The Thermo Scientific™ Finnpipette™ Dispenser is a premium liquid handling instrument designed for the absolute precision required in high-stakes research and clinical diagnostics. Engineered with a superior chemical path that is nearly universally resistant, this bottle-top dispenser allows for the accurate delivery of reagents directly from storage reservoirs. The Finnpipette™ series is renowned for its exceptional ergonomics, featuring a smooth-action plunger that requires minimal effort, significantly reducing repetitive strain for laboratory technicians. Its robust construction ensures consistent performance even when handling volatile organic solvents or highly concentrated acids.
Built with a focus on safety, the Thermo Scientific™ Finnpipette™ Dispenser includes a specialized discharge valve mechanism that prevents accidental leakage and dripping. The clear, easy-to-read volume scale allows for rapid adjustments, while the locking nut guarantees that volumes do not shift during high-speed, repetitive dispensing cycles. Fully autoclavable and easy to calibrate, this dispenser is a reliable asset for pharmaceutical QC, environmental analysis, and molecular biology workflows where contamination control and accuracy are non-negotiable.

Professional FAQs
1. Is the Finnpipette™ Dispenser compatible with concentrated Nitric Acid?
Yes, the high-purity ceramic and PTFE internal components are designed to withstand concentrated acids, including Nitric and Hydrochloric acids.
2. How often should the dispenser be calibrated?
For ISO-certified labs, we recommend a gravimetric calibration check every 6 to 12 months depending on the frequency of use.
3. Can I dispense light-sensitive liquids with this unit?
While the standard cylinder is clear, the unit can be used with amber storage bottles to protect the reagent from UV exposure.
4. What is the benefit of the positive displacement piston?
It ensures that no air is trapped in the chamber, allowing for the accurate dispensing of high-viscosity or high-density liquids.
