Molecular Devices Spectramax 250 Microplate Reader

The Molecular Devices SpectraMax 250 Microplate Reader has an optical design that mimics a dual-beam spectrophotometer. Each sample has a discrete sample and reference beam so that each well is measured directly. The eight-channel system consists of 8 sample beams and 8 reference beams, delivering both superior precision and speed of reading across the microplate. The Spectramax 250s xenon flash lamp and grating monochromator facilitates direct UV measurement of DNA, RNA, and protein in microplates. Users can perform spectral scans from 250 nm to 750 nm to simplify qualitative analyses of numerous samples. Up to nine user-defined assay protocols can be saved in non-volatile memory for future use with settings including read mode, wavelength(s), auto mix state, blank pattern, and temperature setpoint. As a standalone unit, the SpectraMax 250 can obtain readings in either endpoint or kinetic modes.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Instrument Inspection and Recertification Checklist

Confirm the power supply and PCB output correct, stable voltages across all required connections
Inspect the display for any dim or dead pixels; replace affected components to maintain full visual clarity and operational accuracy
Verify full functionality of all buttons, ensuring precise and responsive input control
Check the XY assembly for proper movement and alignment; thoroughly clean all railings, removing any debris or contaminants
Confirm stable software communication and connection between the instrument and PC, addressing any connectivity issues
Inspect and clean or replace all filters as required to ensure optimal airflow and performance
Examine internal wiring and electrical connections for any breaks, disconnections, or tears; replace or secure any compromised wiring
Test the lamp’s full functionality, replacing it if any performance issues, dimming, or faults are detected
Execute the necessary validation protocol, documenting completion with a date on a calibration/verification certificate
Perform and verify appropriate updates to the PC operating system for compatibility and security
Conduct a thorough cosmetic inspection, ensuring all external components meet quality and aesthetic standards
