The ANKOM Positive Control Capsule Set was developed to simplify the validation test of your RF Gas Production System and provide a positive control curve for comparison within each experiment. 
The validation test familiarizes the user with the system and ensures the system and all the modules are functioning properly. ANKOM recommends running a validation test at least once per quarter by adding one BLUE capsule, one CLEAR capsule, along with 100ml of distilled water, to each RF1 bottle.
For detailed instructions about running a validation test, see ANKOM RF Service Procedure RS004.
