Infrared LED detection
Optical measurement of erythrocyte sedimentation for reproducible, Westergren-equivalent results.
Automatic ESR Analyser
ZellESR® Automated Westergren ESR Analyzer with Infrared LED Detection
Sedimentation, simplified — automated Westergren-standardized ESR with infrared LED detection and random-access loading.
- Infrared LED detection
- Westergren method, automatic 18 °C compensation
- 20 channels, random access
- Results in 30 / 60 minutes (12-minute early indication)
Overview
ZellESR® esr analyzer
ZellESR® delivers automated erythrocyte sedimentation rate testing with Westergren-standardized results, infrared LED detection, and minimal manual handling.
Read the full overview
Erythrocyte sedimentation is measured by infrared LED detection and reported as Westergren-equivalent results in 30 or 60 minutes, with automatic temperature compensation to 18 °C (Manley table). Vacuum tubes with 3.8% sodium citrate load in random access, and an early pre-indication is available at 12 minutes.
A 4.2-inch color touchscreen, built-in thermal printer, barcode scanning, and LIS connectivity over RS-232 / HL7 keep the workflow simple and traceable.

Who is it for?
Hospitals, clinical laboratories, and research facilities that need standardized, automated Westergren ESR.
What problem does it solve?
Manual Westergren ESR is slow, operator-dependent, and difficult to standardize, limiting throughput and reproducibility.
Key features
Automatic temperature compensation
Results are compensated to 18 °C using the Manley table for consistency across conditions.
Random-access loading
3.8% sodium-citrate vacuum tubes load in random access, with an early indication available at 12 minutes.
Built-in thermal printer
On-board printing plus barcode scanning and manual entry for flexible operation.
Wide range & accuracy
1–140 mm/hr measurement range with ±1 mm accuracy and CV < 5%.
LIS / HL7 ready
Connects to the laboratory information system over RS-232 with HL7.
