B & A expands production of pelletized
REAGENT SODIUM HYDROXIDE B&A was first to offer a special low carbonate sodium hydroxide pellet. Now, in response to increased de mand, it has installed a unique new plant a t Marcus Hook, Pa., for pro duction of its pelletized reagent grade products. H e r e the a i r is specially filtered a n d treated. H u m i d i t y a n d tem p e r a t u r e a r e precision controlled. These, plus other process techniques, keep the carbonate content to a mini m u m a n d m a i n t a i n t h e premium quality for which B&A is known. B&A offers two grades of reagent sodium hydroxide pellets: Reagent
Special "Low Carbonate" with a car bonate limit of 0.5%, a n d Reagent A.C.S. material with carbonate limit of2.0%.Both grades run consistently below these m a x i m u m established limits.They are available in 1-lb. and 5-lb. screw-cap bottles. T h e Reagent A.C.S. grade is also available in 10lb. bottles, 25-lb. drums and larger packages.
