R C A Electron M i c r o s c o p e P r o v i d e s National Aluminate Corporation with the Satisfactory W a y to M e a s u r e S i z e of S i l i c a Particles in " N a l c o a g . " * S/7/ca particles in "Nalcoag."

Magnification

65,000X.

The effects of various particle sizes in this product's stability and performance were known. But, until the RCA Electron Microscope was used, there was no satisfactory method of measuring the size of the particles. Now, with the electron microscope it's easy! And "Nalcoag" can be produced in the particle size most suitable for the use intended. This is a product improvement directly traceable to microscope studies. The RCA Electron Microscope is also used by this company for other particle size determination, for studies of diesel fuel and miscellaneous research. Hundreds of RCA Electron Microscopes are already in use. They have opened many new avenues of exploration in the field of chemistry, metallurgy, medicine, bacteriology and biology. The technique of operation is readily acquired by any competent technician. Compact, one-piece units, these amazing microscopes can provide useful photographic enlargements up to 300,000X.
