WHAT'S POSITIVE ABOUT THE POSITIVE DISPLACEMENT L I MICROPIPETTOR? TOTAL DELIVERYWITH PLASTIC SNAftON,SNAP-OFF TIPS.
L/l Micropipettors are unaffected by density, viscosity, and surface tension. That's because our positive displacement micropipettor eliminates elastic air and forces all of the reagent out of the tip. (Air displacement micropipettors are subject to drainage, surface tension and density error because air is elastic.) So for precise results, the choice is obvious: L/l positive displacement micropipettors! Features and Facts about L/l fixed and adjustable volume micropipettors: • Snap-on, snap-off precision plastic tips are disposable or reusable · Accuracy and reproducibility range from 1.5% at 5 microliters to 0.5% at 1,000 microliters · All models are completely self-contained with calibration rod stored in handle · An accessory allows repetitive dispensing from reagent container.
L/l color-coded fixed volume models cover 5 to 1000 microliters. All models $37.50.
