A device for colorimetric assay of at least one component in a liquid sample, which device comprises a support, a reagent layer formed on a part of one surface of the support and a sample-receiving layer which covers at least a part of the reagent layer and at least a part of the support surface, with which the timing of application of a sample on the device is automatically detected with accuracy.

Device for assay of liquid sample

A device for colorimetric assay of at least one component in a liquid sample, which device comprises a support having a through hole with an area of from 3 to 80 mm.sup.2, a transparent porous film which is provided on the support to cover the hole, a reagent layer provided on a surface of the porous film which is not contacted to the support, and a sample-holding layer which covers the reagent layer and a part of a surface of the support, whereby an amount or concentration of at least one component in the liquid sample may be easily and accurately measured.

Device and method for assay of liquid sample

An apparatus for processing sensitive materials has a tank in which film containing a sensitive material is conveyed, the film passing through a processing bath while guided by conveying rollers, and at least one wiper coming into contact with at least one of the conveying rollers facing to a film surface of the sensitive material. A flow of processing solution is produced by at least one inlet or jet in the region where contact occurs between a wiper and a conveying roller, so that any material wiped off the roller is removed away from the contacting region.
