Chemglass Life Sciences Macrotube Centrifuge Tube, 5 mL Volume, Polypropylene Tube, RCF Rating: 25000 g, Sterile/Non-Sterile: Non-Sterile, 54 mm H, 16.5 mm OD. Our new 5 mL MacroTubes take all of 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. The cap is designed to provide a secure seal from -86 to 80 deg 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 min. At temperatures above 80 deg C, the use of the CapLock Clip is recommended. The center of the cap also has a special thin "membrane" (non-resalable) area that is designed for easy puncture and access by a syringe/needle. Once punctured, the opening can also be useful for venting the internal pressure caused by incubation at moderately high temperatures. The potential contamination of pipettor shafts is greatly reduced because the 56 mm total tube length (versus 120 mm for standard 15 mL centrifuge tubes) is short enough for standard 1 or 5 mL tips to reach the tubes conical bottom. - CHMGLS
