The absolutely sealed side-illuminated single-chamber photoelectrochemical cell combines a side quartz window with vacuum and a controlled gas atmosphere. The quartz light window has a light transmittance above 95% (manufacturer data). It is held by a locking ring that keeps the seal while allowing the quartz glass to be replaced quickly.

The PTFE inner core of the lid rotates 360° so the working electrode can be aligned exactly with the light window; tightening the outer POM cap then seals the cell. A sub-surface sparger is fitted; the valve connected to the sparger is the inlet.

In the absolutely sealed cell the electrodes plug into socket (jack) connections inside the lid, isolating the system completely from the outside. With valves fitted, the cell can be evacuated (below −100 kPa) or operated under slight pressure (max. 0.5 MPa, manufacturer data). The electrodes are made to fit this cell and must be ordered together with it.

The body is made of borosilicate glass 3.3, which has low thermal expansion (3.3 × 10⁻⁶ K⁻¹) and the highest resistance classes against water (HGB 1) and acids (S 1). Avoid sudden temperature differences above 120 °C to reduce the risk of breakage.

In the jacketed (double-layer) version an outer water jacket surrounds the inner cell. Water from a circulating thermostatic bath flows through the jacket via hose connections and keeps the electrolyte at a constant temperature during the measurement. Because the inner glass of the jacketed body is thinner, do not pressurize this version; vacuum and gas purging can be used.
