Dymanica Spectrophotomers Launched by Progen Scientific
07 August 2008
At Progen Scientific we constantly strive to bring our customers the latest quality products in the laboratory equipment market place. We are especially pleased to introduce a range of spectrophotometers from Dymamica. The three models in our range provide great functionality and a host of features designed for the modern laboratory. The models introduced include the Halo RB-10, a ratio beam spectrophotometer with an extensive array of built-in functions for versatility and suitability to many analytical and biological applications. The ratio beam optics impart greater accuracy and reproducibility than the conventional, single beam optics.
The absorbance signal in conventional single beam instruments can destabilise even during simple applications thus resulting in data inaccuracy. By contrast, ratio beam optics compensate and stabilise any signal fluctuations to increase accuracy and reliability even over prolonged usage such as in time course and kinetic measurements. The ratio beam principle involves splitting the beam generated by the light source by a half mirror. One of the split beams passes through the sample and is quantified by the detector whereas the other split beam, which is representative of the absorbance signal, is measured by an independent detector to obtain a signal reference. The ratio of the values from both detectors is then calculated to detect and compensate for any aberration in the energy of the light source or a temporal change of the optical elements and produce the highly stable photometric values.
