7X cleaning solution was developed for use whenever a high degree of cleanliness is required
Test tubes, petri-dishes, flasks, cylinders, burettes, pipettes, slide cover glasses, hypodermic syringes
Whenever critical cleaning procedures are involved, the use of 7X solution is indicated
7X detergents show a broad range of application other than glassware, and have been used to clean re-usable parts of the endoscopic instruments, needles, laboratory surfaces
7x solutions are immediately and completely soluble in water at any concentration, without agitation. With normal detergents the precipitation of solids on cleaned surfaces is a major problem. The powerful dispersing agents in the 7x solutions work to reduce agglomerates to individual particles and hold them in suspension so that they are not redeposited on the surfaces being cleaned. 7x solutions contain a powerful wetting agent which will penetrate and clean minute crevices not accessible to ordinary cleaners. Laboratory equipment and glassware washed in any of the 7x solutions drain completely in a few seconds. solutions which do not drain quickly can allow molecules of solute to be deposited on the washed surface to the extent that a visible film is present. Such deposits can affect critical experimental work. 7x cleaning solutions are compatible with alkalis and acids. The pH is near normal and varies only minimally with the concentration. The neutral pH levels will not induce etching of delicate glassware, thereby reducing weight loss and premature breakage. 7x cleaning solutions are of particular value in cell culture laboratories where any trace of chemical contamination can interfere with the growth of cell cultures in tubes or flasks.
