Combining ease of use, chemical resistance, high speed tolerance and the ability to styand unaided on a laboratory bench, the Porvair Sciences 50mL clear polypropylene (PP) self-standing centrifuge tubes are affordable and are free from DNA/RNA, DNase/RNase and Pyrogen contamination. A circular collar around the base allows the centrifuge tube to stand up on a bench without further support. A rigid, high quality screw cap forms an airtight seal that virtually eliminates all leakage when used under recommended conditions. Each centrifuge tube features black printed graduations clearly marked for ease of use. These tubes can be spun up to 9400G and will withstand repeated autoclaving at 121°C or long term storage at -20°C. For easy identification each centrifuge tube has a large white solvent resistant writing area. They are supplied in packs of 500 with inner bags of 50 either natural or sterile.
