These PYREX® gas washing Standard Taper stoppers are replacements for the 500 mL gas washing bottles (No. 31760-500EC). Sidearm tubulations are 8mm O.D. A 40/50 Standard Taper stopper is used to seal the top to the base. This Standard Taper stopper incorporates a tube with a 20mm diameter extra coarse fritted disc as the distributor. The fritted disc provides greater efficiency and more uniform dispersion of gas bubbles for co…

These 30 mL PYREX® high form crucibles have 30mm diameter coarse porosity (40 to 60 µm) fritted discs. They are particularly adapted to analytical work where precipitates are dried to constant weight at 110°C. They are also suitable for higher temperatures, in which case it is advisable to heat in an electric furnace. Crucibles should not be subject to sudden temperature changes. In order to avoid strain, they should not be re…

This PYREX® 500 mL distilling apparatus is used for determining nitrogen in organic compounds. This assembly includes a Kjeldahl flask specifically developed for this process and a Graham condenser with 10mm O.D. tubulations. Both the digestion and distillation stages can be performed in this flask. The assembly shown is the distillation stage, where the amount of ammonia, and hence, nitrogen, is established. The inlet tube al…
