Title: Multilayer analytical element for the detection of an agent in a liquid sample
Inventor: ROTHE ANSELM DR RER NAT
IPC: G01N33/66
Filed: 1982-05-03
Granted: 1985-10-17
Abstract: A test strip for analyzing a liquid sample has a carrier or handle, a slowly-absorbent layer fixed thereupon which slowly sucks up the liquid sample, a liquid impermeable layer fixer thereover, an absorbent reagent layer fixed thereover, and a mesh covering these, which mesh layer is fixed next to the slowly-absorbent layer on to the carrier. The mesh and layer portions of the test strip can thus be briefly immersed in the liquid sample with the carrier and withdrawn for observing the analyzing reaction of the reagent and liquid sample absorbed into the absorbent reagent layer through the mesh, the mesh serving to conduct excess liquid sample from the adjacent surface of the absorbent reagent layer to the still absorbent slowly-absorbent layer so that the excess liquid sample does not interfere with the observation of the reaction.
