Parr offers two styles of condensers for attachment to the head of a stirred reactor or pressure vessel. These can be made in various sizes to match the size of the reactor.
Straight Reflux Condenser
The reflux condenser consists of a length of tubing connected directly to the head of a vessel and equipped with a water cooling jacket. Condensed vapors are returned directly to the vessel and any noncondensable gases can be released through a needle valve at the top of the condenser. A spiral wound inner packing in the condenser ensures maximum effectiveness in a rather short length.

Reflux/Take-Off Condensers
The reflux/take-off condenser consists of a water jacketed tube, the same as described above, assembled with a receiving vessel attached to the lower end of the condenser. Any vapor, such as water from a polymerization reaction, can be condensed and collected in the receiver, from which it can be withdrawn through a bottom valve. Any noncondensable gases can be released through a needle valve at the top of the condenser. If condensate collection is not required, the receiver can be removed and the condenser can be mounted directly above the reactor for direct reflux into the vessel.
Modifications
Many users opt to install a ball valve at the head of the reactor below the condenser to use as a shut-off to the condenser. Alternate quick connect fittings are available as well as a variety of volumes for the collection vessels. For reactors with volumes of 1000 mL and greater, the heads are modified with larger connection ports to accommodate the condenser.
