OMSONS Class B glass burettes with Rotaflow stopcocks are standard volumetric instruments for routine laboratory titrations where extreme analytical precision isn't required. They have a screw-thread PTFE (Polytetrafluoroethylene) needle valve, often branded as a Rotaflow stopcock, for smooth, drop-by-drop precision without needing stopcock grease.

They're Class B accuracy (standard laboratory accuracy), made from Borosilicate 3.3 glass for high resistance to thermal shock and chemical attack from most acids and alkalis. The Rotaflow PTFE needle valve is self-lubricating and grease-free, and prevents the "freezing" common with glass stopcocks. Graduations are permanent, high-contrast white or blue enamel markings, and they conform to international standards ISO 385 and DIN/ISO 385.
