Glass Pipe—Corning

Sulfuric, hydrochloric, nitric, and acetic are only a few of the most corrosive materials PYREX pipe can handle with ease, 

Bromine, chlorine, bromlnations and chlorinations all are perfect for Cor-ning s corrosion resistant systems. 

Solutions are in contact only with PYREX Brand Pipe and virgin TFE preventing possible contamination of product. 

Low temperature can generally be handled. However, hot alkalies and hydrofluoric acid should be avoided. 

food grade phosphoric acid All chemicals In the neutral pH range

Reagent grade anhydrous lithium bromide powder (Matheson, Coleman and Bell) was used after drying in a vacuum oven at 100°-120°C. Potassium chloride (Fisher certified ACS) was dried at 110°C and used to calibrate the conductance cell. Deionized water from the laboratory supply was piped directly into a Pyrex glass still (Corning model AG-la) and distilled into a polyethylene vessel, where it was kept until needed. The specific conductance of the water was 1 X 10 6 12 1 cm-1.
