The Ripette® Stepper Dispenser, now available from Alpha Laboratories is the perfect tool for economical yet high performance repeat liquid dispensing.

Its lightweight but robust construction makes routine pipetting over long series easier and reduces the risk of repetitive strain injury.

Working on the principle of positive displacement, the Ripette uses disposable tips fitted with internal pistons, which make direct contact with the liquid during aspiration and dispensing. This ensures easy, safe, accurate and precise performance even with difficult sample types.

Volatile liquids are handled safely, without dripping or loss of sample through evaporation or aerosol formation. Every drop of viscous or high density liquid is dispensed and the tips prevent any contamination of the pipette.

Together with the range of Alpha Dispenser tips, Ripette offers versatile multi-dispensing of up to 40 different volumes from 1- 5000μl.

The desired dose and number of repetitions are set using the convenient adjustment wheel and a tip guide on the handle shows users the correct tip to use.

This ergonomic dispenser enables easy, single-handed operation and volume setting making it ideal for routine work. It is DIN EN ISO 86551 compliant and comes with a one year warranty.
