DW2/2
Liquid-Phase Oxygen Electrode Chamber
- Electrode chamber designed for simultaneous oxygen / chlorophyll fluorescence measurements
- Black acetal construction allowing simultaneous fluorescence and dark adapted respiration assays
- 4 optical ports allow connection of one or more LH11/2R LED light sources or A8 fibre-optic cable
- Simultaneous fluorescence studies with FMS fluorimeters using appropriate interface adapter
- 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
Overview
The DW2/2 electrode system is a modified version of the DW1 electrode chamber and has been designed for use with other instruments to allow simultaneous spectroscopic and oxygen flux measurements. DW2/2 may be used in conjunction with a range of Hansatech Instruments Ltd light sources and detectors including the FMS 1 and FMS 2 modulated chlorophyll fluorescence measurement systems to monitor changes in oxygen flux and fluorescence emission.
The reaction vessel in the DW2/2 is a precision bore borosilicate glass tube with a prepared S1 oxygen electrode disc forming the floor of the reaction vessel during measurements, identical to that found in DW1. It is surrounded by a water jacket constructed from black acetal which provides the ability for dark adaptation of samples or oxygen measurement in complete darkness. There are four optical ports mounted perpendicular to the reaction vessel at right angles to one another. Light sources, fibre optic light guides and detectors may be mounted on the DW2/2 via the ports enabling spectroscopic measurements to be made.
