The Benchmark Scientific C1005-T5-ST 5mL is a Centrifuge Tube that takes the convenience of standard 1.5mL tubes and scales them up for larger volumes. These Benchmark Scientific C1005-T5-ST 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. In heated applications, the tube may be "boiled" for up to 10 minutes. At temperatures above 80 C, the use of the CapLock (sold separately) is recommended. The C1005-T5-ST tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase, DNase and pyrogen free. The 5mL tubes are sized to be compatible with all Benchmark and standard equipment, including centrifuges, dry bath block heaters, tube racks and thermal shakers/vortexes.

The 16 mm tube diameter is identical to the diameter of standard 15ml tubes, which ensures further compatibility with centrifuge rotors, etc. In many applications, these tubes have replaced 15ml tubes, dramatically reducing plastic waste, storage space and shipping costs.
