Measurement Specifications

Measurement method Absorbance
Measurement techniques Endpoint and kinetic
Detection 96 photodiodes
Measurement range 0–4.0 optical density (OD)
Resolution 0.001 OD
Accuracy

The maximum deviation between the determined value and the true value.

At 405 nm:

  • ≤1.5% + 0.010 OD from 0.0–2.0 OD
  • ≤3% + 0.010 OD from 2.0–3.0 OD

At or above 450 nm:

  • ≤1% + 0.010 OD from 0.0–2.0 OD
  • ≤1.5% + 0.010 OD from 2.0–3.0 OD
Reproducibility

The maximum deviation between the determined values when the measurement is repeated directly.

  • ≤0.5% + 0.005 OD from 0.0–2.0 OD
  • ≤1% + 0.010 OD from 2.0–3.0 OD
Linearity

The maximum deviation between the true and the determined increase of the value.

At 405 nm:

  • ≤1.5% from 0.0–2.0 OD
  • ≤3% from 2.0–3.0 OD

At or above 450 nm:

  • ≤1% from 0.0–2.0 OD
  • ≤1.5% from 2.0–3.0 OD

Detection Wavelengths

The Absorbance Plate Reader emits light in the visible spectrum at 450 nm (blue), 562 nm (green), 600 nm (orange), and 650 nm (red).

Status Light

The Absorbance Plate Reader has a single status light on the lid. It illuminates in different colors and patterns to indicate various operating conditions.

Color Pattern Status
White Solid The module is on and ready.
Pulsing Self-test after connecting to power.
Various Solid Initialization/measurement in progress. The status light color corresponds to the selected light wavelength used for analysis.
Yellow Pulsing A well plate is inside the reader.
Red Blinking An error has occurred.

Input and Output Connections

The Absorbance Plate Reader has the following power input requirements, which are met by its USB connection to a Flex robot.

  • Input: Power from a USB port with 5 VDC and a maximum of 3 A.
  • Power consumption: 2.5 W
  • Fuse: 1 A (very fast acting)
