Laboratory Water: Defining Consistency for Lab Operations

Lab workers tend to treat water systems like utility or house water—open the spout and pour it out. That is partly true, as water systems have become ultra reliable. What scientists often fail to note is how thoroughly lab operations depend on water quality. There may be some leeway in certain operations, such as cleaning glassware that will wind up in an autoclave, but even there delicate techniques such as atomic absorption and polymerase chain reaction are extremely sensitive to impurities.
