How to choose a biochemical analyzer filter?
The performance of biochemical analyzer filters directly affects the accuracy and repeatability of the test results. It is important to pay attention to it when selecting the model:
Wavelength matching (strictly against the requirements of the kit).
FWHM and OD value (balance sensitivity and anti-interference ability).
Durability (hard coating + bezel design for automated instruments).

For high-end applications (e.g. ultra-micro detection), it is recommended to choose ultra narrow band (FWHM<5 nm) + OD6 filters; for routine detection, it is recommended to choose wide band (20~40 nm) + OD4 to reduce the cost.
