ALL Modules
The Opentrons Flex Absorbance Plate Reader Module is a fully automated solution for absorbance-based assays. Capable of detecting absorbance in the 400-1000 nm range, it is optimized for a broad array of applications, including protein quantification, sample normalization, cell viability assays, and bacterial growth monitoring.
This module facilitates complete walkaway automation, enabling high-throughput data collection with no manual intervention. Paired with the Opentrons Flex Gripper, it automates every step from reagent prep to plate transfer to measurement, ensuring consistent and reproducible results.
The Opentrons Flex Absorbance Plate Reader Module is not available for sale in Europe.*
