Fisher Scientific Serological Pipette Glass 10 ml Case of 500 Pipets

Fisherbrand 13-678-27F Glass Serological Pipette – 10 mL, Reusable, Color-Coded

The Fisherbrand 13-678-27F is a high-performance liquid handling tool engineered for accuracy, durability, and chemical resistance. Constructed from Type I, Class A borosilicate glass, this 10 mL pipette is designed to withstand the rigors of daily laboratory use, including repeated exposure to harsh solvents and multiple autoclave sterilization cycles. It features permanent, high-contrast amber graduations that are fired into the glass to prevent fading or wear from abrasive cleaning. Calibrated "To Deliver" (TD) with a blow-out requirement, this instrument provides precise volumetric delivery for a wide range of reagents, media, and analytical samples. The top end is fire-polished for safety and compatible with all standard pipette fillers, bulbs, and controllers. The 13-678-27F is an ideal, eco-friendly solution for labs seeking to minimize plastic waste without compromising on the chemical integrity or volumetric precision of their liquid handling workflows.

Technical Performance and Design

• Borosilicate Glass Construction: Offers superior thermal shock resistance and a low coefficient of expansion, ensuring the pipette remains dimensionally stable even after repeated heat sterilization at 121°C.

• Calibrated "To Deliver" (TD): Precision-adjusted to account for the liquid film that naturally adheres to the internal glass walls, ensuring that exactly 10 mL is dispensed when the final drop is blown out.

• Permanent Amber Graduations: Features 0.1 mL scale intervals with bold numerical markings, providing excellent legibility against both clear and colored liquids for error-free volume measurement.

• Standardized Orange Color-Coding: Features the international standard orange color band at the top, allowing for rapid size identification and organization within pipette canisters or storage racks.

Key Benefits & Applications

• Solvent Resistance: Unlike polystyrene disposables, this glass pipette will not leach plasticizers or degrade when used with alcohols, chloroform, or other organic solvents.

• Sustainable Laboratory Practices: Helps laboratories reduce their environmental footprint by replacing thousands of single-use plastic units with a single, long-lasting glass instrument.

• Consistent Volumetric Accuracy: The smooth, non-reactive glass interior ensures a consistent meniscus and clean drainage, which is critical for standardized analytical protocols.

• Versatile Utility: A staple in microbiology, clinical chemistry, and environmental testing for the large-volume transfer of stock solutions and concentrated buffers.
