The Oxford Lab Products AccuHelp Pipette Controller is a powerful, lightweight and an ergonomically designed pipette controller that is perfectly suited for use with all commonly used glass or plastic pipettes. The powerful yet quiet pump of the AccuHelp Controller can fill a 25 mL serological pipette in under 4 seconds. The soft grip push buttons create increased ergonomics for the user. The pipette cone is autoclavable and the safety valve and hydrophobic filters provide double protection against fluid penetration. The unit has three different speed modes – high speed, low speed and gravity drain. The pump speed can also be fine-tuned by varying the finger pressure on the operating knobs for better control of speed.
