Description Description The instrument consists of a sturdy rack in which eighteen tubes of colored fluids are inserted into numbered positions. Empty spaces between these positions allow the placing of a tube filled with sample solution between two adjacent standards to assist in comparing colors. A panel of frosted glass behind the tubes provides a background of diffuse white light when viewing the tubes.
Description The solutions are standardized at 25°C (77°F), but color determinations made between 20°C and 30°C are substantially correct, since no appreciable change in color occurs within this range.
General Information General Information Because liquid color standards first appeared over 50 years ago many old sets are still in use whose colors do not exactly agree with each other, a brief history of the Gardner Liquid Color Standards will be helpful. In the 1920‘s, several sets of colored liquids were developed for use in describing the colors of varnishes, resin solutions and drying oils.
General Information for oils in this range. These tubes were adjusted to bring them into line with accepted usage, and a slight change was made in Tube #6 to equalize the spacing. This was published as a new method, DI544-58. However, continuing problems with production and standardization of the liquid colors at that time resulted in demand for glass disks as primary standards. The method was again revised to use glass disks whose color is specified spectrophotometrically as the primary standard.
Operation Operation Pour a sample of the test liquid into an empty color comparison tube (Catalog # CL-6756). Insert the filled tube in the space between the standards which appear closest in color to the sample. Determine if the color appears to be equal to, slightly more, or slightly less in intensity than the color of the adjoining standards. Express your conclusion numerically; i.e., if the sample appears identical to 8, give it a value of 8.
Specifications/Maintenance Specifications/Maintenance The only user-replaceable part on the Illuminated rack is the lamp. To service the lamp, first remove the power cord from the receptacle. Next, open the top cover and twist the lamp ¼ turn and lift the lamp from the end fixtures. Replace with a new lamp.
