Photometer with Accu - DEN-600

Portable Photometer with Rechargeable Battery

DEN-600 is a compact, portable, rechargeable battery powered photometer. 

Photometer comprises of 600 nm wavelength optical system.

The device serves as an inexpensive alternative to a spectrophotometer, which is commonly used for these applications.


  • Cell concentration measurement
  • Cell growth data estimation
  • Log phase estimation for microbial cells induction
  • Competent cell preparation
  • Bradford protein assay method
  • Antibiotic susceptibility testing
  • Inhibitory tests 
600 nm, McF/Abs

DEN-600 for Optical Measurements

The photometer is a flexible and compact instrument. Since it is battery powered, it can be conveniently placed in a workstation or anaerobic chamber or easily transported to another room.

It enables to measure the absorbance and turbidity in Abs, OD or McF units.


  • OD600 method that estimated total number of cells
  • McFarland (McF) turbidity measurement
  • Bradford protein assay method for protein concentration measurement
