All Optical Activity quartz control plates are manufactured to the specifications laid down by I.C.U.M.S.A. (The International Commission for Uniform Methods of Sugar Analysis) and are available with or without the facility for temperature control of the plates. The quartz disc or discs are mounted in a central cell, which provides the best protection from dirt or careless handling. In the temperature controllable version, the central cell is thermally insulated from the supporting sections and can be connected to a thermocirculator to control the temperature by flowing fluid.
Optical Activity quartz plates are supplied in a fitted wooden box for safe storage.
Optical Activity quartz plates can be used in most polarimeters which accept the standard 30mm diameter end collars. Optionally, plates can be supplied adapted to fit polarimeters which require larger support collar diameters.
