Fisherbrand Serological Pipette 5 ml Borosilicate Glass Individually Wrapped 500 Pipets

Description

Fisherbrand 13-678-27E Glass Serological Pipette – 5 mL, Reusable, Color-Coded

The Fisherbrand 13-678-27E is a high-precision liquid handling instrument designed for durability and accuracy in demanding laboratory environments. Manufactured from chemically resistant borosilicate glass, this 5 mL serological pipette is engineered to withstand repeated autoclave cycles and exposure to aggressive reagents. It features permanent, easy-to-read amber or blue graduations that are fired into the glass surface to resist wear from caustic cleaning agents. Calibrated “To Deliver” (TD) with a blow-out requirement, this pipette ensures high volumetric accuracy for the transfer of media, reagents, and biological samples. The top end is specially fire-polished and designed to accept standard pipette fillers or bulbs. With its long-lasting construction and precision-tapered tip, the 13-678-27E is an eco-friendly and cost-effective alternative to single-use plastic labware for routine volumetric tasks.

Technical Performance and Design

• Borosilicate Glass Construction: Offers a low coefficient of thermal expansion and exceptional resistance to thermal shock, making it safe for repeated steam sterilization at 121°C.

• Calibrated “To Deliver” (TD): Precision-adjusted to account for the liquid film that remains on the internal glass wall, ensuring that the volume dispensed matches the scale when the tip is blown out.

• Permanent Graduations: Features 0.1 mL scale intervals with major numerical markings, ensuring error-free volume reading even after years of heavy use and industrial dishwashing.

• Standardized Blue Color-Coding: Adheres to international color-coding standards for 5 mL pipettes, allowing for rapid identification and selection from pipette racks or canisters.
