• Gas-tight, height adjustable plunger assembly for low-volume respiration or gas-phase assays
• Cast acrylic construction provides good visibility and uniform illumination of samples
• Ideal electrode chamber for teaching purposes with all the functionality of research equipment
• Variable volume reaction chamber between 0.2 and 2.5ml
• Base mounted S1 oxygen sensor forming the floor of the borosilicate glass reaction chamber
• Water jacket for effective temperature control of the sample

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

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 oxygen electrode chamber 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
