RESEARCH GRADE STERILE CENTRIFUGE TUBES

These research grade centrifuge tubes feature a plug seal leak proof cap as well as a large write in area to identify each tube. They also have graduation marks. All of the 15 ml and 50 ml tubes are RNase, DNase and pyrogen free. The 15 ml tube dimensions are 17 mm x 120 mm long and the 50 ml tubes are 30 mm x 114 mm long. All of the caps are made of high density polyethylene.

CLINICAL GRADE 15 ml & 50 ml CENTRIFUGE TUBES

These 15 ml and 50 ml sterile polypropylene centrifuge tubes have printed graduations and are more economical than the research grade tubes. Because the caps are high density polyethylene, they are only autoclavable without the cap. The 15 ml tube dimensions are 17 mm x 120 mm long and the 50 ml tubes are 30 mm x 115 mm long. Their temperature range is -10° C to 80° C

STERLIN CENTRIFUGE TUBES

These gamma sterilized polypropylene centrifuge tubes are available 15 ml and 50 ml.  The 15 ml can handle high speed centrifugation speed of 10,000 g.  The 50 ml can handle speeds up to 6,000 g.  Both have a conical base and are clear with easy to read graduations.  The 50 ml tube is also available in a free standing form.  EPS 50 piece racks are breakable into 2 x 25 tube racks.

ROUND POLYPROPYLENE CENTRIFUGE TUBES

These polypropylene tubes can be used as test tubes.  The cost on these tubes is low enough to make them disposable.  The closure can be pressed in as a plug.  Polypropylene Tubes can withstand 3000 RPM and are autoclavable and freezable.   They are resistant to steam sterilization temperatures of 121°C.  Closures are available separately (SCI Cat.# 399355)

CENTRIFUGE TUBE PLUG CAPS

These polyethylene (PE) flanged plug caps provide exceptional leak resistance in test tubes, centrifuge tubes and round cuvettes.  They feature two flexible flanges that press firmly against the inside wall of the tubes, thereby providing better leak-resistance than standard plug caps.
