Glass Joints

Modified Dean-Stark trap allows for more efficient cooling and separation of the azeotrope during distillation. Graduated from 0 to 10ml in 0.2mL subdivisions. **Design suggested by Dr. Craig Merlic, University of California, Los Angeles, California

The 135&deg angle between the center line of the condenser and the receiver tubes allows the distillate to fall directly into the receiver tubes. This receiver can be used with short path style distilling heads.

Cow type design has three receivers 45&deg apart. Condensers with lower drip tip inner joints will protrude into the spherical section, permitting the distillate to fall directly into the receiving flasks.

Similar to CG-1279 but with the top outer joint vertical instead of a 105&deg angle. Complete item consists of a vacuum adapter, distribution adapter, four of the listed size flasks with hooks and ten CG-110 stainless steel springs.

Barrett style distilling receiver used to determine the water content in petroleum or bituminous material. Receiver is made according to ASTM specifications, with the addition of the top outer standard taper joint and lower stopcock.

Similar to CG-1261 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.

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.

Cow type design has three receivers 45&deg apart. Condensers with lower drip tip inner joints will protrude into the spherical section, permitting the distillate to fall directly into the receiving flasks.

Graduated distillation receiver with a 4mm three way stopcock to permit solvent removal through the 10mm O.D. tube or return to distillation flask. Upper sampling port has a 2mm PTFE stopcock. The top outer and lower inner joints are the same size.

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.

Barrett style distilling receiver used to determine the water content in petroleum or bituminous material. Receiver is made according to ASTM specifications, with the addition of the top outer standard taper joint and lower stopcock.

Cow type reciever has a single standard taper outer joint at the top. The four lower graduated receiver tubes can be accessed via a syringe for product recovery. Tubes are graduated from 0 to 3mL in 0.2mL subdivisions.
