Low Retention GripTips now available in environmentally friendly ECO Racks

At INTEGRA, we are committed to finding eco-friendly solutions and listening to our customer feedback to ensure we deliver high quality pipette tips that can improve pipetting performance and results in the lab. This is why we have bridged the gap to make it possible for you to order your Low Retention GripTips in our ECO Racks format. Now available for 12.5, 125, 300 and 1250 μl Low Retention GripTips – in both 96 and 384 tip configurations – these racks contain 60 % less plastic, while maintaining the high standards that you expect from INTEGRA products. The ECO Racks can also be paired with our one-of-a-kind, reusable PopTop Base for the most convenient pipetting experience.

High quality pipettes and correct techniques are essential to ensure reliable and reproducible results, but the physiochemical properties of the liquid can also have a significant impact on accuracy and precision, particularly at low volumes. Using standard pipette tips made of polypropylene to pipette low surface tension liquids – such as oils or solutions containing detergents – or viscous fluids common in some biological applications can cause the tips to take on hydrophilic properties, resulting in fluid retention as the sample adheres to the inner surface of the tip. Low Retention GripTips – developed to work with our range of manual and electronic pipettes – offer an ideal solution to overcome this issue. Incorporating a unique polypropylene blend with increased hydrophobic properties, Low Retention GripTips ensure optimal liquid recovery to enhance the reproducibility of research results. We chose this blended polypropylene approach over the silicone coating techniques commonly used for low retention disposable tips as it prevents residues washing or leaching out with the sample and negatively impacting results.

Low Retention GripTips ensure optimal liquid recovery to enhance the reproducibility of research results.

Our low retention tips, like all GripTips, do not require excessive attachment and ejection forces – unlike universal pipette tips. The rim of the GripTip snaps over the lobes of the pipette, and the high lateral resistance ensures firm attachment and perfect alignment. The shoulder provides a positive stop to prevent over-tightening of the tip, meaning it can only be attached at that precise point and no further – the tip is either on or off. This design combats the common problem of leaking tips, or even tips completely falling off the pipette, regardless of how many side wall touch offs are performed.
