Eppendorf™ Combitips™ Plus Pipet Tips

Positive displacement for correct volumes

Tips function according to the positive-displacement principle, ensuring that the correct volume is dispensed with regard to the density and viscosity of the liquid used. The positive displacement system provides safer dispensing of radioactive and toxic substances as well as solutions with high vapor pressure. No aerosols are formed.
  • For use with Eppendorf Repeaters™ (original, Plus, Pro, stream and Xstream); and EDOS (automatic dispensing system)
  • Available in nine volumes from 0.1 to 50mL
  • Reliable results ensured by positive-displacement system
  • Fine tip of Combitip provides exact dispensing without additional pipet tip
  • Polyethylene plunger and polypropylene cylinder make these tips ideal for use with aggressive reagents
  • Choose from sterile and nonsterile Combitips Plus Tips and Eppendorf Biopur™ tips, which are certified sterile as well as pyrogen-, RNase-, DNA-, and ATP-free
