RAININ Pipet-Plus pipettes redefine manual pipetting. Pipet-Plus differs from conventional manual pipettes by using a latch trigger mechanism and aspiration rate controller. These features improve precision from sample to sample and from technician to technician. Designed as a system with thin-wall RAININ tips, Pipet-Plus helps reduce the risk of cumulative trauma disorders by reducing the number of thumb strokes by 50% and by using light spring and tip ejector forces.

Unique Latch-Mode holds piston at zero position until activated by trigger, eliminates blowout. Aspiration Rate Controller controls speed.

Piston Latch/Trigger Release: The patented piston latch secures the piston at the zero point. A light touch on the trigger release starts the pick-up stroke.
Aspiration Rate Controller: Pick-up stroke speed is governed by a patented aspiration rate controller that can easily be set for fast or slow operation, depending on sample viscosity. Even at the fastest setting, piston speed is constrained to prevent sample splash.
Volume Lock: The variable-resistance volume lock prevents inadvertent changes to the volume setting. The volume setting can be locked or unlocked by turning the control wings.
