Bench depth
• Available height
• Service access
• Reagent storage area
• Waste area
• Operator working space

For a benchtop biochemical analyzer, the physical footprint may be relatively compact.

For a larger fully automatic chemistry analyzer, installation requirements can be more demanding.

Do not forget space for:

• Computer
• Printer
• Reagents
• Consumables
• Waste containers
• UPS or power protection equipment, if required

Step 15: Check Power Requirements

International buyers should confirm:

• Voltage
• Frequency
• Power consumption
• Plug type
• Electrical protection requirements

For example, a laboratory may need to determine whether the analyzer is compatible with its local electrical supply.

Ask the supplier for the official installation requirements before shipment.

Step 16: Evaluate Maintenance Requirements

Every laboratory analyzer requires maintenance.

Common tasks may include:

• Daily cleaning
• Probe cleaning
• Cuvette cleaning
• Waste disposal
• Reagent system maintenance
• Optical inspection
• Calibration
• Consumable replacement

Fully automatic systems may require more structured preventive maintenance because of their larger number of automated components.

Ask for the manufacturer’s:

• Daily maintenance procedure
• Weekly maintenance procedure
• Monthly maintenance procedure
• Preventive maintenance schedule
• Troubleshooting guide

What Is Preventive Maintenance?

Preventive maintenance means performing routine maintenance before a problem occurs.

For a biochemical analyzer, this can include:

• Cleaning
• Inspection
• Replacing consumables
• Checking probes
• Checking optical components
• Reviewing system warnings
• Performing recommended calibration procedures

Following the manufacturer’s maintenance schedule can help laboratories manage equipment operation more systematically.

Step 17: Consider Technical Support

When buying laboratory equipment internationally, technical support can be as important as the equipment itself.

Ask suppliers about:

• Installation
• Operator training
• Remote support
• On-site service
• Warranty
• Spare parts
• Preventive maintenance
• Troubleshooting
• Software support

For distributors, hospitals, and laboratories in regions far from the manufacturer, spare parts availability and response time can be especially important.

Step 18: Evaluate Training

A biochemical analyzer may have sophisticated software and automated functions.

Training can help operators understand:

• Sample loading
• Reagent loading
• Test selection
• Calibration
• Quality control
• Maintenance
• Error handling
• Result management

When requesting a quotation, ask whether operator training is included.

Step 19: Review Warranty Terms

Warranty terms can vary significantly between suppliers.

Ask:

• How long is the warranty?
• Which components are covered?
• Are spare parts included?
• Is labor included?
• Is remote support included?
• What situations are excluded?
• How are warranty claims handled internationally?

A clear warranty policy can make procurement easier.

Step 20: Check Spare Parts Availability

A laboratory may operate an analyzer for many years.

Therefore, buyers should ask about the availability of:

• Sample probes
• Reagent probes
• Pumps
• Valves
• Lamps
• Cuvettes
• Tubing
• Electrodes
• Other consumables and replacement parts

Long-term spare parts support can be important when selecting a biochemical analyzer manufacturer.

What Is the Cost Per Test?

Cost per test is an important commercial consideration for many laboratories.

A simplified calculation is:

Cost per test = Reagent cost + Consumable cost + Other variable costs

The actual calculation may be more complex because laboratories may also need to account for:

• Calibration
• Quality control
• Repeat tests
• Dilution
• Waste
• Maintenance
• Labor
• Equipment depreciation

When requesting a quotation, ask suppliers for estimated reagent consumption for your main test menu.

How to Choose a Biochemical Analyzer for a Small Laboratory

A small laboratory may prioritize:
