These approximately 5mm PYREX® beads are useful as boiling stones, mixing beads and as packing for distillation columns. Beads are packaged in 0.45kg. (1 lb.) bottles (each bottle is one pack), which have a packing volume of approximately 360cm³ or 22 cubic inches.

These approximately 6mm PYREX® beads are useful as boiling stones, mixing beads and as packing for distillation columns. Beads are packaged in 0.45kg. (1 lb.) bottles (each bottle is one pack), which have a packing volume of approximately 360cm³ or 22 cubic inches.

These high performance Rotaflo® in-line stopcocks can be adjusted from a 0 to 10mm bore opening and have 13mm O. D. sidearms. They are designed so that only chemically resistant polytetrafluoroethylene (PTFE) and PYREX® borosilicate glass are in contact with liquids and gases. The Rotaflo® stopcock design permits fine flow adjustment. Lubrication is not required and assembly is fast because there are no O-rings, washers or nut…
