| 摘要 |
An insulated container for keeping enzymes and biological materials held in microfuge tubes cold for an extended period of time which comprises a container having a central core made of metal (preferably of aluminum), which has receptacles for microfuge tubes and the container also having thermal insulation between the core and the inside surface of the container. The bottom of the container may be recessed to mitigate heat conductance from a laboratory bench top. A lid or cover which fits inside the top of the container is optional.
