The WPA cell density meter is a very affordable, easy to use instrument designed to the measure of the density of cells in suspension such as E.coli, yeast, cells and other cell cultures.
The CO8000 has an integral battery allowing it to be taken to where the cell cultures are growing e.g. in incubation cabinets, under anaerobic conditions or even in a fume hood or safety cabinets.
The CO8000 cell density meter will accept a variety of cuvettes and tubes- including 10, 12, and 16mm diameter test tubes meaning it can be used with Erlenmeyer side arm flasks. With no warm up time, just switch it on and it's ready to use giving you results that are comparable to larger, more expensive spectrophotometers.
