Are possible test sessions with several samples, up to a maximum of 16.

Test Principle

Glucose and fructose react with a complex  enzyme with the consequent production of NADH. The increase in absorbance, measured at 366 nm in the end-point, is directly proportional to the concentration of the analyte.

Reagent test kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

The kit *300270 suitable for 100 tests

The kit *300265 suitable for 10 tests

The reagents have a shelf-life of 18 months.

Processing Sample

The sample must be filtered with the appropriate 0.45 μm nylon filter, before being used.
