Translucent polypropylene copolymer centrifuge bottles have excellent chemical resistance. Bottles feature wide-mouth Polypropylene Screw Closures with silicone gasket. 250-mL bottle is rated for speeds up to 27,500 x g; 500-mL bottle is rated for speeds up to 13,700 x g. When using the 250-mL bottle in the Sorvall GSA rotor, use the NALGENE centrifuge bottle adapter (Cat. No. DS3125-0250) available separately. Before autoclaving, just set closure on top of the bottle without engaging the threads. For proper performance these bottles must be filled to 80% of the total capacity.
