Preserve sample integrity
The technology has been designed so that it is impossible to have leaks. The unique purged system prevent atmospheric air from entering the valve and contaminate the sample. In some applications, it also allows to keep an inert atmosphere around the sample ports.
Cross sample contamination impossible
Due to the unique purge groove system, it is impossible for one sample port to contaminate the other. The technology, by design, make it impossible to have cross port leaks.
