Round-Bottom Centrifuge Tubes, Polypropylene Copolymer, NALGENE*
Heavy-duty construction for repeated autoclavability. Excellent chemical and abrasion resistance. An economical choice for refrigerated or standard centrifugation. Molded for uniform wall thickness and extra strength. PPCO has a better low-temperature rating than standard polypropylene. Also useful as test tubes. RCF ratings are based on chemical compatibility and proper rotor fit.
Note: For proper performance, fill tubes to at least 80% of the total capacity.
Ordering Information: Supplied without closures. Polypropylene closures available separately (see 21010-852 series).
