the new Melabs membrane osmometer The new Melabs membrane osmometer is the most versatile, simple and convenient instrument ever designed for measuring osmotic pressures of solutions of large molecules (20,000 to 1,000,000 number average ). No other membrane osmometer offers these advantages for biomedical and polymer applications: • Simplified design for easy operation and maintenance. Melabs uses a direct-reading strain gauge detection system-eliminates servo systems and air bubbles. More compact, less complex and less trouble.
No other instrument offers as many advantages for measuring molecular weights of m aero molecules: from proteins to polymers.
• Wide temperature ranges. 5° C to well over 100° C in Model CSM-2, 30° C to well over 100° C in Model CSM-1. Built-in variable temperature control over entire range in both instruments. • Wide pressure ranges. Four selectable ranges, 0-2.5 cm water, 0-10 cm water, 0-25 cm water, 0-100 cm water. • Performs equally well using water or organic solvents. Only stainless steel and the membrane contact sample. • Competitively priced. In most instances, Melabs osmometers will be
lower-priced than comparable instrumentation. Additional details: sample size, 0.5 ml. Response speed, 5-30 minutes. Accuracy, ± 0 . 5 % full scale, any range. Recorder output, 0-1 mv dc.
