Use in The Chemical Laboratory
Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware. Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones: for example, the first salts of crown ethers (OSi(CH3)2)n (n = 6, 7) were produced by reactions resulting from contacting organolithium and organopotassium compounds with silicone greases.

Famous quotes containing the words chemical and/or laboratory:
“Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child labor, exchange information ceaselessly. They do everything but watch television.”
—Lewis Thomas (b. 1913)
“Today, each artist must undertake to invent himself, a lifelong act of creation that constitutes the essential content of the artist’s work. The meaning of art in our time flows from this function of self-creation. Art is the laboratory for making new men.”
—Harold Rosenberg (1906–1978)
