What are the functions of a microplate reader filter?
Wavelength Selection: filters allow light of a specific wavelength to pass through, while other wavelengths are blocked, ensuring specificity and accuracy of detection.
Distinguish Signals: in fluorescence or absorbance detection, filters separate Excitation and Emission, reducing background interference.

What are the maintenance and common problems with microplate reader filters?
Maintenance:
(1) Cleaning: wipe gently with a dust-free cotton swab and optical cleaner to avoid scratching the coating.
(2) Calibration: check the wavelength accuracy of the filter periodically (especially after long-term use).

Failure performance:
(1) Signal weakening: may be due to aging or contamination of the filter.
(2) Elevated background: damaged filters or bandwidth shift.
