Double Monochromator          TriStar² S LB 942 employs a double monochromator for absorbance and fluorescecence excitation. The monochromator is predominately meant to provide entire wavelength flexibility and spectral scanning posibilities in absorbance and fluorescence measurements, yet they can be used for Time-Resolved Fluorescence measurements as well.                    While a low f number and a high blocking ensure exceptional performance variable bandwidths and increments of 1 nm illustrate the versatility of the monochromators.                    Built-in Reagent Injectors          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.JET injector                    Berthold Technologies´ injectors are based on the proprietary JET Injection technology. Superior accuracy and precision is combined with excellent mixing performance. Variable injections speeds and "friendly" material enable even injection of live cells (e.g. in Aequorin based GPCR screening).          One of the injector tips is located in reading position enabling the measurement of very fast labels, e.g. Acridinium esters, and to inject activators into a running kinetic.                    The ergonomic design of the housing provides front access of the injectors keeping the reagent reservoirs within reach and within eyesight. A through allows keeping the reagent bottles on ice or elevated temperatures – just as required.                    Wash Plate          Excess fluids from priming and washing procedures are safely discarded via a specially designed wash plate.                    Temperature Control          A temperature controlled microplate compartment ensures stable conditions whenever temperature sensitive enzymes or cells are in use. Condensation of lidded microplates is reduced.                    Front Access of Reagents          The reagent reservoirs can be placed on the front for easy access and monitoring. A smoked see through lid protects the reagents from light. A base trough allows for the use of ice to keep the reagents cool.                    Modularity          In the TriStar² S any of reading technologies can be combined with each other and any of the options added.
