Bath Level
The level of a dissolution bath is often overlooked. It should not be assumed that the laboratory bench is level. This is one of the parameters that should be checked on installation and some dissolution testers have an in-built level checking device.
Testers which are not level can give erroneous results and the media rotation is not linear within the vessel.
Level should be tested front to back as well as side to side. A calibrated level will provide an accurate measurement of this. If the bath is moved for any reason then this parameter will need to be re-checked.
