Positive Displacement Pipette Tips
Zero Cross Contamination
A positive displacement pipette tip is specifically designed to fit a positive displacement pipette. The core piston and outer capillary of each tip accurately handle liquids of varying densities and surface tensions, including viscous or sticky samples, and volatile organic liquids. Sealed at the piston-end inside the capillary, positive displacement tips protect positive displacement pipettes from cross-contamination. Pos-D syringe tips are available both sterilized and non-sterilized.
Advantages of Positive Displacement Pipette Tips
Easy Pick-up and Ejection
Capillaries and pistons are preassembled and racked. Ready-to-use Pos-D positive displacement pipette tips are clean, convenient and easy to pick up and eject.
Automated and Pre-Sterilized
To prevent contamination, Pos-D tips are robotically assembled and packaged to eliminate human contact and are E-beam sterilized for extra protection.
Easy to Use
Pos-D tips provide fast and easy capillary/piston pickup from racks with no hand-mounting required.
