pen system for the detection and quantification of surface proteins and allergens

Use for testing any surface after the cleaning process and for hard-to-reach areas in complex instruments such as serrated edges or box joints.

•The system has a high absorption swab which allows the collection of samples on different types of surfaces with the same efficiency, as well as a reaction solution.
•Detection limit: 1 μg
•Sensitivity: 0.3 μg
•Qualitative analysis: When comparing the color obtained in the solution of the pencil with the reference table, a visual estimation of surface cleaning can be made.
