Accuracy and precision are of key importance in pipetting applications. It has been demonstrated on several occasions that the best results are obtained by following the recommended pipetting techniques, and working with an optimized system where tips and pipettes have been designed to perfectly fit together.
In this context, the nature of the liquid to be pipetted and its intrinsic physicochemical properties should not be neglected. Standard polypropylene tips that provide ideal accuracy, precision and liquid recovery when pipetting water may produce significantly different results when other substances are handled. 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. Used in combination with INTEGRA's range of pipettes, this ensures optimal liquid recovery and best pipetting results. This application guide illustrates the advantages of using Low Retention GripTips when pipetting low surface tension liquids.
