Multiple Analyses on a Sample

It is not necessary skilled staff nor a laboratory for the analysis.
Results are correlated with reference method results.
It is free of service and maintenance cost.
With the same analyzers you can also perform analysis of egg, tomato, vegetable purees, cheeses and fats.

Method

Test type End Point
Test time: 30 minutes
It is possible to carry out several test sessions with a maximum of 16 samples.

Test principle

p-Nitrofenilfosfato + OH-  yellow complex

Alkaline phosphatase induces the hydrolysis of p-nitrophenyl phosphate in an alkaline solution, and forms a yellow colored complex whose intensity, measured at 405 nm, is directly proportional to the concentration of ALP in the sample.

Calibration curve

The calibration curve was performed using various additions of raw milk in pasteurized milk. The values reported are correlated with those reported in the literature (“ALP testing for milk Pasteurization” Cornell University – Dairy science facts 1998).

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.

Reagent test kit *300225 suitable for 100 tests.

Reagent test kit *300228 suitable for 10 tests.

The reagents have a shelf-life of 12 months.

Sample Handling 

Sample
Use pasteurized cow milk.
