Hellma Analytics flow-through cells are tested with an inner pressure of 3 bar for leaks in the final inspection.

Lots of flow-through cells can, however, take much higher pressures; compact cells with screw connections, for example, can take a higher level and are tested with a 5 bar pressure.

For higher loads, Hellma Analytics offers flow-through cells with a glued stainless steel or PEEK pipe

With special production processes, Hellma Analytics achieves flow-through cells with a very high chemical resistance and pressure resistance.
