Transparent, autoclavable centrifuge bottles made of polycarbonate with polypropylene screw closure. To guarantee leak-proof operation at high speeds or with hazardous substances you must use the 250- and 1000-ml sizes with Nalgene™ sealing cap assemblies.
N.B.: An adapter is needed for 250-ml bottles on Sorvall GSA rotors (see Order No. 23 87 31250).
