Abstract: Reagent materials and associated test elements are provided. In one embodiment, a test element having dual functionality includes a first coenzyme-dependent enzyme or a substrate for the first enzyme, a second coenzyme-dependent enzyme or a substrate for the second enzyme, and a coenzyme selected from the group consisting of thio-NAD, thio-NADP, and a compound according to formula (I). In one aspect, the first analyte is hydroxybutyrate and the first enzyme is a hydroxybutyrate dehydrogenase, and the second analyte is glucose and the second enzyme is a glucose dehydrogenase or a glucose oxidase. Other aspects of the subject application are directed to unique reagent materials. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the description and drawings.

Abstract: Systems, apparatuses, techniques and processes for applying a wet film (18) to a substrate (16) using a slot die (22) are provided. In one form, the air pressure around at least a portion of the discharge end of the slot die is adjustable by the application of a vacuum force (23) in order to control the width and thickness of the wet film being applied to the substrate. In one aspect of this form, the wet film is a narrow, continuous stripe of reagent material applied to a moving web of the substrate from which a plurality of test elements will be obtained. However, different forms and applications are also envisioned.

Abstract: Se proporcionan sistemas, aparatos, técnicas y procesos para aplicar una película húmeda (18) a un substrato (16) utilizando una boquilla de ranura ancha (22). En una forma, la presión del aire alrededor de al menos una porción del extremo de descarga de la boquilla de ranura ancha es ajustable por la aplicación de una fuerza de vacío (23) para controlar el anchura y el espesor de la película húmeda que es aplicada al substrato. En un aspecto de esta forma, la película húmeda es un a tira continua, estrecha, del material del reactivo aplicado a una trama en movimiento del substrato a partir del cual será obtenida una pluralidad de elementos de prueba. Sin embargo, también están contempladas diferentes formas y aplicaciones.

Abstract: The present application concerns a reagent coating mass which can be used in slot-die-coating of flat support materials in the manufacturing processes of test strips. Advantageously, the reagent mass of the invention exhibits certain superior rheological properties such as viscosity, surface tension a nd thixotropy. The reagent typically comprises an enzyme, a redox radiator and viscosity modifiers and thickeners, eg. Xanthan gum, silica, caboxy methyl cellulose, and surfactants to yield between 70 and 130 mPa.s and a surface tension between 30 and 50 nM/m. The reagent mass is preferably used to coat thin, narrow and homogeneous stripes of reagent material onto flat web material.
