TS METER (A GOLDBERG REFRACTOM Serum, plasma or urine determinations quickly and accurately... from a single drop THE NEW AO TS METER* requires just one d r o p of sample to provide immediate, accurate determinations of total solids, specific gravity, refractive index, protein concentration or water concentration in serum, plasma and urine. MINUTE SAMPLE REQUIRED: As little as 0.02 ml . . . a single drop . . . of sample is sufficient for the most precise determinations. TEMPERATURE COMPENSATED: Unique, hermetically-sealed liquid prism eliminates error due to temperature changes. Samples, whether at body or refrigerated temperatures, can be read immediately when the ambient temperature of the instrument is between 65-95° F. URINE SPECIFIC GRAVITY: N o more "Q.N.S." reports. Ideal for pediatrics, oliguric patients and in collections from ureteral catheters. Readings are consistently obtained with a degree of accuracy, speed or reproducibility significantly better than those obtained with urinometers, the fallingdrop method or with instruments uncompensated for temperature. SERUM PROTEINS: Ideal for rapid screening of serum proteins. Samples as small as those obtained from a microhematocrit tube are ample. DIRECT READINGS: Y o u make an immediate analysis directly from the built-in scale . . . readings to 0.1 percent total solids . . . without references to graphs, tables or thermometer readings. ''Total Solids Aieter. This method of analysis using the Goldberg Refractometer was developed in close cooperation with Dr. A. V. Wolf, Head of the Department of Physiology, University of Illinois, College of Medicine, Chicago, III.
