PAT-Cell-Press
The PAT-Cell-Press is the ideal, leakproof cell for pressure testing.
Our pressure test cell for the PAT series
The PAT-Cell-Press is a 3-electrode battery test cell for measuring gas evolution and pressure and drawing gas samples (option). Its advanced design includes a laser welded pressure sensor and glass-to-metal seals. The number of non-permanent seals is reduced to its minimum: a single seal between cell lid and base and a ferrule when the cell is ordered with the optional gas sample port.
Every PAT-Cell-Press is intensively tested for helium leaks to ensure the best test results. The PAT-Cell-Press can be operated directly with the PAT-Tester-x and PAT-Tester-i-16 potentiostats. If used with a third-party potentiostat, the PAT-Press-Box is required.

Frequently asked questions
How can I identify whether my PAT-Cell is suitable for use with metal seals?
The compatible cell lid for metal seals (Item name: Screw cap insulated (PAT)) can be recognized by two features. It has two holes on the top and a white or black inset made of PPS in the lid, which serves as insulation.
As the two holes can also be found on older cell lids without insulation, you should always check whether the inset is present. Non-compatible cell lids have no inset at all.
Do you always need a PAT-Press-Box to operate the PAT-Cell-Press?
The PAT-Press-Box is required to read and record the analog pressure signal of a PAT series test cell.
It is required in the following docking stations:
The following devices provide the necessary functions themselves, therefore no PAT-Press-Box is required:
Sample test results
EL-CELL offers metal sealing rings for PAT series test cells for highest demands on cell tightness. This tool kit is designed to ensure the correct installation when using these metal seals. The handy assembly block holds the cell in place, while the torque wrench allows you to close the cell cover with the recommended amount of force.
