The 10x300mm PYREX® column is designed for general chromatographic column separations. The top is tooled for a No. 00 rubber stopper fit. A PTFE (Polytetrafluorethylene) Product Standard stopcock with a No. 2 plug is provided for better column control. Sealed into the column in a coarse porosity (40 to 60 µm) fritted disc. The volume below the disc is minimized to prevent mixing and to allow clear, sharp, band definition. For…

This is an efficient 250 mL PYREX® extraction apparatus for general purpose use. Consists of a Soxhlet extractor with a 24/40 inner Standard Taper joint on the bottom and a 45/50 outer Standard Taper joint on the top, a special Friedrichs condenser with a 45/50 inner Standard Taper joint on the bottom and a flask with a 24/40 outer Standard Taper joint. The condenser tubulation O.D. is 10mm. For a replacement extractor only, s…

These 12mm diameter PYREX® gas dispersion tubes have a coarse porosity (40 to 60 µm) fritted cylinder and are used to disperse or scrub gas in liquids. The size of gas bubbles depends upon the porosity of the fritted cylinder and the liquid used. The finer porosity discs give smaller bubbles, however greater gas pressure is required. The 12mm O.D. fritted cylinder permits insertion through small openings. For more information…

These 12mm diameter PYREX® gas dispersion tubes have an extra coarse porosity (170 to 220 µm) fritted disc and are used to disperse or scrub gas in liquids. The size of gas bubbles depends upon the porosity of the fritted disc and the liquid used. The finer porosity discs give smaller bubbles, however greater gas pressure is required. The 12mm O.D. fritted cylinder permits insertion through small openings. For more information…

These PYREX® gas dispersion tubes have a 30mm diameter coarse porosity (40 to 60 µm) fritted disc and are used to disperse or scrub gas in liquids. The size of gas bubbles depends upon the porosity of the fritted disc and the liquid used. The finer porosity discs give smaller bubbles, however greater gas pressure is required. Centrally located stem permits insertion through small openings. For more information on fritted produ…
