These GripTips are manufactured from 100% virgin polypropylene under strictly controlled conditions. Without hammering, they snap onto the pipette's tip fitting, which prevents tips from loosening, leaking or falling off.

• Low retention
• Extended length design
• Tips can be autoclaved
• Manufactured from 100% virgin polypropylene under strictly controlled conditions
• These are free of RNase, DNase, pyrogens, PCR inhibitors and endotoxins

The rim of the GripTips will snap over the multi-lobes, attaching firmly. As a result, they will never accidently fall off. A shoulder provides a positive stop to prevent over-tightening of the tip. It can only be attached up to that point and no further, ensuring that all tips are at the same height. As a result, the tip is either on or off, but nothing in between.

Viscous samples, detergents and other low surface tension liquids tend to interact with standard pipette tips forming a thin liquid film on the pipette tip inner wall. This effect leads to pipetting inaccuracy and inconsistency as well as loss of precious reagents. A unique polypropylene blend is used to mold low retention GripTips with heightened hydrophobic properties. Using low retention these tips prevents low surface tension samples from spreading out and 'wetting' the inner wall of the tips, allowing them to bead-up for a maximum liquid recovery.

They feature an extended length design enabling easy access into labware types such as tubes and deep well blocks. This extended length design also reduces PCR cross contamination as the elongated tip prevents the pipette shaft from contacting the wall of the PCR tubes.

An environmentally friendly refill system allows the reuse of the current tip racks and thus reduces plastic waste by 60%. Tip racks with single inserts in 96 and 384 fold configuration. The 384 fold configuration is highly space efficient and allows tip loading with a 16-channel pipette.
