Enabling Assays without Compromise

• Eliminate the need for purchasing and changing out filters for wavelength optimization with a monochromator-based wavelength selection for visible absorbance between 340 nm and 850 nm.
• Read up to 2 wavelengths in endpoint or kinetic mode for 96-well plates.

Measuring Accurately and Reproducibly

The VersaMax Microplate Reader offers:

• Better experimental signal discrimination using narrow absorbance bandpass for superior peak resolution and increased accuracy.
• Monitoring of temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C.
• Thorough mixing of samples in microplate wells by user-programmable Automix feature.

Comprehensive Reader Validation

Molecular Devices microplate readers have the most variety of tools available for users to meet their diverse hardware and software validation needs. Molecular Devices provides complete solutions with:

• SpectraTest® ABS1, FL1, and LM1 Validation Plates for hardware validation of absorbance, fluorescence, and luminescence modes
• IQ/OQ/PQ Instrument Qualification documentation
• SoftMax Pro Software validation package
• Software tools for FDA 21 CFR Part 11 compliance

Automating with Ease

• Seamless automation coupling with the StakMax Microplate Handling Stacker, Molecular Devices' own integrated microplate stacker designed exclusively for the VersaMax Microplate Reader
• Note:The StakMax Microplate Handling Stacker is compatible with the currently shipping reader, as designated with the serial number BNR-xxxxx. For older models, please contact your local sales representative.
• No physical modifications required to the automation-compatible design of the reader for integration into automated platforms. Molecular Devices' readers have been integrated into all major automation platforms.
