| 摘要 |
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 and 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. |
