  • Adapters for use with manifolds such as AF-0450 through AF-0454 to permit port connection to standard rubber hose. Adapters have hooks just below the grind for use with CG-110 stainless steel springs. The 24/40 size is available with a constriction above the serrated hose connection to permit bowl…

  • Used to monitor gas flow to reactions while providing a vent to the atmosphere. Reservoir head prevents oil from being sucked back into the system. Volume below the sidearm is approx 40mL. Bubbler has an 8mm OD top and side tubulations.

  • Adapters for use with AF-0060 thru AF-0062 vacuum manifolds that permit the manifold to be utilized with a multitude of standard glassware or tubing products. The AF-0070 adapters are to be used with either a Cajon® fitting on the main ports or at the ends of the manifold with heavy wall rubber…

  • Similar to CG-1241 but with the Vigreux column vacuum jacketed to improve distillation performance.

  • With standard taper outer joint at the top, and inner joints on the bottom and sidearm, all being the same size. Inner joints are at a 75º angle to one another.

  • Adapter used for reduced pressure filtration with plain stem buchner funnels. Top is flared to accept the listed size pluro stopper. The hose connection has an O.D. of 10mm at the largest serration. ADAPTER IS NOT SUPPLIED WITH RUBBER PLURO STOPPER, See CG-1401.

  • The 135° 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. Complete receiver is supplied with distribution adapter, three 12mL receiver tubes,…

  • Adapter has a luer outer on top and a lower standard taper inner joint.

  • Adapter used for reduced pressure filtration with plain stem buchner funnels. Top has a HEAVY DUTY tooled flare to accept the listed size pluro stopper. Hose connection is 10mm OD at the largest serration. ADAPTER IS NOT SUPPLIED WITH RUBBER PLURO STOPPER. CG-1052-A-14 Accepts up to…

  • Sampling adapter for use with a 24/40 outer joint on the reaction kettle lid. Adapter is supplied complete with a 90° bore valve enabling connection to a luer type syringe for product sampling. Adapter has three inlets for use with 1/8” OD PTFE tubing or optional 5mm OD silicone septa.…

  • Inner joint with a sealed on lower tube extending 6in below the grind.

  • Used to regulate the flow of gases or liquids into reaction systems. PTFE stopcock has a bore of 2mm. Hose connection has an O.D. of 8mm at the middle serration.

  • Vacuum Adapter has a ground glass standard taper outer joint on top that provides a convenient leak free way to connect to the OP-6602, OP-6603 and OP-6604 disposable long stem filter funnels and a taper inner joint or a vial. The unique design of the long stem filter funnel and vacuum adapter…

  • Single stage oil diffusion pump useful with manifolds such as AF-0450 through AF-0454. Will provide vacuum of 10 -5 torr, at a pumping rate of approx 8L/sec. Instead of the typical internal heating coil, boiler has a round bottom for use with CG-10000-02 or CG-12000-02 100mL heating mantle. Use of…

  • Compact and simple distilling/splitter adapter for use with Chemglass process reactors. Vapor flows upward freely through the large vapors holes to the condenser. Distillate flow is directed using the valve to either the receiving flask or back to the reactor. Control valve is either a 0-4mm or a…

  • Allihn type filter tube with a 30mm O.D. disc. Height above the disc is 100mm, lower stem is 8mm O.D. x 55mm in length.
