These Kimble Disposable Conical-Bottom Centrifuge Tubes withstand centrifugation up to 2980 RCF. Tubes are plastic shrink wrapped in modular trays for cleanliness and safety. Plain-top tubes have a finished rim that fits snap closures.
Choose from two types of closures (order separately). Screw caps are manufactured from black phenolic material (wood filled) that is very resistant to the effects of temperature and steam encountered in autoclaving. They include a cemented-in, PTFE-faced rubber liner. Snap caps are white polyethylene.
