Replacement vapor (steam) tube adapter for Büchi® R-200/205 rotary evaporators. Adapters have a 50mm OD top flange with a tapered interior to fit the Büchi® sealing ring. Lower portion of the adapter has the listed standard taper inner joint. Each tube is supplied complete with...

Adapter has an extra coarse disc between the serrated hose connection and the inner joint. Fritted disc prevents solids from being introduced into the system. Hose connection has an O.D. of 10mm at the largest serration.

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.

Low actinic red stained glass provides protection to light sensitive solutions. Allowing less than 1% transmission below 400nm and 5% from 400-600nm. Wide mouth design facilitates mixing, pipette access, sampling and filling. Unique Flat Bottom Interior permits the use of a standard stir bar. Large...

Heavy wall pressure vessel is the same as CG-1880, but shaped similar to a round bottom flask with a #25 internal thread for use with a PTFE bushing as a pressure seal. Complete apparatus is supplied with vessel, back seal solid PTFE bushing and viton o-ring. Other vessel sizes and safety plastic...

European squibb style separatory funnel with a PTFE stopcock. Supplied complete with a glass stopper of the listed size. For replacement stoppers see CG-3000.

Similar to CG-1192 but with a sealed in COARSE porosity fritted disc to support column packing. Column is constructed using MEDIUM WALL TUBING. Can be used as a gravity eluted column or a flash column (as described by W.C. Still, M. Kahn and A. Mitra of Columbia University in JOURNAL OF ORGANIC...

Hi-vac valve with two sidearms sealed to the barrel at a 90° angle to one another. Designed with a precision external thread for fine control.

Similar to CG-1210 but with the 24/40 outer joint replaced with a serrated hose connection for use with a drying tube. This style condenser is used primarily in Soxhlet extractions or in reflux mode. Hose connections have an O.D. of 10mm at the middle serration.

With two standard taper inner joints, parallel, and at a 75º angle to the connecting tube. Chemglass Distillation Adapters are designed to facilitate efficient distillation processes by securely connecting glassware components. These adapters are made from high-quality glass to withstand...

CLAMPS, CHAIN, 12IN EXTENSION, Similar to the CG-9220-01 except has a 12" long arm. Clamp can accommodate up to 6-1/2” (170mm) O.D. respectively. Quick slip-on chain connection has large, easy-to-turn adjusting knob. Grip is vinyl coated. VALVES, CHEM-VAC, HIGH VACUUM, LOW HOLD UP,...

Allihn style reflux condenser with a standard taper outer joint at the top and a lower inner drip tip joint. Hose connections have an O.D. of 10mm at the middle serration.

Used to connect dissimilar standard taper joint sizes. Lower inner joint is smaller in size than the top outer joint.

 These convenience kits come with 100 vials with the closures attached. Packaged in convenient vial trays.

Laboratory support jacks provide for stable height adjustment and support for items in the lab such as flasks, baths or hot plate stirrers. Top and bottom plates are constructed of anodized aluminum while the support mechanism is made of chrome plated steel.

Chem Snap Caps™ may be snapped on and off by hand which eliminates the need for metal crimping and decapping tools, thus reducing potential hazards due to sharp aluminum edges. Large opening provides greater target area for needle penetration. These liner-less Chem Snap Caps™ are...

Chemically inert and suitable for low pressure applications, FEP tubing is recommended for all connections in the high performance, low pressure liquid chromatography system. The tubing is extruded with an outer diameter tolerance of +/- .001in. The 1/8in tubing can withstand pressure up to 500 psi....

Bonded closures feature clear PTFE/Silicone liner bonded directly to the closure without the use of glue or adhesives. These bonded closures provide a cost effective, integrated, one-piece system that eliminates costly line fallout. Closures are available in both pre-slit and non-slit designs.

Main vacuum line with 4ea 24/40 inner ports (A) having a unique configuration of 0-4mm Chem-Vac Chem-Cap®; valves. The valves are sealed to either the vacuum or inert gas side of the manifold and then bent to a 90º angle, forming a strong but very compact assembly. This configuration...

FLAKE-FREE Chemically Resistant Maximum 500 RPM; Vacuum (~5 Torr) and Pressure (~3 PSI) Polymer Blend Sleeve Provides Excellent Wear Resistance For Use with Polished Glass, PTFE or Stainless Steel Stirrer Shafts Universal Chem-Vac™ PTFE stirrer bearing provides a VACUUM TIGHT FLAKE-FREE SEAL...

Cylindrical shaped tube useful for storage or simple reactions. Tube has a standard taper outer joint. Available with a choice of a 2mm high vacuum glass stopcock having a S.S. constant pressure retaining device or a 0-4mm Chem-Cap® Airfree® inlet valve.

Commercial quality ground and polished clear fused quartz. Edges have a ground finished on all sizes. 

Similar to CG-3026 and CG-3027 except with two holes. These stoppers are suitable for practically all general laboratory uses.
