A Versatile Gas Storage Device I
During the emrse ~f gas phase reactions, it is frequently necessary to store moderate quantities of gna nuny from the vacuum line. C'ondcnmtmn of mnterlnl intu vessels uith n capacity greater than one liter, via immersion in a cold slush, can be clumsy and sometimes precarious. Use of the pictured apparatus allows adaptation of standard taper glassware of virtually any size to gas storsge. This obviates the need far m n s t ~ d i o of n specialized glassware of many sizes for limited use, and the relatively small area of the "cold finger" that must be cooled necessitates onlv small amounts of coolant.
as the internal pressure remains below one atmosphere. This system is also useful in introducing volatile liquids to the line as a gas, since the substance does not have t o be "degassed" between each introduction. It should be noted, though, that this device is not suitable for storage of pyrophoric substances for extended periods of time, due to the possibility of air leaking through the standard taper joint.
