Photometer 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.

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

Part Number: 103.3506

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.

Methods

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

Compatible Vessels

  • Standard 10 mm path cuvettes;
  • round bottom tubes
  • conical vials or Falcon Tubes

USB and DEN Software

  • Data transfer;
  • Data processing and calculation;
  • Software calibration for Bradford-Protein-Assay method;
  • Custom calibration for a specifically applicable vessel;
  • Custom turbidity standards.
