Technology

Engineered down to the last detail.

MIKROMEISTER dispenser with raised piston – the transparent precision cylinder is visible

Safety Lock

The lockable 3-way valve prevents unintended dispensing. The system can be bled without removing the unit from the bottle.

Rapid Prime

The priming system channels reagent back into the bottle during bleeding – not a drop is wasted. Safe and economical.

Fine Adjustment

Media-specific recalibration, e.g. for temperature or viscosity. The basis for proper calibration and GLP-compliant results.

Slide'n'Lock

Volume setting in seconds – quick, accurate and equally comfortable for left- and right-handed users.

Clever Piston

The unique wiping seal eliminates swelling and freezing of the piston – ideal for crystallising, viscous, foaming media and high vapour pressures.
