Performance of Low Retention GripTips from INTEGRA

25 Aug 2020

Liquids containing detergents or other low surface tension solutions form a thin film on the inner surface of the pipette tips, leading to pipetting inaccuracy, non-repeatability and, even worse, the loss of expensive or very precious reagents and samples. To overcome this issue, INTEGRA has introduced Low Retention GripTips, which prevent low surface tension samples from spreading out across the inner wall of the tips. In this application note, INTEGRA illustrates the advantages of using Low Retention GripTips when pipetting low surface tension liquids.

GripTips for INTEGRA Pipettes

INTEGRA Biosciences

The GripTips together with VIAFLO, VOYAGER and EVOLVE pipettes from INTEGRA form an integral system. Pipette tip and pipette were designed to fit perfectly together. As a result, the loading and attachment forces of the tips could be reduced to minimize wrist related stresses. In addition, the system provides a perfect tip sealing and reliably prevents tips from accidently falling off during pipetting. Consistent and safe pipetting guaranteed! Using Low Retention GripTips from INTEGRAwith heightened hydrophobic properties prevents low surface tension samples from spreading out at the inner wall of the tips for a maximum liquid recovery. Available in five volumes (12.5 µl to 5000 µl) GripTips come in bulk or stackable boxes (non-sterile, sterile and filtered) featuring colour-coded inserts that correspond to the volume ranges of the INTEGRA pipettes. The 12.5 µl and 125 µl GripTips come in 384-fold configuration, so the same tips and boxes can be used with 16-channel pipettes as well. The GREEN CHOICE is an environmentally friendly packaging of GripTips. Each GREEN CHOICE contains five GripTip inserts of non-sterile or pre-sterilized GripTips to refill the current tip boxes. Features and benefits: GripTips snap onto the tip fitting of INTEGRA pipettes, which prevents tips from falling off. Reduced tip attachment and ejection forces for comfortable, stress-free pipetting. Precise and consistent tip seal ensures that all tips on a multichannel pipette are precisely at an identical height for reliable touch offs and consistent pipetting results.
