Dialysis Cassette


Dr. Carl Clark was biochemist/immunologist working for the Pierce Chemical Co. in Rockford, Ill., running separation columns and collecting many small (2ml) fractions for dialysis. One day, while gathering slides for a talk, he realized that the dialysis membrane could be held by a slide frame. After he made a crude prototype, a company engineer helped with development, and a patent was obtained. The Pierce Slide-A-Lyzer—sometimes termed the biological "Post-It"—was soon the firm’s No.1 product.
