  • Floatable laboratory tube holder
    Patent number: 5114680
    Abstract: Laboratory tube, particularly centrifuge tube holders which float in water and have end members which can be pivoted between a substantially vertical lower position and a substantially vertical upper position in about 90 degree increments. In their lower position, the members serve as legs, while in an intermediate position, storage is facilitated. When in the upper position, the end members serve as handles and may be designed to lock in place an insert that prevents lids of the centrifuge tubes from inadvertently opening.
