The Libra S6 visible diode array spectrophotometer has been designed to meet the routine spectroscopy needs of customers requiring a compact, light weight instrument that is easy to use and which includes far more features than similar priced products.
The Libra S6 measures absorbance, percent transmission, absorbance ratio, concentration and kinetics. A large backlit graphical display enables wavelength scans, kinetic assays (including slope calculation) and standard curves to be viewed. The Libra S6 accepts standard 10mm pathlength glass or disposable cuvettes. A test tube adapter set is available for 10, 12 and 16mm glass test tubes (COD measurements can be made using standard 16mm tubes).
GenePro has been evaluating the Libra S6 as an alternative to the expensive CASA determination of sperm concentration and the results are in. The results from both dose and ejaculate sperm concentration determinations are very accurate with variations as low as three-percent on extended doses and two-percent on whole ejaculates. Cost per sample are significantly lower when utilizing a stardard 12mm test tube compared to the Leji Chamber, (~80 cents vs. < 1 cent). Our conclusion is that the Libra S6 is a fast, accurate, cost effective way to determine semen concentration with out the extra costs of a complicated CASA system.
