Oval Longitudinal Sight Glass Type 336 - PN 6
The glass material we use is industry proven borosilicate glass similar to DIN7081. Borosilicate glass is already highly resistant to most acids in its original state, but should strong alkaline media be present, it is possible to use one of our custom-made mica or FEP shields to protect the glass surface.
