Benchmarks 5 mL centrifuge tube takes the conveniences of standard 1.5 mL tubes and scales them up for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak-proof seal. They 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 heated applications, the tube may be boiled for up to 10 minutes. At temperatures above 80°C, the use of the CapLock is recommended.

The tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase & DNase free. Sterile (pyrogen-free) tubes are also available and packaged in bags of twenty. 5 mL tubes are sized to be compatible with all Benchmark™ 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 tubes conical bottom. Maximum centrifugal force: 25,000 x g (when properly supported in an appropriate rotor cavity)
