The DEN-600 is a compact, portable, rechargeable battery powered photometer. It's 600 nm wavelength optical system allows you to measure as below: Estimated total number of cells (OD600), turbidity measurement method (McFarland (McF)) and protein concentration measurement (Bradford protein assay method).rThe device serves as an inexpensive alternative to a spectrophotometer, which is commonly used for these applications. As the DEN-600 is battery powered and compact, it can be comfortably located in a biosafety cabinet, anaerobic chamber or quickly relocated. The cell holder accommodates standard 10 mm path cuvettes, round bottom or falcon tubes.rUSB connectivity and DEN software allow for data transfer, data processing and calculation.rrApplications:r- Cell concentration measurementr- Cell growth data estimationr- Log phase estimation for microbial cells inductionr- Competent cell preparationr- Bradford protein assay methodr- Antibiotic susceptibility testingr- Inhibitory testsrrSpecifications:r- Light source: LED, self-calibratingr- Wavelength (?, nm): 600±10r- Display: LCDr- Battery type: Lithium-ion polymer battery (LiPo)r- PC system requirements: Intel/AMD Processor, 1 GB RAM Windows Vista/7/8/10/11, USBr- Weight (Kg): 0.5r- Dimensions WxHxD (mm): 120x65x145
