title: An automated system for the handling, diluting, and dispensing of formaldehyde.
abstract: Automation can be applied to the repetitive and mechanical handling, mixing, and dispensing of formaldehyde, the most common tissue fixative in routine clinical laboratory use. A closed automated system is described that aspirates 37% formaldehyde from large, commercial sized 490 pound drums at a remote location, and delivers 10% formalin in ready-to-use form at a special faucet in the histology laboratory without human intervention. In addition to economy from a decrease in personnel handling time and from purchasing formaldehyde in bulk, it decreases the exposure of laboratory personnel to formaldehyde fumes.
