New Compact Photometer Covers a Wide Range of Applications

The new DEN-600 Photometer from Biosan is a compact, portable, rechargeable battery powered photometer. 

The DEN-600 comprises of 600 nm wavelength optical system, which enables to apply, 1) OD600 method that estimated total number of cells, 2) McFarland (McF) turbidity measurement method, 3) Bradford protein assay method for protein concentration measurement. 

The device serves as an inexpensive alternative to a spectrophotometer, which is commonly used for these applications. Because DEN-600 is battery powered and compact, it can be comfortably located in a biosafety cabinet, anaerobic chamber or quickly moved to another lab room. Additionally, the vessel holding mechanism can accommodate round bottom, conical vials or falcon tubes, therefore enabling to absorbance and turbidity measurement in Abs, OD or McF units. 

USB connectivity and DEN software allows for data transfer, data processing and calculation, software calibration for Bradford protein assay method. It can also accommodate customised calibration for specifically applicable vessels and custom turbidity standards. 

Common applications include cell concentration measurement, cell growth data estimation, log phase estimation for microbial cells induction, competent cell preparation, Bradford protein assay method, antibiotic susceptibility testing and inhibitory tests.
