Axygen® 2mL Screw Cap Microcentrifuge Tubes With Conical Bottom & O-Ring Screw Caps
Axygen® polypropylene conical bottom screw top microcentrifuge tubes with "O" ring caps serve a broad range of laboratory needs including collection, pressing, centrifugation, long-term storage, and OEM packaging and shipping of restriction enzymes or other DNA/RNA modifying reagents. Color-coded caps provide a syringe port that is easily pierceable for radioisotope labeling and fraction collecting. The threaded O-ring design ensures a uniform closure allowing centrifugation up to 20,000g. Microcentrifuge tubes have ribs on the cap and tube to fit the AxyRack™ microtube racks to allow single handed opening and closing.
