Are you looking for a simple-to-use unit of the highest top quality which offers consistently reliable measuring results and a high degree of user comfort? Thermo Scientific Finnpipette Dispenser enables the realization of simple, rapid dispensing with sure results and is equipped with the unique combination of a ceramic piston, graduated gauge, and digital volumetric adjustment devic



The ceramic piston is manufactured from extremely hard, maximum-purity aluminium oxide ceramic and inserted in to the DURAN® glass cylinder with micrometer accuracy, forming a complete seal.

Precision replaces visual assessment

The digital engaging volumetric adjustment device ensures rapid, consistent, and totally reliable setting of the desired volume.

Ergonomic perfection

Attention to detail, both during aspirating and dispensing the medium, is supported by the ergonomically designed handle, enabling safe and fatigue-free working.

Tailored results with the suction hose

Perfection, right down to the last detail. The sturdy suction hose is not simply pushed onto the receiver, but rather twisted firmly to the unit. This prevents the formation of air bubbles during the suction.

Absolute reproducibility

The graduated gauge means that perfect reproducibility is ensured during work. A volume which has already been selected can be reset and is always identical to the previous setting. Recalibration is absolutely unnecessary.


From 0.2 ml to 60 ml.

High quality

Medium-conveying components exhibit the highest degree of chemical and thermal resistance.


Individual certificate of quality with conformity declaration.

User friendly

The complete unit can be sterilised with steam at 121° C without dismantling. Valves can be detached in a second.

Perfection of detail

Closure cap for dispensing head, threaded suction hose.
