Ace Glass 7485-55 Shaker Type Hydrogenation/Gas Apparatus II 120V 60Hz

Shaker Type Hydrogenation/Gas Apparatus

These shakers provide a compact, easily operated system for treating chemicals with hydrogen in the presence of a catalyst at pressures up to four atmospheres (60 psig) and temperatures to 80°C. Apparatus II is used primarily for synthesizing or modifying organic compounds by catalytic hydrogenation, reduction or condensation, but are equally suitable for other laboratory procedures in which a liquid and gas must be mixed vigorously in a glass reactor at pressures up to four atmospheres. Apparatus II features heavy walled, pressure-tested glass reaction vessels and connectors modified with state-of-the-art closures - Ace-Threds - that eliminate the use of rubber stoppers. Tubing from the gas tank can be securely held by an O-Ring compression seal in a threaded adapter that in turn seals the reaction vessel.

Two reactors are supplied with #25 Ace-Thred that accepts 7482-33 PTFE adapter (#25 to #7 Ace-Thred) or 5844-105 (#25 to 3/8" NPT). The former is for use with 5029-202 Nylon Bushing; the latter is suitable for use with 12770-27 Tubing Adapter with 3/8" NPT. Both are used to secure tubing from tank via an O-Ring compression seal. The only adjustment in Apparatus II (as opposed to the regular Parr Apparatus #3921) is the addition of an aluminum spacer-adapter, 7485-36, that threads onto the slotted bottle screw clamp located at top of the bottle guard. This adapter butts against the #25 PTFE Adapter on top of the reaction vessel, and may be purchased separately to allow use of ACE vessels with your existing Parr unit(s).
