DEN-600 isa compact, portable, rechargeable battery powered photometer. DEN-600comprises of600 nm
wavelength optical system, which enables to apply -1) OD600 method thatestimated total number of cells,2)
McFarland (McF) turbidity measurement method,3) Bradford protein assay method for protein concentration
measurement
The deviceservesasan inexpensivealternativeto a spectrophotometer, which is commonly used for these
applications. Because DEN-600is battery powered and compact, it can becomfortably located in a biosafety
cabinet,anaerobic chamber or quickly moved to another lab room.Additionally, thevessel holding
mechanism allowsaccommodating standard 10 mm path cuvettes, round bottom, conical vials or falcon tubes,
thereforeenabling to measuretheabsorbanceand turbidity in Abs, OD or McF units.
USB connectivity and DEN softwareallow for data transfer, data processingand calculation, software
calibration for Bradford protein assay method ora custom calibration fora specifically applicablevesseland
custom turbidity standards.
