Absorbance Linearity Test Report in Checkmark Software

The Checkmark reader performance verification kit consists of an absorbance calibration plate and Checkmark software. This kit is an IQ/OQ tool that can be used to validate instrument performance parameters of Bio-Rad absorbance microplate readers.

The Checkmark check plate is compatible with all Bio-Rad absorbance microplate readers and is NIST-certified to confirm calibration traceability. Checkmark software allows automated testing of Bio-Rad absorbance microplate readers and generates reports specific to instrument type and serial numbers to ensure GLP compliance.Performance verification parameters include:

  • Accuracy
  • Precision
  • Linearity
  • Plate positioning (96-well plate format only)
  • Cross talk (best and worst case)
  • Filter check
  • 0 OD and overflow (100% and 0% transmittance)
  • Spectral blocking 

Checkmark software is compatible with Windows XP and Windows Vista operating systems.
