TUBE 50mL CP PRT BK

SuperClear® tubes offer you a standard of performance not available from other brands of centrifuge tubes. These tubes are made from a unique medical grade resin that is far more durable than commodity grade resins used in most other brands of tubes. This high quality resin makes it possible for you to spin these tubes at g-forces up to 233% greater than other tubes. So you can finally do those extractions you did in polycarbonate tubes before. SuperClear® tubes feature our Patented labeling spot that helps reduce smearing of lab markers at the same time it protects sample labeling from damage during storage and centrifuging. You can order these tubes with our exclusive flat cap (except 1141P73) that includes an integral molded-in elastomeric sealing ring, or a plug style cap that includes a very deep sealing area. The flat style caps can be easily labeled and are designed to allow you to seal them to an evaporation seal with ¾ turn for one-handed operation. And then a final ¼ turn will seal them liquid tight. Only SuperClear® tubes are available with the SuperSeal™ molded in elastomeric seal. We also offer a plug style cap that is perfect for use with horizontal rocker tables or extended storage. SuperClear® tubes are available in packaging styles for all your needs, including our exclusive IntegraPack® 10 tube Sterile packs, individually wrapped sterile packs, reusable polypropylene racks, Patented fiber racks, sterile bulk bags, and non-sterile bulk bags. All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 method.
