Volumes can be changed whether the piston is latched or unlatched. Turn the volume lock clockwise to prevent accidental changes to the volume setting.ĥ Example volumes for the 200 µl size are shown below. Then turn the knob slowly clockwise until the desired volume is displayed. To eliminate errors due to mechanical backlash: when setting the desired volume, first turn the knob 1 3 turn above the desired volume. Red tenths, hundredths of µl µl: All digits black whole µl µl: Red ml. The digital volume indicator is read from the top down µl: Black µl. Rotate the plunger button counter-clockwise to increase, and clockwise to decrease the volume. With the mechanism unlocked, turn Pipet-Plus so you are looking at the digital volume indicator, then rotate the plunger button to change volume. In this position the volume setting mechanism is unlocked and turns freely. Turn the volume lock counter-clockwise to the position shown at left below. lose-up of Aspiration Rate ontroller Slower Speed: viscous or shearsensitive samples Faster Speed: aqueous samples Setting Volume 1.

The volume setting can be locked or unlocked by turning the control wings. Volume Lock: The variable-resistance volume lock prevents inadvertent changes to the volume setting. Even at the fastest setting, piston speed is constrained to prevent sample splash. Aspiration Rate ontroller: 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. A light touch on the trigger release starts the pick-up stroke.
Piston Latch/Trigger Release: The patented piston latch secures the piston at the zero point. 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. These features improve precision from sample to sample and from technician to technician.
