Berthold Technologies update products at Analytica
instruments that will open up new opportunities for users in
bioimedical and pharmaceutical research.
Its TriStar LB 941is a step up from the company's LB 940 and takes the proven detection sensitivities of this instrument. The LB940 contains the optimised optical paths for the reading technologies absorbance, luminescence and fluorescence
The LB 941 can use optical emission filters to measure the functional assays for GPCR research as well as multicolour luciferases (reporter gene assays).
The LB 941 can be equipped with a universal detector - besides the photo diode for absorbance reading - for fluorescence and luminescence measurement.
Alternatively, each type of reading positions can be equipped with a separate detector. This opens the unique opportunity to even use different detectors with different spectral properties matching the luminescence and fluorescence applications respectively.
The product has the potential to offer users performance capabilities in enzyme activities, phagocytosis, calcium flux, cell viability, apoptosis, immunoassays, protein and DNA determinations or protein-protein interactions.
Berthold also has a presence in radioactivity flow having introduced its new instrument, FlowStar.
Taking elements from its predecessor LB509, the FlowStar is a newly developed instrument, which now includes a touch screen, as well as an automatic measuring cell recognition and two integrated bipolar analog inputs.
Designers at Berthold have also improved functionality, particularly for GLP/GMP primarily so the user can continuously supervise all relevant parameters for GLP/GMP by keystroke.
The FlowStar can easily be integrated in available HPLC systems by using the analog output signals. For a PC based solution the versatile RadioStar control - and evaluation - software is provided.
Berthold said that a new module (DLL interface) to implement the FlowStar into other HPLC System would become available soon.
Staying with Berthold's drive to modernise their technology, the company also introduce the third generation of low light imagers, which builds on the progress Berthold have made with their LB 940 Mithras.
This new technology, the LB 983 NightOWL II, enables quantitative fluorescence measurements.
This is achieved by the accuracy of the 16-bit lamp energy factor. With such a lamp setting the light beam is kept stable and reproducible for each measurement.
The settling time of the lamp requires maximal 2 seconds, filter changing needs 300ms.
More details of Berthold's technology can be found on the company's >website.
