Technical Information:
The DSM-Micro 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
via fiber optic cables 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-Micro TM comes preconfigured to provide
testing using extremely small drop 20 ul samples.
