The Tristar 3 Multimodeprovides you with the flexibility for today, tomorrow, and beyond to master your changing plate reading applications:
From UV absorbance for DNA quantification to measurements in the far red or NIR, the Tristar 3 is ready for any assay and greatly improves the wavelength range of the TriStar².
All Tristar 3 preconfigured models have the features you need to perform BRET assays: best-in-class luminescence sensitivity and a high quality filters. To start working with BRET, just order the correct filters for BRET1, BRET2, and NanoBRET™.
Our patented ONE-4-ALL optics have been optimized to combine the stability and user-friendliness of a multimodal optical system with the sensitivity and versatility of a dedicated optical devices.
ONE-4-ALL optics work with both filter and monochromator based applications, so there is never a compromise in performance in any mode.
The quick-change filter technology of the Tristar series provides you with the flexibility required to meet your application needs. With your choice of up to 40 different excitation and emission filters can be easily mounted on exchangeable filter slides.
The filters are characterized by high transmittance properties which can be up to 25-fold more sensitive than monochromators. Technologies likeis measured more efficiently with filters.
Furthermore, filters with a large bandwidth are available to analyze fluorophores with wide spectra and all luminescence-based assays requiring the use of filters, e.g.assays.
The ergonomic design of the system provides full frontal access for all key operations (e.g. plate loading, filter change and connecting reagents). Reagent vials can be stored in the integrated front compartment providing easy access and visibility. The Tristar 3 contains a removable trough that can be filled with water or ice to keep all of your temperature sensitive reagents cooled. Different reagent tube holders are available to ensure secure handling of valuable reagents. The system has a flat surface on top, providing enough space for a laptop.
Do you often see a few high-intensity samples surrounded by wells of low-intensity when running your samples? Then you are potentially affected by a phenomenon called, this can produce wrong results and wrong conclusions. The crosstalk reduction design of the Tristar 3 almost eliminates this problem: with a crosstalk of 10-6, you will never have to worry about the position of your high-intensity samples in your plate.
The Tristar 3 can be equipped with up to 3 JET injectors with variable volumes in pre-measurement or measurement position. The ultra-fast injection speed of JET injectors eliminates any delay between injection and measurement. This enables the Tristar 3 to measure ultra fast reactions, e.g. flash luminescence.
Berthold Technologies JET injectors use Teflon bellows for accurate and fast injections. This guarantees the most efficient mixing as well as extreme longevity.
Choose between different software options according to your application needs:
ICE software is an intuitive, user-friendly software that walks you through the entire process of setting up your parameters, collecting your data and reporting the results. The software package is as flexible as your research, thanks to the many different combinations of operating sequences.
The MikroWin software is a complete software solution providing instrument control, data collection, analysis and reporting. The software is available in several different versions for all user needs. The complete Advance version of the software provides 21 CFR Part 11 compliance and additional QC features like audit trail or configurable user hierarchies.
For many laboratories ensuring compliance with a number of GMP and GLP requirements is essential. We provide a number of tools and services to help you ensure that your system is running at peak performance.
