Abstract
A locking microcentrifuge tube (10) is provided which is capable of being sealed in either of two manners, one being a friction-fit seal which is easily opened and the other being a "locked" seal for higher stress applications. The tube body (12) is adapted to mate with the cap (14) at an aperture (24) such that the plug portion (36) of the cap (14) and the aperture (24) form the friction-fit seal at the early stages of insertion. A collar (26) is provided about the aperture (24) on the tube body (12). The collar (26) is formed to include one or more circumferential projections (28, 30). The cap (14) is formed to include depressions (32, 34) adapted to mate with the projections (28, 30) upon full insertion of the plug portion (36) to create the "locked" seal. The cap (14) is secured to the tube body (12) by a hinge (38) and a tab (40). The primary usage of the locking microcentrifuge tube (10) is in biomedical laboratory analysis. The tube (10) may be manufactured in various volumes and shapes to adapt to different microcentrifuges and desired sample sizes.
