Precision Manual Pipette Pumps

Featuring an industry-standard, color-coded scheme by volume capacity, these pumps allow busy laboratory technicians to instantly identify the correct tool for the task. The tool integrates seamlessly with both standard glass and plastic serological pipettes, ensuring high repeatability during serial dilutions or chemical transfers.

Key Functional Benefits:

• Dual-Dispensal Modes: The thumbwheel rotates smoothly backward or forward for high-accuracy, increment-by-increment aspirating or dispensing. For rapid clearing, a built-in spring-loaded quick-release lever bypasses the wheel mechanism to empty the pipette completely.
• Leak-Free Threaded Collar: Outfitted with a soft, elastic chuck inside a reinforced threaded collar. Tightening the collar grips the pipette firmly, creating an airtight seal that eliminates fluid drift, dripping, or loose-fit errors.
• Universal Instrument Compatibility: The internal chuck effortlessly accommodates a wide range of standard glass or plastic pipette mouthpieces without scratching or damaging the pipettes.
• Low-Maintenance Lifespan: The outer housing can be quickly disassembled without specialized tools, making it easy to clean internal components if accidental sample over-aspiration or cross-contamination occurs.

Tip! If you are working with high-viscosity fluids or foaming buffers, rotate the thumbwheel more slowly during fluid intake to allow structural pressure stabilization, minimizing the risk of fluid bumping into the pump's internal barrel.
