Photometer with Accu - DEN-600
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
Portable Photometer with Rechargeable Battery
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.
