Features: • Stirrers IS 6 and IS 12 have been specially developed for BOD measurement with the OxiTop® system. • Software-controlled speed regulation prevents the magnetic stirrer bar from getting caught or wobbling. • The speed is selected so that an optimal gas exchange with the sample takes place. • The stirrer is maintenance-free and non-wearing as it contains no moving parts. • The IS 6-Var model has been specially developed for use with large Measuring vessels and has space for 6 measuring vessels. • Its outer dimensions are identical to those of the IS 12.
