A measure of how strongly a substance absorbs light at a given wavelength. Used in NanoQ protein quantification modes (e.g., Molecular Extinction Coefficient, OD1) to calculate concentration from absorbance.

A test to detect bacterial endotoxins in pharmaceutical and biological products using the Limulus Amebocyte Lysate (LAL) method. MRX A2000 supports kinetic turbidimetric endotoxin analysis as an optional mode.

Enzyme-Linked Immunosorbent Assay. A plate-based assay technique used to detect and quantify proteins, antibodies, and hormones. A primary application of microplate readers such as the MRX Series.

A digital authentication mechanism used to verify user identity and intent in regulated laboratory environments. Required by FDA 21 CFR Part 11. Supported by K LAB’s Secure software.
