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.
• 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.

PR1MA™ PBS [Phosphate Buffered Saline]

Common Name: Phosphate Buffered Saline
CAS Number: 7647-14-5; 7447-40-7; 7558-79-4; 7778-77-0
Solubility: Water
Storage Temp: Room Temperature

PBS, 100 ml Tablets refer to pre-weighed tablets that are used to prepare a specific volume of PBS (Phosphate Buffered Saline) solution. 

PBS is a widely used buffer solution in biological and biochemical research. PBS serves as a versatile buffer for various applications, including cell culture, immunohistochemistry, protein and nucleic acid research, and diagnostic assays. It helps maintain a stable pH and osmolarity, providing optimal conditions for biological reactions and preserving the integrity of cells and biomolecules. 

Each tablet contains pre-determined amounts of sodium chloride, sodium phosphate dibasic, and potassium phosphate monobasic. When dissolved in distilled water or a suitable solvent, the tablet dissolves, releasing the components, and instantly forms a ready-to-use PBS solution with a total volume of 100 ml.

These tablets ensure accurate and consistent preparation of PBS, eliminating the need for weighing and measuring individual components. They are designed to simplify the process and save time in laboratory workflows.
