Overview
The DW1/AD 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. However, due to the gas-tight plunger assembly, the DW1/AD lends itself particularly well to respiration assays in small sample volumes where any minute diffusion of ambient oxygen into the chamber may cause measurement artefacts. The DW1/AD is also suitable for gas-phase samples.
The DW1/AD oxygen electrode unit is constructed from clear cast acrylic providing good sample visibility & uniform illumination. Precise temperature control of the sample and electrode disc can be achieved by connecting the water jacket of the DW1/AD 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 the gas-tight adjustable plunger assembly. This plunger has a stoppered 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/AD electrode chamber allowing the dome of the disc to form the floor of the reaction vessel itself.
