Abstract

1,274,617. Indicator test strips. MERCK PATENT G.m.b.H. 4 Aug., 1970 [12 Aug., 1969], No. 37626/70. Heading B1X. An indicator test strip device comprises at least one reagent impregnated strip 1 of absorbent capillary material located between two films 2, 3, of impermeable synthetic resin at least one of which is transparent. At least one edge of the or each strip is unprotected by a film and at least one side of the strip is exposed to at least one hollow space, the space being optionally subdivided e.g. in the instance where the film 3 is castellated or sinusoidal. The strip may be covered with a hydrophobic layer. For several simultaneous determinations a plurality of strips may be joined end to end, Figs. 10, 11 (not shown). One of the films may be coloured. Examples relate to devices for detection of copper, nitrite, nickel, chloride or choline-esterase.
