Dean Stark

For easy separation of water from reaction or distillation system.

PYREX®10 mL , Stark- Dean For use in the determination of water in petroleum products and bituminous materials Graduated in 1/10 mL divisions from 0 to 1 mL ; in 1/5 mL divisions from 1 to 10 mL With Standard Taper 24/40 joints; meets ASTM Standard E 123

Similar to D451414-series but with the uptake tube vacuum jacketed to improve distillation performance. The jacket eliminates the possibility of condensation or recrystallization of distillate in the sidearm. With 2mm PTFE stopcock.

With return line to allow excess solvent to return to boiling flask. Suitable for ASTM D 95 and E 123. Joints are 24/40.

Suitable for ASTM D 95 and E 123. Subdivided 0.1mL to 2.0mL and 0.2mL above 2mL.

This innovative and compact Dean-Stark receiver is designed for azeotropic distillations using solvents that are heavier than water. The solvent vapor travels through tube “A” to a condenser inserted in the top standard taper outer joint. Vapors are condensed and collected in the…

Has separate reflux overflow tube Graduated in 1/10 ml divisions from 0 to 1 mL; in 1/5 mL divisions from 1 to 10 mL With 24/40 joints; meets ASTM Standard E 123 Specialized for determination of water in emulsified asphalts With Standard Taper24/40 joints and reflux overflow…

Calibrated "to contain" at 20°C, these borosilicate glass moisture traps are used for the determination of water in various materials by distillation with an immiscible solvent. They consist of a full length Standard Taper inner joint for vapor tube connection to distilling flask and a…

Modified Dean-Stark receiver designed for solvents that are either lighter or heavier than water. The lower three-way PTFE stopcock allows for the withdraw or return of the distillate during the distillation process. With a 10/30 outer joint on the top of the vapor tube for a 3” immersion…

Dean-Stark receiver used for determining the water content of various materials. Can be used with ASTM Method D-95 along with similar ASTM methods. The 10mL size has subdivisions of 0.1 from 0 to 2mL, and 0.2 from 2 to 10mL. The 25mL size has subdivisions of 0.1 from 0 to 2mL and 0.2 from 2 to 25mL.

Similar to CG-1258 but with the addition of an overflow tube between the uptake tube and the graduated receiver.

This apparatus combines two analytical techniques, Soxhlet extraction and Dean-Stark azeotropic distillation, into a single process for the removal of water, chlorinated dibenzo-p-dioxins (CCDs) and chlorinated dibenzofurans (CDFs) from wet particulate samples. Determination of water and…

Unique adapter used in place of a Dean & Stark Moisture Test Receiver. Simply add a condenser to top standard taper outer joint, any graduated funnel from 125mL to 2000mL to bottom standard taper inner joint, attach sample flask to inner side arm joint and you have a moisture test receiver.
