The K-TPD system is basically a decomposed system consisting of 4 mL of flavouring to be supplemented with 6 mL of BIY or ZERO base.

Peculiar is the flexibility to have the same product with different concentrations, nicotine (up to 12 mg/mL) or strength, and base compositions (451 - 55 - 73), making the resulting mixture suitable for different systems.
