A cassette is provided which includes a combinatorial chemistry dish as used in chemical and biological laboratory work. The cassette includes a metal housing which is adjustable in that it can securely seal a variety of combinatorial dishes having different heights which contain liquid reagents. Planar inner seals placed against the dishes prevent leakage of the reagents while mixing and handling.

Combinatorial chemistry cassette

A gasoline service station includes gasoline dispensers and a PIN pad including keypads for receiving personal identification numbers and assembled into a network for securely communicating personal identification numbers from the PIN pads and dispensers to a host computer over unsecured data lines. The PIN pads and dispensers each include means for encryption and outputting of personal identification numbers. A security module includes means for decryption of data associated with each PIN pad and dispenser in a process for the respective PIN pads and dispensers and means for encryption of data associated with the host computer in a process which is different from its decryption of data associated with the PIN pads and dispensers. A site controller, which is not secure from unauthorized signal detection, has means for directing encrypted data received from the PIN pads and the dispensers to the security module and from the security module to the dispensers or the host computer as needed for properly directing encrypted data to a desired destination.

Security apparatus and system for retail environments

A laboratory container rolling device is provided which has a relatively low profile for use in confined spaces such as in refrigerators, ovens or other small compartments. Removable rollers allow the device to accommodate various diameter containers and the variable speed feature accommodates precise speed setting. Safeguards are provided to prevent container damage during extended usage to maintain the container properly upon the rollers.
