Into a Corner Of Your Lab PORTABLE^V ELECTROPHORESIS "Produces Schlieren
Patterns
Standard equipment in almost all universities and research centers, the Portable is trouble-free and operates in all climates. Its schlieren system is temperature controlled by me chanical refrigeration.
Notice how clearly various proteins are identified on both schlieren and interference patterns in the above photograph. Test sample was hu man serum. Breakdown of compo nents shows albumin, alpha-1, alpha-2, beta, and gamma compo nents. Tracings are typical of the excellent patterns produced in the Model B, which offers capabilities for every necessary application: rapid routine analysis, preparatory work on a large scale, interferometric analysis for basic research, or specialized procedures such as diffusion or adsorption studies.
