PIPETMAN L is an adjustable volume pipette that features a Gilson patented volume locking system. This GLP feature, among other features, meets the current needs of intensive pipette users who desire accuracy and precision without sacrificing comfort. 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 – a concern in some manual pipettes. PIPETMAN L boasts the most natural and patented tip ejection system that reduces forces through a pulley system offering low tip ejection forces with any brand of tip. An adjustable tip ejector button has further improved the comfort of PIPETMAN L by adapting to both right- and left-handed users. PIPETMAN L incorporates a newly engineered body yet keeps the legendary robustness, accuracy and precision of PIPETMAN Classic, and are available in 3 Starter Kits, with up to 4 pipettes included.
