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 20000×g. Microcentrifuge tubes have ribs on the cap and tube to fit the Axyrack™ Microtube Racks to allow single-handed opening and closing. Polypropylene tubes are certified RNase-, DNase-, and pyrogen-free.
