Molecular Devices SpectraMax Plus Microplate Reader

The Molecular Devices SpectraMax Plus is a UV/Vis spectrophotometer/microplate reader with built-in cuvette port and microplate drawer. The instrument reads any standard cuvette, microcuvette, test tube and 96 well or UV transparent microplate over full 190-1000 nm wavelength range. This SpectraMax Plus comes from a long history of reliable tools built by Molecular Devices. This robust system is capable of reading 96 wells, each with its own sample beam and reference detector.

The nine channel system (8 for the microplate; 1 for the cuvette port) consists of sample beams and reference beams that mimic a dual beam spectrophotometer.

The path check sensor eliminates optical pathlength as a factor (and corrects pipetting variation), closing the gap between microplate readers and spectrophotometers. The SpectraMax Plus measures liquid depth and volumes down to 5µl in each microplate well and scales the microplate data to standard 1 cm cuvette values. The monochromator selects wavelengths in 1nm increments, and the system is equipped with built-in programmable linear and orbital plate shaking device.

Key Applications:
>DNA Analysis
>Endpoint Analysis

The Molecular Devices SpectraMax Plus Microplate Reader includes:
  • > Windows 10 Data Station with Pre-Loaded SoftMax Pro Software 5.4
  • > Interface Cable
  • > Operator's Guide
  • > Calibration Report
  • > Power Cord
  • > Full 90 Day Parts and Labor Warranty
