The new microlitre pipette WITOPET expert  offers comfort thanks to an ergonomic handle and effortless pipetting thanks to a smooth-running pipetting button. Its longevity is guaranteed by simple maintenance and calibration. The pipette fulfils standards such as DIN EN ISO 8655 and offers sterile handling and calibration stability, even after repeated autoclaving.

Your advantages at a glance:

• reverse pipetting for accurate and precise intake and delivery of liquids of different viscosities
• soft grip prevents heat transfer to the internal components, ensuring precise pipetting
• counter locking mechanism prevents volume changes during pipetting
• blow-out system allows every last drop to be released
• new tip cone with high mechanical strength and very good resistance to chemicals
• interchangeable drops for pipette identification
• perfected ergonomics for maximum comfort with new, ergonomic handle with soft part
• particularly light in weight and yet robust
