- Base mounted S1 oxygen sensor forming the floor of the borosilicate glass reaction chamber
- Water jacket for effective temperature control of the sample
Overview
The DW3 large volume electrode chamber is particularly suited to oxygen evolution / uptake measurements of macroalgae in seawater samples of between 1 – 20ml. (15-20ml if illumination is required). The square section borosilicate glass reaction vessel and quartz front window provides good optical qualities over a large surface area when illuminating the sample using the LH36/2R red LED light housing. Samples may either be in stirred suspension or in the case of laminar material, may be vertically supported and retained by the plunger assembly such that they may be fully illuminated.
A prepared S1 oxygen electrode disc is mounted beneath the reaction vessel and forms the floor of the vessel itself providing a highly sensitive and rapid response to small changes in oxygen tension within the sample. A rear optical window allows optional insertion of the fibre-optic cable from either the FMS 1 or FMS 2 pulse modulated chlorophyll fluorimeter (using DW3/FA adapter) to provide simultaneous fluorescence measurements.
