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 PHERAstar® FSX is our most sensitive multi-mode reader for high-throughput screening, combining this sensitivity with fast read times. Thanks to the unique Optic Module system, Simultaneous Dual Emission, Enhanced Dynamic Range technology, UV/vis spectrometer, AAS System, and dedicated AlphaScreen® and TRF lasers, the PHERAstar FSX will perform your assay with ease and speed, even in 3456-well microplates.


No longer worry about installing filters and dichroics: the PHERAstar FSX comes with easy-to-handle, assay-optimized Optic Modules which contain all application-specific filters, mirrors, dichroics and/or polarizers, and are automatically recognised by the plate reader. In addition, the PHERAstar FSX is equipped with four matched and assay-optimized photomultiplier tubes (PMTs) which are automatically selected for the relevant detection mode. You can also measure assays with two emission wavelengths at the same time thanks to the Simultaneous Dual Emission.
The Enhanced Dynamic Range and automatic focus technologies make manual settings superfluous and detection optimisation easier than ever.
For HTS automation purposes, the PHERAstar FSX can be easily integrated into automated systems, and offers improved robotic integration capabilities and multi-user control.
The PHERAstar FSX is for research use only.
