ASI's 5 ml centrifuge tubes take all the conveniences of standard 1.5 ml tubes and scales them up for larger volumes. These polypropylene tubes come with an attached cap that not only provides a tight, leak proof seal, it can also be effortlessly opened (or closed) with one hand.

In incubation applications, we recommend that you use cap lock clips for incubation and boiling over 80 ˚C. When the internal pressure approaches an unsafe level, the cap partially opens, softly, in a controlled manner, releasing excess pressure, but preventing any splashing of contents. The center of cap also has a special thin 'membrane' area that is designed for easy puncture and access by a syringe/needle. Once punctured, the opening is useful for venting the internal pressure caused by incubation at moderately high temperatures. The tubes are made of maximum clarity, virgin polypropylene and are certified RNase and DNase free. Sterile tubes are also pyrogen free. They are sized to be compatible with all standard designed equipment, including centrifuges, dry bath block heaters, tube racks and thermal shakers/vortexers. The 16 mm tube diameter is identical to the diameter of standard 15 ml tubes, which ensures further compatibility with centrifuge rotors, etc. In many applications, these tubes have replaced 15 ml tubes, dramatically reducing plastic waste, storage space and shipping costs. The potential contamination of pipettetetor shafts is greatly reduced because the 56 mm total tube length (vs. 120 mm for standard 15 ml tubes) is short enough for standard 1 or 5 ml tips to reach the tube’s conical bottom.

Dimensions: 16.5×54 mm (not including rim and cap).

Screw cap tubes are supplied with 20 mm (OD) caps that seal smoothly and completely with a 360° turn.
