In professional laboratories, condensers usually have ground glass joints for airtight connection to the vapor source and the liquid receptacle; however, flexible tubing of an appropriate material is often used instead. Synthware Snyder distillation column. In Soxhlet extraction, a hot solvent is infused onto some powdered material, such as ground seeds, to leach out some poorly soluble component; the solvent is then automatically distilled out of the resulting solution, condensed, and infused again.

Specifications Later on Alban (4) modified the procedure and reported it to be more accurate, 500mL PYREX Kuderna Danish Concentrators are supplied with Keck clamps instead of spring hooks. Interior rotating bands reach equilibrium more rapidly than standard styles. Finally, if the input to the condenser is a mixture of two or more miscible liquids (as is the case in fractional distillation), one must consider the vapor pressure and the percentage of the gas for each component, which depends on the composition of the liquid as well as its temperature; and all these parameters typically vary along the condenser.
