BioSan DEN-600 Photometer

The BioSan DEN-600 is a compact, portable, rechargeable, battery-operated photometer. DEN-600 consists of an optical system with a wavelength of 600 nm: 1) OD600 method to estimate the total number of cells, 2) McFarland (McF) turbidity measurement method, 3) Bradford protein analysis to measure the protein concentration. The instrument serves as a cost-effective alternative to a spectrophotometer commonly used for these applications. Because the DEN-600 is battery powered and compact, it can be easily placed in a biosafety cabinet, an anaerobic chamber or quickly moved to another laboratory space. In addition, the holding mechanism vessel can accept standard 10mm pad, round bottom conical vials or falcon tubes, allowing absorption and turbidity to be measured in Abs, OD or McF units. USB connectivity and DEN software enable data transfer, data processing and calculation, software calibration for the Bradford protein determination method or custom calibration for a specific applicable vessel and custom haze standards.
