Opentrons Absorbance Plate Reader Module

Overview

The Absorbance Plate Reader Module is an on-deck microplate spectrophotometer exclusively for Opentrons Flex. It measures light absorbance in 96-well plates at up to 6 wavelengths simultaneously, enabling automated ELISA, cell density measurements, colorimetric assays, and kinetic readings without manual plate transfers.

Core value: Eliminate manual plate reader transfers. Read absorbance mid-protocol to make real-time decisions or collect kinetic data with automated timing and liquid handling.

Platform: Opentrons Flex only (not compatible with OT-2)

When to Use

Use the Absorbance Reader skill when:

• Running ELISA or other colorimetric assays requiring absorbance reading
• Measuring bacterial or cell culture growth (OD600)
• Performing kinetic assays with timed readings
• Collecting multi-wavelength absorbance data
• Protocols requiring real-time decision-making based on absorbance values
• Automating plate-based biochemical assays
