|When the needle is retracted, the septum in the BAT Filter Tip automatically reseals. The septum can be penetrated by the needle hundreds of times without loss of its self-sealing function.|
The quick connect system of BAT GMS makes possible the interconnection, temporary or permanent, between the BAT Filter Tip and the various BAT Probes such as:
| ||Accurate and reliable|
Due to the quick connect system, function control of both the various BAT Probes and the installed BAT Filter Tip can be made at any time. When needed, remedial measures can also be carried out. These features of the BAT system make, for example, possible to conduct longterm pore pressure measurements or discrete sampling of groundwater with a maintained high level of accuracy and reliability.
