TPK Series

*Diese Seite ist leider nur in Englisch verfügbar.*

The TPK Series: the international flow controller standard for OINDP testing.

The TPK was developed specifically for DPI testing to USP 601, however it has one of the widest range of functionalities for testing multiple delivery devices in any lab environment. It has been used in thousands of applications, demonstrating its reliability and ease-of-use. The advanced circuitry allows for many automated features to increase testing throughput and has optional accessories that can be easily integrated to further simplify testing and electronic outputs. Although the TPK is a complex instrument, its flexible, elegant and intuitive user interface helps reduce errors and leads the analyst through testing.

The TPK Series is ELN compatible, backward compatible, and capable of performing the same functions as the BAC.
