OMSONS Class B Glass Burettes with Rotaflow Stopcocks are standard volumetric instruments designed for routine laboratory titrations where extreme analytical precision is not required. They feature a screw-thread PTFE (Polytetrafluoroethylene) needle valve, often branded as a Rotaflow stopcock, which allows for smooth, "drop-by-drop" precision without the need for stopcock grease.

Key Features
  • Accuracy Grade: Class B (standard laboratory accuracy).
  • Material: Manufactured from Borosilicate 3.3 glass, providing high resistance to thermal shock and chemical attack from most acids and alkalis.
  • Stopcock Type: Rotaflow PTFE needle valve, which is self-lubricating, grease-free, and prevents the "freezing" common with glass stopcocks.
  • Graduations: Features permanent, high-contrast white or blue enamel markings for clear volume reading.
  • Compliance: Conforms to international standards ISO 385 and DIN/ISO 385
