Biotix 30459891 Single Channel Pipette, 0.5-10 μL, 1/pk (Rainin Alternative)

Pipetting is a highly repetitive motion which can have lasting effects on your hand, wrist and shoulder. Biotix® xPIPETTE™ is designed to improve the ergonomics of traditional pipetting systems by reducing the forces you’re exposed to during this repetitive process. The patented light force ejection system built into xTIP4 and xPIPETTE produce the lowest ejection forces on the market, reducing your risk of developing repetitive stress injuries and muscle fatigue.
Accurate, precise, and more ergonomic:

Compatible with Biotix xTIP4 and Rainin® LTS™ pipette tips.
When inserting a tip the pipette contacts the positive stop in xTIP4 pipette tips to create identical tip alignment and sealing every time
Up to 5X less ejection force than traditional pipetting systems
Low drag seals and light spring forces produce a smooth accurate draw with lighter force
Easy to reach ejector button is cushioned to reduce dynamic stresses when ejecting a tip
Volume lock ensures your measurements are accurate and precise without volume drift
Designed to be rugged and durable for long term use with a low cost of ownership
