Abstract

There is described a porous body for the storage and regulated release of vaporizable substances, which consists of open-pored sintered glass. The body preferably has a pore volume of from 30% to 85% and a mean pore size of from 10 to 350 .mu.m. The body is inert to the stored substances, has a very high storage volume and releases the stored substances very uniformly, and in particular, with no chromatography effects occurring.
