Differential somatic cell count (DSCC) is a new milk testing parameter introduced with the Fossomatic™ 7 DC analyser. It complements the established test for total number of somatic sells (SCC) pioneered by FOSS in the 1980’s. The Fossomatic™ 7 DC has several sensors detecting fluorescence signals from milk cells and a new chemistry and an incubation unit. Combined, they enable the instrument to measure DSCC and SCC simultaneously.
MilkoScan™ 7 RM has a diamond cuvette backed by 10 years guarantee. Optics are optimized on the interferometer module increasing the signal/noise ratio, ensuring the same high performance at all cadences and improving repeatability for minor constituents.
Raw milk containing abnormalities is a growing problem. The abnormalities can be caused by deliberate adulteration, for example, with lard or melamine or by accidents if water or cleaning agents are mixed with the milk. With the MilkoScan™ you can screen incoming raw milk samples to identify a suspect raw milk sample quickly and as a normal part of everyday testing. The suspect sample can then be further analysed to determine the contaminant.
