One Touch multichannel pipette tips are the best choice for multichannel pipetting and high throughput work. The revolutionary soft and stretchable TPE resin used in the collar creates a leak proof seal that nearly guarantees perfect performance and accuracy every time. Significantly reduces insertion forces needed to seat the pipette tip on the multichannel pipette making them easy to seal and easy to eject. One Touch multichannel pipette tips turns any pipettor an ergonomic pipettor. This soft seal design and low insertion force aids in significantly reducing pipette cone wear and erosion and prolongs the life-span of your multi-channel pipette. While the collar is made of a soft material, the remainder of the pipette tip is made from a rigid resin for a crystal-clear, straight tip. One Touch multichannel tips are graduated for volume confirmation and come in extended volume sizes that are preferred for reducing contamination. All One Touch multichannel pipette tips are certified RNase/DNase-free, non-pyrogenic and STERILE when specified.
