Auto ESR Analyzer BK-ESR40

Automatic ESR analyzer uses advanced infrared light color difference interpretation technology to automatically scan the whole process of red blood cell sedimentation within 30 minutes for the sample of the vacuum blood collection tube, and refer to the Westergren method to measure the standard curve to obtain accurate results.


it’s applications are in hospital inspection departments, medical laboratories, research institutes, universities, disease control centers, etc.




  1. 7-inch color touch LCD screen, easy to operate, high resolution
  2. 80 samples/hour, rapid detection
  3. Randomly insert sample positions for testing at any time
  4. Built-in thermal printer for easy data printing
  5. Results are automatically temperature compensated
  6. Advanced optical testing principles to overcome reading errors in manual methods
  7. Power-off save function, automatically save the test results
