Abstract

A pneumatic-tube installation for posting samples of fine material comprises at least one sample despatch station for filling, sealing and despatching sample carriers, a sample receiving station for receiving, emptying and returning the sample carriers to the sample despatch station and a pneumatic tube system connecting the sample despatch and receiving stations. When a carrier arrives at the receiving station it automatically is opened, emptied, reclosed, and readied for return to the despatch station at which it automatically is conditioned to receive a fresh sample.
