• Rugged, easy to handle • Autoclavable and nonflammable • Unaffected by most chemicals Cox M-780™, a new all-purpose submicron filter medium, offers a number of operating advantages and economies over fragile, fast-clogging membranes. Physically strong and easy to handle, M-780 discs are interchangeable with other media without modification of your present membrane filter equipment. High loading capacity and throughput life. Complex three-dimensional pore struc ture presents extremely large total area for retention of contaminants. Result: Lower ΔΡ, longer throughput life, lower process costs. Nonflammable, heat-stable. No fire haz ard, no problems with high-temperature operation and sterilization. Insoluble, nontoxic. Inert to most concen trated acids, alcohols, esters, hydrocar bons, other organics.

Stays on the job The most forgettable pumps ever installed in your pilot plant, chemical processing, or laboratory equipment. With Trouble Free Performance you can install and forget. The only way an Eastern centrifugal
pump calls attention to itself is in delivering exactly the performance you need — year after year after year. Some continuous-duty pump installations by Eastern are still doing exactly that after many years of steady churning.* "Installations on request·
So: If you need flexibility and performance in centrifugal pumps with flow ranges to 70 gpm, pressures to 70 psi, write for the new catalog #140.
