Abstract
A flow through type glass electrode has a resin body having a hollow interior and having bores in the opposite ends thereof extending from the outside into the interior and aligned with each other, an internal electrode positioned in the interior, a straight unitary hollow glass capillary tube extending through the bores and interior and having a uniform diameter sample flow passage therethrough, sealing members in sealing engagement around the tube and in sealing engagement in the bores where the bores open into the interior, plugs closely fitted around the tube and closely fitted in the bores where the bores open out of the body and being spaced from the sealing members along the bores to define an insulating material receiving space therebetween and extending along each bore, an insulating material filling the insulating material receiving space, and an internal liquid filling the interior.
