Technical Information:
The DSM-Dual TM instrument is a cell density meter
that is portable, light weight, easy to use and battery powered. The device
functions as a 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-Dual TM comes preconfigured to provide testing
using extremely small drop 20 ul samples or using a standard 10 mm cuvette.
