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.

Prism™ R Refrigerated Microcentrifuge

• Powerful refrigeration system, Quick-Cool to 4° C in 8 minutes
• Includes easy access rotor (24 x 1.5 mL) up to 17,135 xg
• Exceptionally quiet and compact
• Optional StripSpin™ adapter for 0.2 mL tubes and strips
• 2-year warranty

The Prism™ R refrigerated microcentrifuge is the premier model of Labnet's microcentrifuge product line. The unit features a powerful brushless motor and an intuitive control panel. 

The Prism™ R is the refrigerated microcentrifuge model that incorporates a powerful cooling system that maintains temperatures as low as -10°C and can reach 4°C in less than eight minutes. 

Speed is easily set and displayed in either rpm or rcf. Operation of the unit can be timed, continuous, or momentary using the "Quick" button. Vibration-free operation is ensured by an isolation system. In the event of a significant imbalance, the operation of the centrifuge is automatically stopped for safety. Deceleration at the end of a run is very quick but will not disrupt samples.

These microcentrifuges are supplied with a uniquely designed 24 x 1.5 / 2.0 mL rotor that allows easy access to the tops of the sample tubes. Individual tube slots in the solid aluminum rotor support tubes along their length and contain the sample in the event of tube failure. Adapters are available for smaller tubes as well as PCR strips. The rotor is seated on a tapered shaft which facilitates easy removal for cleaning and autoclaving.
