Microliter pipettes WITOPET expert Single-Channel

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
minimum effort required when pipetting to avoid excessive strain during pipetting
simple and quick maintenance and calibration
completely autoclavable for 15 minutes at 121°C (DIN EN ISO 285)
excellent calibration stability: no recalibration is required even after multiple autoclaving

*2-10 ml version without tip ejector

Digital burette / bottle-top burette TITREX

The digital burette TITREX is ideal for a fast and sensitive titration “drop by drop”. One instrument simulates all volumes up to 99.99 ml. Moreover, titration is possible without any loss of reagent! From air-purging, necessary for a precise titration, to disassembly of the burette in the end of the titration – the reagent, that is not needed for the titration flows back into the bottle! TITREX‘s accuracy and precision are of highest quality. Our error ranges are better than those required by ISO 8655-3. The memory function allows saving of up to 1000 values, which can be transferred to a PC and read using the included software.

Your advantage at a glance:

high quality precision instrument, made in Germany
