The Ultrospec 10 cell density meter is a small, portable and easy to use instrument that is dedicated to measuring the density of cells in suspension at 600nm. It is suitable for measuring growth rates of all types of cell including E.coli and yeast and has been designed to give comparable readings to other spectrophotometers; it also has the benefit that it can be used in incubation cabinets and under anaerobic conditions. Spillages can be wiped from the smooth surface. The instrument has rechargeable batteries that are automatically charged when it is connected to the mains; it can be used for almost 1 month under normal operating conditions when fully charged, offering great flexibility. A 600nm LED source in combination with a fibre optic is used to obtain the optical density measurement. The instrument can be linked via a serial lead to either a serial printer for hardcopy output or to a PC for download of results to spreadsheet.
