The DW1 oxygen electrode chamber provides a versatile solution to measurements of dissolved oxygen in liquid-phase. It can be used for a wide range of applications from basic teaching through to more advanced research assays.

The DW1 oxygen electrode unit is constructed from clear cast acrylic providing good sample visibility and uniform illumination. Precise temperature control of the sample and electrode disc can be achieved by connecting the water jacket of the DW1 to a thermoregulated circulating water bath. The sample is housed within a borosilicate glass reaction vessel which has a variable sample volume of between 0.2 and 2.5ml controlled by an adjustable plunger assembly. This plunger has a central precision bore allowing additions/subtractions to be made to/from the reaction mixture using a standard Hamilton type syringe. A prepared S1 electrode disc is mounted in the bottom of the DW1 electrode chamber allowing the dome of the disc to form the floor of the reaction vessel itself.

The DW1 provides a valuable, reliable tool in any laboratory where dissolved oxygen measurements are required.
