Centrifuge Tubes

Manufactured using high-purity, virgin USP Class VI Medical grade polypropylene, these centrifuge tubes are free from natural rubber and heavy metal and conform to US FDA 21 CFR. Include leak-proof threaded HDPE caps that are free of added colorings and trace metals. A large, white marking spot allows you to easily label samples. MaxiRCF™ Trace Metal-Free Centrifuge Tubes with 20,000 x g maximum RCF work well for any high-density gradient separation. They are specifically manufactured to ensure that common trace metals and elements that can interfere with experiments are below an ICP-MS detection level of one part per billion (< 1ppb). Metals included in testing are: Zinc, Boron, Iron, Copper, Manganese, Aluminum, Silicon, Nickel, Vanadium, Phosphorous, Cobalt, Chromium, Lithium, Selenium, Cadmium, Mercury, Arsenic and Lead. Available in sterile and non-sterile versions. Sterile versions are validated according to ISO 11137 for SAL 10-6 and packed 25 tubes per sealed bag, 20 bags per case of 500. Non-sterile versions are bulk-packed as a case of 500 tubes. (500 per PK )

Available with standard caps for low-speed work and sealing caps for high-speed applications-sealing caps have a built-in gripper to facilitate removal from the rotor Extra thick walls for durability-resistant to most chemicals Wide mouth design makes filling and decanting easier These precision molded centrifuge bottles are available in polycarbonate or polypropylene. For low speed applications the bottles provide excellent value for large volume/large batch centrifugation procedures. Bottles with standard caps provide reliable performance up to 8250 xg in swinging bucket and fixed angle rotors. For high-speed work, the easy-to-use Noryl® (Noryl® is a registered trademark of General Electric Company) sealing caps with silicone O-rings enable leak-free processing at high centrifugal forces over long durations. Bottles must be filled to 80% of capacity. Centrifuge bottles may be autoclaved at 121ºC at 15 psi for 20 minutes. Caps should be placed on the bottles without engaging the threads. Bottles are qualified to the rated g-forces using Sorvall® (Sorvall® is a registered trademark of Kendro Laboratory Products) and Fiberlite® (Fiberlite® is a registered trademark of Piramoon Technologies Inc.) high-speed rotors, tested at 20ºC, with bottles filled to 80% of capacity. Failure to use the correct rotor cushion or adapter will shorten the life of the bottle and may prevent achievement of the maximum rated RCF and/or bottle failure. Prolonged autoclaving and reuse may cause stress cracks, crazing or bottle discoloration. (24 per CS )
