ESR Analyzers — Automated Erythrocyte Sedimentation Rate Testing
An ESR analyzer automates the erythrocyte sedimentation rate test — a widely used, non-specific marker of inflammation. SSQLLC offers two automated ESR analyzers built for different laboratory workflows.

Buying criteria
Compare what matters
Sample-type fit
Choose EDTA-tube ESR (ZBT-ESR®) or Westergren citrate-tube ESR (ZellESR®) to match your draw workflow.
Throughput options
From single-sample simplicity to 20-sample random access for busier laboratories.
Standardized results
Automated measurement improves reproducibility versus manual ESR observation.
LIS / HL7 connectivity
Connect to the laboratory information system for traceable, paper-light reporting.
Compact & simple
Small footprints and touchscreen operation suit benchtop use with minimal training.
Low waste
Designed for efficient sample use and reduced liquid waste.
How to choose
Choose ZBT-ESR®
When you want ESR directly from the EDTA / CBC tube with no separate sample and a very small footprint.
Choose ZellESR®
When you need the Westergren method, random-access loading of up to 20 samples, and onboard result storage.

What is an ESR analyzer?
ZBT-ESR® measures ESR directly from the standard EDTA / CBC tube, while ZellESR® uses the Westergren method with infrared measurement and random-access loading of up to 20 samples.
An ESR analyzer measures how quickly red blood cells settle in a sample over time, reported in mm/hr. It is used to screen for and monitor inflammation across many clinical conditions.
Automated ESR analyzers improve standardization and turnaround compared with manual Westergren observation, while reducing operator handling and variability.
What buyers should evaluate
Key selection criteria include sample type (EDTA vs citrate), throughput and random-access needs, measurement time, result storage, and laboratory information system (LIS) connectivity.
SSQLLC ESR analyzers support LIS / HL7 connectivity, compact footprints, and simple touchscreen operation to fit routine laboratory and hospital use.
Frequently asked questions
EDTA-tube analyzers like ZBT-ESR® run ESR from the standard CBC tube, while Westergren analyzers like ZellESR® use citrate tubes and the reference Westergren method with infrared measurement.
Yes. Both ZBT-ESR® and ZellESR® connect to the laboratory information system over RS-232 with HL7 protocol support.
ZBT-ESR® suits laboratories that want ESR from the EDTA tube with minimal handling, while ZellESR® suits laboratories that need Westergren throughput with random access.
