Inert atmosphere methods Laboratory techniques

Inert atmosphere methods. During your laboratory work you may need to carry out reactions using chemicals which are described as air sensitive or moisture sensitive. These compounds may react with water, oxygen, carbon dioxide and even nitrogen (e.g. lithium metal). The most sensitive chemicals may require special apparatus such as glove boxes ...

Inert atmosphere Inert atmosphere methods Laboratory ...

Inert atmosphere. The source of the inert atmosphere is usually a cylinder of nitrogen or argon gas under pressure, which should be placed as close to the apparatus as possible to avoid long 'runs' of connecting rubber tubing. The gas flow rate from the cylinder is controlled by the cylinder head regulating valve (Fig. 18.1).

An inert gas supply can then be piped, via the needle, into a bottle to allow the transfer of large volumes of solvent or air-sensitive reagents to the apparatus. Alternatively a balloon can be taped to a short piece of thick-walled rubber pressure tubing to provide a supply of nitrogen when withdrawing air-sensitive reagents using a syringe ...

ACTUATION OF THE INERT DIAPHRAGM BY A GRAVITY

Thus gravity should help to keep the heavy fluid away from the medulla. Presumably Schafer's method would be tried first, and the rocking apparatus only if prolonged resuscitation proved necessary. t COMMENT These two cases, and my experiments on the healthy person, show that this gravity method of actuating the inert diaphragm is effective.
