Fisherbrand Serological Pipet Glass 2 ml Pack of 24 Pipettes

Fisherbrand 13-675H Serological Pipet – 2 mL, Borosilicate Glass, Reusable

The Fisherbrand 13-675H is a precision-engineered reusable serological pipet designed for the accurate measurement and transfer of liquids in demanding laboratory environments. Manufactured from high-quality Type I Class A borosilicate glass, this pipet offers exceptional thermal stability and superior resistance to chemical attack from acids, alkalis, and organic solvents. Each pipet is calibrated "To Deliver" (TD) with a 2 mL total capacity, featuring permanent amber stain graduations that are fused into the glass to resist wear from repeated washing and sterilization cycles. These pipets are an ideal solution for analytical chemistry, volatile solvent handling, and specialized microbiology protocols where disposable plastic alternatives are chemically incompatible.

Technical Performance and Design

• Type I Borosilicate Glass: Provides the highest level of chemical durability and low coefficient of thermal expansion, ensuring that the pipet maintains its volumetric accuracy even after repeated autoclaving.

• Permanent Amber Graduations: The markings are etched and stained into the glass surface, ensuring high visibility and preventing the fade or "wash-off" common with printed markings during exposure to harsh cleaning agents.

• Calibrated "To Deliver" (TD): Precision-adjusted to account for the thin film of liquid that remains on the internal walls, ensuring that the exact volume indicated (2 mL) is dispensed into the receiving vessel.

• Long-Term Reusability: Engineered for a long service life, these pipets can be cleaned, de-pyrogenated, and sterilized multiple times, providing a cost-effective and sustainable alternative to single-use plastics.

Product Specifications

Key Benefits & Applications

• Solvent and Acid Handling: Essential for the transfer of reagents like chloroform, phenol, or concentrated acids that would dissolve or leach plasticizers from disposable polystyrene pipets.

• Analytical Chemistry: The high volumetric precision and low extractable profile of borosilicate glass make these pipets suitable for prepared standards and trace-element analysis.

• Sustainable Laboratory Practices: Helps reduce plastic waste streams in high-volume laboratories by utilizing a washable, reusable glass format for non-critical transfers.

• High-Temperature Stability: Can be sterilized via dry heat (hot air oven) at temperatures up to 180°C, a process that is required for effective de-pyrogenation of glassware.
