Axygen® Looped Microcentrifuge Tube Screw Caps with O-Ring

Axygen® polypropylene looped screw caps with O-ring are compatible with all Axygen® scientific screw top microcentrifuge tubes, including both skirted self-standing and non-skirted types of 0.5mL, 1.5mL, and 2mL microcentrifuge tubes. The O-ring closure is formulated and manufactured from a special compound resistant to chemicals such as anhydrous Ethyl Alcohol, Purified Ether, Hexane, Acetone, Chloroform, Acetonitrile, 40% Trifluoroacetic acid solution, and other chemicals used in most laboratories. These unique caps also have a circular loop which secures snugly over the top of the microcentrifuge tube to create a tube with an attached screw cap. This makes closing and opening the tube easier and prevents dropping caps on the laboratory floor.

Axygen® microcentrifuge tube caps have extra long lips to help protect samples and ribs to allow one hand operation. Available in sterile or non-sterile types in a wide variety of choices of colors for batch and sample separation and easy identification
