Highlights

Detection Technologies

The Tristar 3 Multimode Microplate Reader provides you with the flexibility for today, tomorrow, and beyond to master your changing plate reading applications:

  • High-sensitivity Luminescence
  • BRET
  • Absorbance (UV/VIS)
  • Fluorescence
  • FRET

Broad wavelength range selection from UV through the visible range

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.

BRET/BRET2 and NanoBRET™ upgradable

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™.

ONE-4-ALL Optics for uncompromised performance

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.

High-performance filter system - when sensitivity counts

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 like Time-Resolved Fluorescence is 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. BRET, BRET2 and NanoBRET™ assays.

Ergonomic design to support your work

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.

Powerful crosstalk control – reliable results

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 crosstalk, 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.

JET injectors: highest accuracy, speed and cell-friendliness

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.

  • Highest accuracy and reproducibility with greater than 98 % accuracy and reproducibility over the entire volume range.
  • Low reagent consumption due to the low dead volume and the injectors can recover up to 60 % of the reagent in the injector line. A single priming sequence is enough to achieve a 99 % homogeneous mix at the tip.
  • Low maintenance costs – friction-free operation enables more than 3 million injections without mechanical failure.
  • Optimal performance in flash-kinetics - ultra-fast injection enables the measurement of the first 150 ms of a kinetic assay (e.g. Fura-2 or Acridinium ester assays).
  • Worry-free injection of cell suspensions - negligible shear forces are ideal when working with living cells, e.g. in Aequorin-based calcium assays

Convenient Software options

Choose between different software options according to your application needs:

ICE Software

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.

MikroWin Software

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.
