The heart of Xtend™
The AT dissolution bath is the core module of Xtend™. Developed for both manual and automated operation, it can be seamlessly combined with other Xtend™ modules for different analytical configurations. For fully automated operation, additional functionalities such as vessel filling and cleaning have been added to the same core design.

Innovative design.
The circular bath design allows users to observe, document, and better understand the dissolution process. All vessels are 100% visible from both outside and inside the water bath. Its round shape ensures optimum water circulation for temperature homogeneity and allows easy cleaning without any corners.

Apparatus 1/2/5/6
The AT dissolution bath can be used with different compendial USP 1/2/5/6 and non-compendial apparatus types in different style vessels like mini-vessels, China vessels, and one / two liter vessels. Irrespective of the chosen setup, the unit maintains its tight assembly geometry and ease of use.

Fail-safe networking.
The EasyTouch™ controls all Xtend™ modules irrespective of the configuration and automation level of a particular system. Mounted on the AT bath, it ensures fail-safe networking and allows Xtend™ systems to run 100% independently - even if the dissolution system is operated with PC software. No data is lost in case of network interruptions.

Flexible sampling.
Different sampling options make the AT the most flexible dissolution bath on the market. Samples can be withdrawn manually or automatically using motorized lift-in/out cannulas, HollowShaft™ sampling, or stationary cannulas. Repeatable sampling positions and a wide range of filtration possibilities ensure comparability of results.

Advanced functionalities.
The AT bath can be equipped with a great variety of automation functions and monitoring options. Automatically protocol individual vessel temperatures, replace withdrawn sample volumes, return measured UV-Vis samples immediately into vessels, or add video monitoring for visual observation of the dissolution process with individual cameras.
