Colorimetric and turbidimetric analysis of endotoxins using the absorbance detection mode
Torn between a colorimetric or turbidimetric LAL assay? Whichever path you take, BMG LABTECH’s absorbance readers deliver dependable results every time.
BMG LABTECH’s innovative absorbance microplate reader has the flexibility to perform assays quickly and easily in both microplates or via the built-in cuvette port. This spectrometer-based absorbance microplate reader captures a full UV/visible spectrum in less than 1 sec/well. Its speed, simple push button operation, and capacity to store individual assay protocols make the SPECTROstar® Nano the leading microplate reader for absorbance measurements.

The SPECTROstar Nano is equipped with BMG LABTECH’s ultra-fast UV/vis spectrometer, which allows users to measure full-spectrum absorbance (220 – 1000 nm) in less than 1 second per well. It is the ideal instrument to read all absorbance assays in a microplate or cuvette – with many common assay protocols predefined and available at the click of the mouse.
The SPECTROstar Nano is for research use only.

BMG LABTECH microplate readers are built to be robust and reliable. No calibration of optical components is required. Recommended maintenance includes plate carrier offset adjustments, cleaning optical components, software/firmware updates, and routine performance checks.
