The making of hermetic glass to metal seals has always been a necessary part of the Company’s activities and today a wide range of hermetic insulated lead-throughs, in both “compression” and “matched” formats, is offered. Seals are available either as standard products or are specially manufactured to individual customer design and specification. Here a design assistance service is offered to enable customers to realise their requirements in the most practical way.

An important product line for the Cathodeon company was a range of lamps for use in laboratory analytical instrumentation.
These included deuterium lamps, used as a source of light in UV-Visible Spectrometry. Another important product line was Hollow Cathode Lamps used as a source in Atomic Absorption Spectrometry. This latter product provided a range of over 150 different lamps, covering the majority of the elements of the periodic table in both data coded and multi-element variants.

Importantly Pye Unicam patented the data coding of such lamps and provided use of the patent to its sister company, Cathodeon. Although supplying many different manufacturers variants of the lamps, Cathodeon's largest customer was always Pye Unicam.
