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.
The SPECTROstar® Omega is a dedicated absorbance microplate reader that can capture a full absorbance spectrum (220 - 1000 nm) in less than 1 second per well – no scanning needed. This upgradeable reader offers the highest flexibility for optimizing settings for all absorbance-based assays. The LVis Plate compatibility allows for low-volume sample measurements.

The SPECTROstar Omega is a dedicated absorbance microplate reader that can capture either a full-absorbance spectrum or up to eight discrete wavelengths simultaneously. Upgrades can transform the SPECTROstar Omega into a powerful multi-mode reader with up to three detection modes, Simultaneous Dual Emission and injectors.
The SPECTROstar Omega is for research use only.
