PRELIMINARY-TEST REACTION VESSELS

These vessels are available at low cost for making simple and convenient preliminary tests of chemical reactions. They are available in one size (2 in. outside diameter by 1 in inside diameter by 8 in deep inside), having a capacity of approximately 103 ml., and made of the three metals specified in the table below.

The body of the vessel is bored from solid bar stock. Two flats at the bottom of the vessel permit it to be held with a wrench or a vice to facilitate removal or the head. A thermowell is not provided.

The closure is a screw-plug which is seated on a flat metallic gasket made of copper or stainless steel, depending upon the material of which the vessel is made. Copper gaskets are used on chrome vanadium steel vessels; stainless steel gaskets are used on stainless steel vessels. A threaded opening in the head and another in the bottom of the vessel are provided for connecting to 1/4-in o. d. SUPERPRESSURE TUBING . A 3/8-in or 9/16-in. tubing connection can be furnished on special order. A Pyrex test tube may by used as a liner, if desired. All openings supplied with nuts and sleeves for connecting to tubing.
