The Tristar 5 Multimode Microplate Reader provides you with application flexibility for today, tomorrow, and beyond to master your changing plate reading applications. The system supports the following wide range of detection modes:
The Tristar 5 system is equiped with FlexTec Optics, offering you the best of two worlds – benefit from the flexibility to easily select a discrete wavelength and perform spectral scans for both, excitation and emission using its built-intechnology. Or optimize your assays´ sensitivity by utilizing the system filter sliders for excitation and emission. Or mix both technologies if required: the Tristar 5 delivers both, flexibility and sensitivity in a single system.
The Tristar 5 employs up to two double monochromators providing blocking properties needed in sensitive fluorescence assays. Both monochromators are equipped with software driven continuous bandwidth variation to optimise the instrument for the specific demands of different assay conditions.
Berthold´s flexible monochromator technology offers you variable bandwidths from 4-12 nm in excitation and 8 – 22 nm for emission, selectable in 1 nm increments.
From UV absorbance for DNA quantification to measurements in the far red or NIR (in selected configurations), the Tristar 5 is ready for any assay.
The Tristar 5 enables you to read both, from below as well as from the top with high-performance. The advancedof the system can be easily selected via the software to help you analyse e.g. adherent cells and obtain best sensitivity and a superior signal-to-background ratio for these applications.
Our patented ONE-4-ALL optics have been optimised to combine the stability and user-friendliness of a multimodal optical system with the sensitivity and versatility of dedicated optical devices.
ONE-4-ALL optics work for both filter- and monochromator-based applications, so there´s 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: up to 40 different excitation and emission filters can be easily mounted on exchangeable filter slides.
The filters are characterized by high transmissions properties which can be up to 25-fold that of monochromators. Technologies likecan be measured more efficiently with filters.
Furthermore, filters with a large bandwidth are available to analyze fluorophores with wide spectra and all luminescence-based assay requiring to use filters, e.g.or NanoBRET™ assays.
The ergonomic design of the system provides full front access for all key operations (e.g. plate loading, filter change and connecting reagents). Reagent vials can be stored in an integrated front compartment, providing easy access and visibility. It contains a removable trough that can be filled with water or ice to keep all reagents cooled. Different reagent tube holders are available to ensure secure handling of valuable reagents. The system has a flat surface on its top, providing enough space to put down a laptop.
Do you often see a few high-intensity samples surrounded by wells of low-intensity when running your samples? Then you´re potentially affected by a phenomenon called, that can produce wrong results and, hence, wrong conclusions. The crosstalk reduction design of the Tristar 5 does almost eliminate this problem: with a crosstalk of 10-6, you never have to worry about the position of your high-intensity samples in your plate.
The Tristar 5 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 and enables measurement of fast reactions, e.g. flash luminescence.
Berthold Technologies' JET injectors use Teflon bellows for accurate and fast injections and guarantee most efficient mixing as well as extreme longevity.
Choose between different software options according to your application needs:
ICE software is an intuitive, wizard-guided software that walks you through the entire process of setting up your system, collecting your data and reporting the results. The software package is as flexible as your research thanks to the many setting options and freely configurable 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 different versions, reflecting different 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, validation, qualification and 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
We provide a variety of tools to help you check and confirm the performance of your products over time.
