A glass assembly for forming an electrochemical sensor, comprising
- a glass immersion tube,
- a glass membrane connected to a distal end of the immersion tube such that the glass which forms the immersion tube contains no lead and no lithium.
An electrochemical sensor, comprising:
- a glass assembly, a measuring electrode, and a reference electrode
- wherein the glass assembly includes:
- a glass immersion tube, and
- a glass membrane connected to a distal end of the immersion tube such that the glass which forms the immersion tube contains no lead and no lithium.
A method for producing a glass assembly, wherein the glass assembly includes a glass immersion tube and a glass membrane connected to a distal end of the immersion tube such that the glass which forms the immersion tube contains no lead and no lithium, comprising the steps of:
- lowering an immersion tube in the direction of a glass melt,
- remaining in a defined position above the glass melt,
- immersing in the glass melt,
- remaining in the glass melt so that a film forms at the immersed end, said film sealing said end,
- raising the immersion tube with a first movement profile to a first level above the glass melt,
- charging the interior of the immersion tube with a blow pressure curve as of leaving the melt so that a membrane forms from the film at the end of the immersion tube, remaining at the first level,
- further raising the immersion tube with a second movement profile to a second level above the glass melt, and
- remaining at the second level.
