Pipette Glass

Glass pipette for precise liquid measurement and transfer. Durable, chemical-resistant, and ideal for accurate lab experiments and solution handling.

Pipette Glass

Application

Glass pipettes are used for:

  • Precise measurement and dispensing of liquids in chemical analyses.
  • Preparing standards and reagents in pharmacopeial labs.
  • Clinical and diagnostic sample handling.
  • Educational laboratory experiments.
  • Quality control testing in research and industrial settings.

Compliance Standards

Typical compliance standards (depending on type and class of pipette):

  • ISO 648 / EN ISO 648 — Volumetric glassware specification.
  • DIN 12696 — Graduated pipette manufacturing standard.
  • IS 1117:2018 — Indian standard for single volume pipettes.
  • USP / ASTM E-1044 & ASTM E-969 — For USP/ASTM-certified pipettes (Class A).
  • Batch or Individual Calibration Certificate — Meets quality traceability requirements.

Product Description

A glass pipette is a calibrated laboratory glassware instrument designed for precise measurement and transfer of liquid volumes. Constructed from high-quality borosilicate or soda-lime glass, the pipette ensures excellent chemical resistance, thermal stability, and optical clarity. It is calibrated “to deliver” (TD, Ex) under standard reference conditions for accurate volumetric work in analytical, pharmaceutical, clinical, and research laboratories.
