Opalescent glass

Photomultipliers are used to measure the intensity of the scattered light. The output is compared to that of a second photocell located in the light trap which measures the intensity of the incident beam. In this way the ratio [J q is measured directly with built-in compensation for any variations in the source. When filters are used for measuring depolarization, their effect on the sensitivity of the photomultiplier and its output must also be considered. Instrument calibration can be accomplished using well-characterized polymer solutions, dispersions of colloidal silica, or opalescent glass as standards. [Pg.692]

The xenobiotic-related induction of the biotransformation system usually leads to an initial adaptive response hyperplasia of the SER (= smooth endoplasmic reticulum) occurs, (s. pp 55, 394, 524) (s. fig. 21.2) The cytoplasm takes on the turbid appearance of opalescent glass. These ground glass hepatocytes (s. pp 114, 396, 424) (s. figs. 5.7 22.8) are not produced by all foreign substances,... [Pg.544]

Use Vitreous enamel frits, synthetic mica, metallurgy of aluminum and magnesium, ceramics, insecticide, opalescent glass. [Pg.1031]

Use Fluoridation, laundry sours, opalescent glass, vitreous enamel frits, metallurgy (aluminum and beryllium), insecticides and rodenticides, chemical intermediate, glue, leather and wood preservative, moth repellent, manufacture of pure silicon. [Pg.1145]

USE In the manuf of opalescent glass, in porcelain enamels, in insecticides. Also used in aluminum metallurgy. Caution Strong irritant. Ingestion can cause vomiting,... [Pg.1214]

If double-beam spectrophotometers are used, a 10% Tor 1% T optical attenuator (hole sieve, grey filter, opalescent glass), or preferably the same optical arrangement (fiber optic cable, lenses, adapters, etc.) must be taken. [Pg.163]

Standard Opalescence Place 1.0 ml of a 0.05845% w/v solution of NaCI in 10 ml of dilute HN03 in a Nessler cylinder. Dilute to 50 ml with DW and add 1 ml of AgN03 solution. Stir immediately with a glass rod and allow to stand for 5 minutes. [Pg.31]

A visible sign for the phase separation is that glass exhibits increasing opalescence with increasing temperature. Because the pore sizes are regulated with the annealing temperature (at a constant time and composition) glass becomes completely opaque near the temperature limit of the miscibility gap (800 C). [Pg.41]

The phase separation producing opalescence and photosensitivity are production-created. That is, during the production of the glass, the phase separation occurs. The phase separation that occurs with pyroceramic material and Vycor requires baking the glass at high temperatures for an extended time. This elevated temperature provides the time for the molecules to align and/or separate themselves in a crystalline pattern. [Pg.6]

Transfer a 1.0-mL sample into a calibrated 10-mL glass-stoppered cylinder graduated in 0.1-mL subdivisions, and add slowly, in small portions, alcohol of the concentration specified in the monograph. Maintain the temperature at 25°, and shake the cylinder thoroughly after each addition of alcohol. When a clear solution is first obtained, record the number of mL of alcohol required. Continue the addition of the alcohol until a total of 10 mL has been added. If opalescence or... [Pg.932]

Colourless glass does not appreciably transmit radiation wavelengths below about 310 run, and amber glass does not appreciably transmit wavelengths below 400 nm. Clear glass is moreover, used to facilitate visual inspection of the infusion solutions during administration. For this same reason, in clinical practice, clear infusion bags are often preferred to opalescent polyethylene (PE) or polypropylene bottles. [Pg.400]

Uses.—Uranium compounds are produced as by-products in the extraction of radium, and are consequently available in considerable quantity. They are not, however, as yet employed in industry to any great extent. Sodium uranate, or uranium yellow, is used to a limited extent for colouring glass, to which it imparts a yellow opalescence, and in the ceramic industries, as also is the oxide UjOg in the preparation of yellow, brown, and green glazes. - Certain salts are employed... [Pg.290]
