Laboratory heat exchange condensers

Two-piece grease-free sublimer with a flat bottom to enable heating on a hot plate stirrer. Condenser has a large top opening for use with dry ice / acetone or liquid nitrogen.

Two piece cold trap style condenser for use with rotary evaporators. Condenser has an additional 19/38 outer joint sealed onto the condenser to allow continuous feed of volumes exceeding the capacity of the evaporating flask.

Double coil condenser for use with rotary evaporators for cooling with tap water in a diagonal position. Condenser has a 50mm O.

Jumbo Soxhlet extraction apparatus equipped with a Duran flange at the top of the extractor. Flange is formed with a groove in the flat portion of the mating surface to accept a PTFE covered silicone o-ring to permit grease free assembly.

Two piece cold trap style condenser for use with rotary evaporators. Condenser has a 50mm flange on the side, a 35/20 lower ball joint, a 19/38 stopcock plug and removable hose connections using GL-14 threads.

Manifold is a low cost solution for the concentration of product in 96, 48 or 24 well blocks. Delivers equal amounts of gas to each well to gently speed solvent evaporation.

Double coil condenser for use with rotary evaporators for cooling with tap water in a vertical position. Condenser has a 45/40 lower inner drip tip joint, a 29/32 top outer joint, and removable hose connections using GL-14 glass threads.

Two piece cold trap style condenser for use with rotary evaporators. Condenser has a 45/40 lower inner drip joint, a 19/38 stopcock plug, and removable hose connections using GL-14 threads.

Soxhlet type extraction apparatus used for continuous extraction of solids with a suitable solvent. Extractor uses paper or CG-1372 glass thimbles.

Adapter permits sublimation directly in any reaction vessel having an standard taper outer joint simply remove condenser or other apparatus from joint, insert adapter and begin. Adapter has two components, the cold finger condenser and vacuum

Allihn style reflux condenser with a standard taper outer joint at the top and a lower inner drip tip joint. Hose connections have an O.D. of 10mm at the middle serration.
