Crate for setting chemical reaction under protective gas in laboratory, has flow indicator measuring flow of contactor gas before passing into inputs of glove-box, where crate is set under vacuum before protective gas achieves certain level

摘要

The crate has a flow indicator that measures flow of contactor gas before passing into inputs of a given glove-box. Additional side openings with different sizes are formed at automatic back closure of the crate in order to enable withdrawal of desired tools. The apertures in the glove are sealable by plastic sealings, where the apertures for the gloves are assisted by a suitable flap. The contactor gas is passed into output valves for safety purpose, where the crate is set under vacuum before the protective gas achieves a certain level.
