Gas-phase leafdisc oxygen electrode unit with superior temperature control and fluorimetry port for FMS/LFO

Electrode chamber for measurement of advanced oxygen evolution/uptake assays from tissue samples of up to 10cm2 Black acetal construction with top window allowing uniform illumination of the sample area Superior temperature control of sample and electrode disc from 2 large water jackets 2 gas ports providing rapid changes in the gaseous environment above the sample Optical port for connection of external light source or sensor Fibre optic adapter to allow simultaneous fluorescence measurement using FMS fluorimeter Base mounted S1 oxygen electrode disc forming the floor of the reaction chamber The LD2/3 leaf-disc electrode chamber allows oxygen uptake / evolution measurements to be performed from leaf-discs, excised needles, algae, mosses, lichens etc with a surface area of up to 10cm2. A prepared S1 oxygen electrode disc is mounted directly below the sample chamber with the dome of the electrode forming the chamber floor. LD2/3 features an upper and lower water jacket ensuring superior temperature control of the sample and S1 electrode disc when linked to a temperature controlled circulating water bath. The leaf chamber section has 2 gas ports providing both a calibration and flow-through capability for rapid changes in the gaseous environment above the sample. An additional tapped and stoppered hole is provided for the introduction of an optional temperature sensor or similar auxiliary sensor. A clear cast acrylic top window allows illumination of the sample via the LH36/2R LED light source with 1 additional optical port provided for either additional illumination or insertion of a quantum sensor, etc. A further port is orientated more vertically towards the sample and allows the fibre optic cable from the FMS 1 and FMS 2 modulated fluorimeters to be positioned close to the sample allowing simultaneous measurement of chlorophyll fluorescence.
