SUMMARY: An improved ion‐exchange column for producing stable silica sols is described. Best results were obtained with a sulphonic‐polystyrene resin. The storage life of sols so produced may be extended to as much as two months by refrigeration and acidification with hydrochloric acid. Silica sol has a buffering action in the region of pH 2. Silica gel media prepared from such sols are comparable in cost with agar media.
