Thermo Scientific Nalgene 3141-0500 Centrifuge Bottle; 450 mL; PPCO; 4/Pack

Wide mouth bottles are translucent and have excellent chemical resistance. All caps are polypropylene. Sealing caps feature a retained silicone gasket. Both cap types are autoclavable. Bottle 89050-120 is graduated and designed for large volume gross separations, especially bacterial, yeast, and tissue isolations. It has smooth inner walls to reduce shearing, a modified polyphenylene-ether screw closure, and a 50-cycle life span. It meets USP VI requirements and is non-cytotoxic. Note: Before autoclaving, place cap on the container without engaging the threads. When using the 250mL bottles ( 21010-614 and 21020-028 ) with the Sorvall GSA 6-place rotor, use the white low-density polyethylene 250mL adapter ( 21020-201 ). For proper performance, fill bottles to at least 80% of the total capacity (75% for 21020-050 ).
