Abstract : The patent describes a gel-diffusion precipitate band reader used to measure the length of precipitate zones or bands. A gel tube is retained in a slotted holder by a spring clip in alignment with a viewing lens, a movable hairline structure operated by a micrometer, and an adjustable structure containing a pair of fixed hairlines. A viewing lens is located in front of the arrangement and rearwardly of the holder a fluorescent tube is mounted adjacent a backdrop carried by the movable hairline structure. It provides an accurate means to measure the length of precipitate zones or bands resulting from a serological reaction such as a precipitin reaction between antigen and antibody.
