Pilot Plant Spans Pharmaceutical Operations —Almost any operation in pharmaceutical manufacture can be performed in this new 4 χ 9 χ 2V2-ft. pilot plant unit designed for Lakeside Laboratories, Milwaukee, by Pfaud­

ler. It can reflux, reacts distill and handle quickly a host c*f functions. High-vacuum dis­ti l lation is done at as low as 50 microns Hg absolute pressure. A l l of the equipment is made of Type 316 stainless steel-

Unusual pilot plant assembly steps up Lakeside's synthetic work "Virtually all pilot plant operations in pharmaceutical chemistry can be performed in a single new compact assembly specially designed for Lakeside Laboratories, Inc.," states Joseph N. Jacques, plant engineer.

The assembly, part of the expand­ing synthetic chemistry division, was made to Lakeside specifications by Pfaudler. It requires a floor space of only 4 feet by 9 feet by 30 inches.

It can reflux, react, distill and handle quickly a host of physical and chemical functions. The new unit is particularly noteworthy because high vacuum distillations are achieved at as low as 50 microns Hg absolute pressure.

Made entirely of Type 316 stain­less steel, it will handle most of the organics used in Lakeside's products. It is presently used for distilling N-Ethyl-3-Hydroxypiperidine.

All of the initial synthetic work is concentrated on the production of antispasmodics, produced under the

trade names of "Dactil," "Piptal," and "Cantil." The staff has found the equipment fast, versatile and easy t o manipulate, Mr. Jacques said. The unit can be used for- small—scale pilot plant operations as -well as full—scale production.

Low-cost corrosion-resistant v*Chemstors" widely used for storing organics and inorganic acids, polyvinyls, disti l led and potable water, etc. Glassed steel prevents product contamina­tion, is easy to clean. Sizes range from 750 to 35,000 gallons (above). Horizontal or vertical construction.

Test glassed steel dryer-blender obtains amazing

results for users On test at one of the leading phar­maceutical companies recently, the new Pfaudler glassed steel dryer-blender (patents applied for) came through with flying colors on several products.

The most difficult test, done first, involved a material that had the con­sistency of whipped cream. The re ­sults were amazing, and proved that one Pjaudler unit could be used to dry seven to ten different products, replacing three conventional tray dryers of 100 trays each!

Results like these speak for them­selves and in this instance the manu­facturer placed an order for a 6-ft. Pfaudler dryer-blender on the spot. You are invited to test your products in our laboratory test blender, send­ing your own men along to observe results, if desired. Or, we can arrange to send a field unit to your plant.

One of the biggest bui l t so far—255 cu. ft. Fully charged this blender weighs 20,000 lbs. Heavy-duty gear drive tumbles bucket at 8 RPM with 15 HP motor. Magnetic brake gives nstant and positive control.
