PR1MA™ Low Retention Graduated Pipette Tips

PR1MA™ Pipette Tips were meticulously designed using a specially formulated NoStick® resin to provide researchers with the highest level of liquid handling performance. PR1MA™ Pipette Tips were created with the belief that when it comes to liquid handling, less is more.

• Less Fluid Retention
• Less Sample Loss
• Less Time Spent
• Less Plastic Wasted 

PR1MA™ Pipette Tips are produced under strict controls and an ISO9001-certified Quality Assurance process. They are manufactured with a state-of-the-art fully automated tip manufacturing, filtering, and inspecting which is incomparable in our industry.

Low Retention

The PR1MA™ NoStick® tips offer users an even higher degree of fluid confidence and control. The inner surface of our NoStick® tip is considerably more hydrophobic than standard industry tips enabling viscous fluids to be dispensed more completely. Less fluid retention. Less sample loss. PR1MA™ tips prove that less is more when it comes to liquid handling!

Clean Liquid Release

PR1MA™ tips are purposely designed for a much cleaner liquid release. Less time spent waiting for the final drop to fall from the end of a tip. Our thinner walls and more finely tapered tip construction will eliminate the need to touch off. Users will maintain complete fluid control working with smaller Vols, and yet will not have to compromise their pipetting accuracy or precision.

• High-clarity, virgin polypropylene meets FDA 21 CFR 177.1520 & USP Class VI.
• Proprietary NoStick® resin technology facilitates clean release. PFAS-free.
• Filtered tips have a hydrophobic HDPE barrier that won’t contaminate or impede airflow.
• For use in the pharmaceutical and food industry, and molecular biology.
• Certified free of detectable RNase, DNase, DNA, PCR inhibitors, and tested pyrogen-free. Sterile product is certified endotoxin-free.
