This Class B glass burette has a PTFE stopcock and is a graduated, slender glass tube for dispensing liquids precisely, mainly for titration and chemical analysis. The PTFE stopcock resists a wide range of chemicals, so it suits many different titrants. It's made to standard lab tolerances for quantitative analysis.

In a school lab, a burette is used to measure and dispense variable volumes of liquid precisely, most often in titrations, where students add a solution drop by drop until a reaction is complete.

Key Specifications

  • Material: Quality borosilicate 3.3 glass, with good chemical durability and thermal shock resistance.
  • Stopcock: A straight-bore PTFE (Teflon) stopcock for smooth, leak-free control without grease.
  • Markings: High-contrast brown graduations along the tube for easy reading.
  • Maintenance: The glass body is autoclavable for high-temperature sterilisation.

Recommended Uses

  • Educational labs: Ideal for high schools and colleges to teach titration and reading a meniscus.
  • Routine lab work: Everyday jobs like preparing non-critical solutions or mixing reagents.
  • Teaching demonstrations: For showing reactions where approximate results are fine.
  • Non-regulated industries: Practical for quality control where strict ISO or pharmaceutical standards don't apply.
  • Field labs: An affordable, durable choice for mobile or field testing, where glassware is more likely to get damaged.
