Honeywell, Inc., has announced plans to relocate its Corporate Research Center in a three-story, 100,000square-foot facility in the Minneapolis suburb of Bloomington in 1971. The company has purchased the facilities of Ashland Oil & Refining Co. which Honeywell will re-equip. Honeywell has outgrown its present research center in the Minneapolis suburb of Hopkins. HARLECO presents a new lead dioxide exposure system utilizing the Huey Sulfation plate. This method surpasses the traditional lead candle, used to measure sulfur dioxide air pollution, in both economy and accuracy. To expose tho HARLECO sulfation plate, simply remove the petri dish lid and place it in a HARLECO holder, securing the plate in an upside down position. The petri dish thus serves a two-fold purpose as shelter and as a shipping container. (Reagents for turbidimetric analysis of sulfation plates, according to the Huey method, are available from HARLECO.) Completely self-contained in a plastic petri dish, the HARLECO sulfation plate eliminates the difficulties encountered in the tedious preparation of the sulfation candle, as well as the expense of a shelter for the housing of the sampler. For further information concerning this item and other items in the air and water pollution control field, write to HARLECO. Huey Sulfation Plates HARLECO Item No. 64339 ...
