The DEN-600 is a compact, portable, battery-powered spectrophotometer with a 600 nm wavelength optical system that allows you to make measurements such as: estimation of total cell counts (OD600), turbidity measurements (McFarland Units), and protein concentration measurements (Bradford Protein Assay). Spectrophotometers are commonly used in these applications, making the DEN-600 an affordable alternative to spectrophotometers.

Since DEN-600 is battery powered and compact, it can be easily placed in biosafety cabinets and anaerobic chambers. The device can accommodate standard cuvettes with a 10mm optical range, common round-bottomed tubes with a diameter of 12-16mm, or centrifuge tubes, etc. A USB connection and the DEN software allow for data transfer, data processing, and calculations.
