Mithras, the extremely versatile multimode microplate reader from BERTHOLD TECHNOLOGIES offers you a wide variety of technologies as there are:
Luminescence
Absorbance
Fluorescence (top and bottom)
Fluorescence Polarisation (FP)
AlphaScreen
BRET
FRET
HTRF®
Time-resolved Fluorescence
The Mithras LB 940 operates with dedicated optical paths (DOPS) to ensure the best available performance for each technology.
The unit combines fluorescence and luminescence modes with the uncompromised performance of dedicated instruments. The sensitivity of the luminescence function exceeds even that of the best dedicated plate luminometers.
BRET and FRET for receptor studies and protein/protein interactions can also be measured with exceptional sensitivity as well as homogenous fluorescence polarization assays.
Mithras can be supplemented with up to 4 reagent injectors %u2013 based on the proven and highly precise JET technology %u2013 and a temperature control unit for the microplates. That offers extensive opportunities to the users to perform a huge number of applications including enzyme activities, phagocytosis, calcium flux, cell viability, apoptosis, protein and DNA determinations or protein-protein interactions.
The software is supporting a multitude of functions including standard curves and kinetic data reduction as well as the 21 CFK part 11 requirements.
For medium level throughput environments such as ´assay development´ or ´secondary screening´ the instrument can be equipped with a stacker.

The WyattQELS (Quasi-Elastic-Light-Scattering) instrument contains a real time digital correlator. The correlator measures the autocorrelation function of the intensity signal from any one angle of the DAWN or from the 90 degree location of the miniDAWN. The correlator then calculates the hydrodynamic radius at each elution time in order to provide hydrodynamic radii over an entire chromatographic peak.
Unlike many other dynamic light scattering instruments, the WyattQELS detector, when interfaced to the DAWN, allows one to measure correlation as a function of angle. Particles larger than 150nm may scatter relatively little light at 90 degrees because of intra-particle interface or "Mie scattering".
Features
Multiple Tau correlation design with a fixed range of channel from 480 nsec to ~1 hour (real-time).
No sample time optimization required!
A total of 264 channels with input data format of 5 bit for the first 16 channels, the the sample time doubles every 8 channels and the data width is incremented 1 bit for every set of channels. No pre-scaling required.

Unique Proven Technology
> Reduce quarantine time
> The fastest response to contamination incidents
> Decrease inventory holding and warehouse costs significantly
> Rapid confirmation of corrective action effectiveness
> Minimize production disruption
> Decrease product losses
The CHEMUNEX Fluorescent Cell Labeling Technology (Fluorassure) has been widely used by the industry for more
than 15 years and is a well-established technology for the universal labeling of viable bacteria, yeasts and molds.
The ChemScan RDI® (Scan RDI® in the US) application using the fluorescent markers is approved by the FDA.
All and only viable microorganisms are labeled, even under conditions of stress such as the nutrient-depleted conditions of process water or in the presence of growth inhibitors, and are kept intact.
Chemunex technology provides direct labeling and detection, cell by cell. This provides results in microbial cell counts without the need of any calibration curve or interpretation.
3 analyzers are available for non filterable products: BactiFlow, BactiFlow ALS and D-Count

Voltammetry instruments and polarographs are favorably priced and compact, yet great in their detection capabilities.
- With voltammetry you can analyze trace elements in water, environmental samples or ultrapure chemicals!
- With the Cyclic Voltammetric Stripping technique (CVS) the analysis of organic additives in plating baths can be carried out easily and accurately.
Convincing applications
1) Apart from the determination of the total concentration, voltammetry allows to distinguish the different oxidation stages of metal ions or differentiate between free and bound metal ions as well as to specify the biological availability of heavy metals. VA instrument can also be used in mobile laboratories for environmental analysis.
2) Not only metals but also various organic compounds can be determined by voltammetry, but also some special anions. The determination of environmentally relevant anions like cyanide, sulfide, nitrite or nitrate is particularly interesting.
Automation makes work easier, increases sample throughputs and provides more exact results. For example, the CVS determination of organic additives in the plating industry can be carried out manually, partly automated or fully automated using the 838 Advanced Sample Processor.
