Screw Top Microcentrifuge Tubes with Caps, Axygen Scientific
These conical-bottom screw cap microcentrifuge tubes 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 (see 10011-272 series) to allow single-handed opening and closing. Polypropylene tubes are certified RNase-, DNase-, and pyrogen-free. Tubes without ribs are also available; contact our sales representative for information.
Ordering Information: All microtubes include non-looped caps with O-rings. Presterilized microtubes are supplied with cap attached.
