Liquid Handling
MIDSCI has a full line of liquid handling products including laboratory pipettes, pipette tips, pipettors, reagent reservoirs, aspiration systems, and pipette controllers.
Some liquid handling products are known to have safety issues and others are prone to errors that lead to poor results.
Our liquid handling products keep in mind the basics, like price and quality, but also go one step further to solve or pre-empt these and other issues researchers (and even the planet) may face.
For instance, the aspiration systems we stock are known for performance but also for safety. Our pipettor calibration service ensures reproducible results. We carry unbreakable transfer pipettes that avoid glass hazards. And we even have eco-friendly reagent reservoirs!

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.
