Burette with PTFE Stopcock, Glass B
Burette with PTFE Stopcock, Glass B is a graduated, slender cylindrical tube used for the precise dispensing of liquids, primarily in titration and chemical analysis. The PTFE stopcock is resistant to a wide range of chemicals, making it suitable for various titrants. Designed to meet standard laboratory tolerances for quantitative chemical analysis.
In a school laboratory, a burette is primarily used to precisely dispense and measure variable volumes of liquids, most commonly during titration experiments. It allows students to add a solution drop-by-drop until a specific chemical reaction is complete.
Key Specifications
- Material: Constructed from high-quality borosilicate 3.3 glass, which offers superior chemical durability and thermal shock resistance.
- Stopcock: Features a straight-bore PTFE (Teflon) stopcock for smooth, leak-free control without the need for grease.
- Markings: High-contrast Brown graduations are marked along the tube for easy volume identification.
- Maintenance: The glass body is autoclavable, allowing for high-temperature sterilization.
