The PIPETMAN L is an adjustable volume pipette that features a Gilson patented volume locking system which meets the needs of intensive pipette users who desire accuracy and precision.
Once you lock the thumbwheel, the operating rod is no longer in contact with the counter assembly which is responsible for changing the volume; as you pipette, the volume cannot be accidentally changed.
The perfected piston assembly drastically improves the pipetting, purge, and ejection forces.
