The DSM-Cuvette™ is a light weight, battery powered, portable and very simple to use cell density meter. It can be used to measure yeast cells, E. Coli and other biological samples held in suspension, at a wavelength of 600nm. The machine comes preconfigured to provide testing using a standard 10 mm cuvette.
This instrument contains functions of logarithmic transmission absorption, % transmission and also comes with an intervalometer for time-lapse recording. This instrument's small size allows it to be used in small environmentally controlled spaces such as anaerobic compartments or incubation chambers.
A LED light source provides the 600 nm light that is fixated on the sample in order to aquire the results. An easy to use touch panel provides all the function buttons for convenient use. This control panel is made of glass for simple wipe down and spill clean-up.
A USB access port is given to link to a PC or printer which allows readings to be printed out or inputted as data into the computer for further analysis. A battery assembly that is fully charged can operate for 30 days free of AC power. It can also be recharged in 12 hours when the instrument is turned off.
Cleaning this machine can be done easily using simple regular agents found in the laboratory such as; ethanol or de-ionized water. It can be sterilized with formaldehyde or ethylene. Acetone and other organic solvents should not be used as it may errode the sites for the samples.
