Technical Information:



 

The DSM-Cuvette TM instrument is a cell density meter that is portable, light weight, easy to use and battery powered. The device functions as cell density meter for measurement of E. Coli, yeast cells and other biological agents in suspension at the 600 nm wavelength of light.

The instrument has the functions of % transmission (% T), logarithmic transmission absorption (Abs) and also provides an intervalometer for time-lapse recording. The instrument is sized to permit it to be used in smaller spaces, used in incubation chambers, anaerobic compartments or other environmentally controlled areas.

A LED provides 600 nm light that is focused to the sample to obtain the readings. A simple touch panel provides all the function buttons. The control panel with the user buttons is constructed of glass for easy wipe down and spill clean-up.

A USB 2.0 port is provided to connect to a PC.  The PC connection provides a method to input the instruments data collected for further analysis. A fully recharged battery assembly will provide 30 hours of operation free of AC power. The recharge time is 1-2 hours when the instrument is turned off.

Cleaning the instrument can be accomplished using common laboratory agents like de-ionized water, ethanol, or sterilized with formaldehyde or ethylene. Organic solvents like acetone should not be used as it may degrade the sample sites.

The DSM-Cuvette TM comes preconfigured to provide testing using a standard 10 mm cuvette.
