A device for use in a laboratory and operable as both a centrifuge and a magnetic stirrer includes a housing defining a cavity therein, a motor coupled to the housing, and a spindle driven by the motor and rotatable about a first axis. The device also includes a first rotor removably couplable to the spindle and configured to support at least one tube therein, and a second rotor removably couplable to the spindle and including at least one magnet. The device also includes a controller in communication with the motor and operable in a first mode of operation when the first rotor is coupled to the spindle and operable in a second mode of operation when the second rotor is coupled to the spindle.

Laboratory device

The present invention relates to a portable surge protector providing both power line and data line surge protection. The surge protector has a housing with a central opening, and an internal cavity surrounding the central opening with a peripheral opening to receive a cord. By rotation of a mounting reel, the cord moves between a nonuse, coiled position within the housing to a use extended position outside of the housing. An electrical connector is pivotally supported in the central opening housing and has at least one electrical socket and a set of electrical prongs that extend rearwardly from the socket. The connector can be rotated to a first position normal to the housing, in which the prongs and the socket are exposed for use, or to a second position parallel to the housing, in which the socket and the prongs are recessed in the central opening.
