Porous discs for use in fabrication of special glass apparatus. Available in F, M, C and XC porosities. Pressure Limits: Fritted glassware is designed for low pressure vacuum filtration or gas flow. The MAX differential pressure should not exceed 15 PSI. Thermal Limits: Fritted glassware should not...

Heavy wall pressure vessels have an internal thread for use with PTFE bushings as pressure seals. The unique design allows hand tightening and loosing for easy access into the vessel. O-ring is positioned on the bushing above the thread for improved sealing. Vessels are useful for pressure reactions...

NORELL™ Standard Series™ NMR Tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A. Applications that are suited for using this type of glass are routine NMR, where samples are run under room temperatures with no thermal gradients, for auto-sampling...

Adapters are used for reduced pressure filtration with plain stem buchner funnels. Top is tooled to accept the listed size of pluro-stopper. Serrated hose connection has an O.D. of 10mm at the largest serration. FOR PLURO STOPPERS SEE CG-1401.

10mm O.D. shaft is constructed using a molding process whereas the blade is molded directly onto the PTFE coated stainless steel shaft. This makes the stirrer chemically inert, easy to clean and can be used up to 280°C. The top of the shaft has 50mm of exposed 1/4" diameter stainless steel...

Round bottom storage flask with a standard taper outer joint on the sidearm. The 50, 100 and 250mL sizes have a 0-4mm Chem-Vac™ Chem-Cap® valve while the 500 and 1000mL sizes have a 0-8mm valve size.

Used for microscale recrystallizing of small quantities of reaction product. Consists of a glass outer tube with a non-uniform grind to purposely allow leakage, and a PTFE inner plug. The PTFE inner plug fits both the 1.0ml and 2.0ml capacity outer tubes. Capacity listed is the volume of the tube...

The unique design of our Tru-Stir™ stirrer shaft coupling eliminates the need to use rubber hose or universal adapters to attach your stirrer shafts to overhead stir motors. Coupling incorporates a unique helical stainless steel spring permitting up to 1/4” of offset misalignment and...

2800mL flask with 3 baffles on the bottom surface of the flask to help oxygen transfer to the culture medium.

Heavy duty, molded TLC developing tank for use with plates up to 20 x 20 cm (8in x 8in). The weight of the tank is approximately 15 pounds and the bottom is ground to insure stability. The unique latching system holds the matching ground surfaces of the lid and tank firmly in place, enhancing the...
