Instructions - Pipette Controller

The pipette controller syringe is a Hamilton Gastight® Luer Tip syringe modified with a special free-sliding, thumb-wheel plunger. The syringe is supplied with 41 mm (1-5⁄8”) of clear vinyl tubing, 3 mm ID (0.125”) x 6 mm OD (0.250”), to attach a pipette to the syringe’s luer tip. The syringe draws liquids into the pipette (liquids do not enter the syringe barrel).
