A new unique ONE-4-ALL optical system has been applied to the instrument. It is the first time a single optical system is as efficient as dedicated systems. So, TriStar multilabel reader offers performances known from dedicated instruments. All common applications including DNA and protein quantification, Calcium monitoring, reporter gene assay, ATP determination, cell growth and viability, apoptosis, phagocytosis and enzyme kinetics will run on TriStar² LB 942 multitechnology plate reader. In addition, assays based on the reading technologies BRET, e.g. functional GPCR assays, and FRET for protein-protein interactions may be performed.

Up to 3 reagent injectors can be set up to dispense multiple activators or detection reagents at any time and with user-adjustable volumes during the measurement. Front access to reagents, a trough for holding ice and reagent holders add to the convenient and safe use of the instrument. Berthold Technologies´ injectors are based on the proprietory JET Injection technology. Superior accuracy and precision is combined with excellent mixing performance. Variable injection speeds and ""friendly"" material enable even injection of live cells.

A temperature controlled microplate compartment (5 °C above room temperature to 40 °C) ensures stable conditions whenever temperature sensitive enzymes or cells are in use.

3 modes each with variable speed of the integrated shaker to enhance mixing and optimise sample distribution before measurement in long term kinetics.
