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.

PR1MA™ Microplate Microcentrifuge

• Quickly spins down droplets in PCR plates (less than 20 seconds)
• Accepts skirted, non-skirted, standard, and most microtiter PCR plates
• 50% smaller than traditional centrifuges
• Unique rotor design prevents sample spillage 

The PR1MA™ Microplate Microcentrifuge is the first mini-sized centrifuge with a swing-out rotor for microplates. Centrifuging plates before PCR ensures all reactants are in the bottom of the wells for proper concentrations and improved yields.

The easily accessible rotor chamber includes two plate carriers that rest at a 75° angle. This allows plates to be inserted confidently without sealing tapes or caps. Upon closing the centrifuge lid, the rotor accelerates and the centrifugal force "swings" the plates into a horizontal position, concentrating any droplets on the plate walls to the well bottoms.

Accessories 

• PCRCENT-A02 - This tube adapter for the PCRCENT Plate Centrifuge holds 96 0.2 mL tubes or 8 and 12 position PCR strips. It comes 2 per pack.
• PCRCENT-DWMP - This optional rotor for the PCRCENT Plate Centrifuge has carriers for deep well plates up to 35 mm tall.

Item # PCRCENT is proudly made in the USA! Click here for more made in America products!

• Redesigned to accept two 1 L Flasks
• Increased temperature control up to 70°C 
• Instant clamp exchange with MAGic Clamp system
• Only 11 inches wide
• 2-year warranty 

The PR1MA™ Mini Incubated Shaker is the most compact shaking incubator in its class. Despite the remarkably small footprint, a large 11.5 x 9.5 In. work space accepts several platforms for use with a variety of vessels.

The standard platform (included) features a non-slip rubber-coated surface ideal for TC flasks, petri dishes, and staining trays.

The convenient MAGic CLAMP™ Platform is also available for use with Erlenmeyer flasks and test tube racks. The unique, magnetic attachment method is the easiest way to instantly change between flask clamps of different sizes.

• Digital control of temperature and CO₂
• Personal-sized, 13 x 14.5 in. footprint (20 L)
• Accepts bottles and flasks up to 2 L
• Includes 2 stainless steel shelves
• Dual beam, infrared sensor

At only 13 inches wide, the PR1MA™ Mini CO₂ Incubator is the smallest and most economical incubator for applications requiring CO₂ gas control. Its small footprint makes the incubator ideal for use inside of biological safety cabinets, isolating sensitive cultures, or for any laboratory simply trying to conserve bench space. With a thick layer of high-efficiency insulation surrounding the chamber, the incubator is also ideal for the transportation of cells. Once power has been disconnected, the incubator maintains temperature levels within 10% of the set parameter for up to 1 hour*. In addition, each model includes a 12 V vehicle power adapter for operating the instrument in a car, boat, etc.

Both temperature and CO₂ percentages are digitally adjustable and displayed in real-time on the large LED control panel. This panel also features a “Cal” function, for easy in-lab calibration of the temperature or CO₂. In addition, humidity (up to 80%) can be added to the chamber by inserting the included (stainless steel) humidity reservoir.

Despite its small size, the incubator features a relatively large 20 L chamber with the capacity for flasks and bottles up to 2 liters. Two removable, stainless-steel shelves are included. The shelves are perforated to improve airflow within the chamber.

* If disconnected from the CO₂ supply, CO₂ percentage decreases by approx. 1%/30 min.
