Widely used to concentrate samples, particularly pesticides and other pollutants prior to instrumental analysis Includes a two- or three-ball Snyder column, a flask and a spring-mounted collection tube for convenient access to samples Complete apparatus consists of a Snyder column 150 mm long (with Standard Taper 24/40 joints), a flask (with Standard Taper24/40 tops and Standard Taper19/22 lower joint) a graduated tube (with Standard Taper 19/22 joints) and two joint springs. If further concentration is desired, select a 2-Ball column (21582CO) and combine with the KD tube of your choice. The 250mL and 500mL completes include a 10mL tube. The 1000mL complete includes a 25mL tube. Jacketed Kuderna-Danish concentrator tubes circulate hot water through the jacket to boil the solvent dry during extraction/concentration. The bottom portion of the tube is never heated, so samples won't boil dry. The concentration automatically stops when the solvent sinks below the jacket. Tubes have either serrated tabulations or screw thread connections.
