Ultra-Sensitive Tube Luminometer
True photon counting technology coupled with selected low noise photomultipliers and an optimised optical design is the only accepted way to achieve a low and stable background.
This is a major parameter for high sensitivity in a luminescence measuring system enabling detection of extremely low amounts of Adenylate Kinase.
- • less than 1 amol ATP per tube
• less than 0.5 zmol firefly luciferase per tube
Photon counting technology is characterised by a large dynamic range defined at the lower end by the low noise of the selected photomultiplier. The upper end is defined by the ability of the counting electronics to record and differentiate single pulses out of an avalanche of pulses. The PR2A is able to count up to 25 Mio pulses per second equivalent to a dynamic range spanning 7 orders of magnitude.
As no additional adjustments (such as gain and high voltage settings) are needed the PR2A offers convenience and security for every measurement over the entire life of the instrument.
Precise mechanics and the intrinsic stability of photon counting technology guarantee unrivalled repeatability of measurements. The instrument´s performance is stable over years. Time consuming daily calibration is thus unnecessary and you can concentrate on other and more important duties. The PR2A also features a self diagnostic performance verification cycle for absolute assurance.
Loading of the tubes is as easy and straight forward as defining a measurement protocol and as starting a measurement with the user-friendly ICE software.
