Our new 5 ml MacroTubes™ take all of the conveniences of standard 1.5 ml tubes and scale 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. The cap is designed to provide a secure seal from -86°C to +80°C. CapLock Clips™ are available to maintain the integrity of the seal at extreme temperatures. In incubated/heated applications, it may be "boiled" for up to 10 minutes. At temperatures above 80°C, the use of the CapLock Clip™ is recommended.
The tubes are made of maximum clarity, low-binding virgin polypropylene are are certified RNase and DNase free. Sterile tubes are also pyrogen free. They are sized to be compatible with all Benchmark™ (USA) and standard German-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 pipettor 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 ml or 5 ml tips to reach the tube's conical bottom.
