Many of the instruments used in Hospital Labs, such as Osmometers and Clinical Photometers, are also used in the Pharmaceutical Industry for Toxicology screening and for numerous Quality Control applications. These instruments are calibrated in mosmols but actually measure freezing point depression, very accurately, which is directly related to osmolality.
Several models are available depending on sample size and degree of automation.
The single sample Model 3300 and the multi sample Model 2400 which works with up to 20 samples at a time. Both the multi sample models have built-in printers and printers can also be attached to the single sample models thus providing a hard copy of the results, which is important for validation. These instruments are quick and easy to use, taking about one minute to reach a result, and are well suited to Quality Control applications for checking solution strength in critical situations such as IV fluids, contact lense solutions, isotonic drinks and all other liquid preparations. These instruments have been designed principally for the small to medium Hospital Biochemistry Lab, but are equally useful as compact programmable general purpose Photometers for routine Quality Control programmes. A ruggedised version is also available for on line plant applications.
