The OX1LP-50mL Dissolved Oxygen Package includes:

• G107 Dissolved Oxygen Cuvette Electrode (50 mL)
• A231 Cuvette Electrode Amplifier
• A255 Magnetic Stirrer
• A135 Stir Bar (2) and O-Ring (2)
• A131 KCl Filling Solution
• A136 Membrane Material and Filter Paper
• 10 ft Excelon Tubing for the Water Jacket
• C410 LabPro Interface
• C901 Logger Pro Software
• C404 Customized Setup Software
• Instructor’s and Student’s Manuals

The OX1LP-50mL Dissolved Oxygen Package has features included in no other polarographic O2 monitoring system. The O2 electrode within the water-jacketed cuvette may be used for measurements of O2 consumption (or production) by biological samples or enzymatic reactions. Calibration is a simple 2-point process, and all the requirements for calibration are supplied as part of the package.

For many O2 electrodes, changing the membrane is a tedious and awkward process. Not so with Qubit Systems’s O2 electrode. The membrane is located under the cuvette, which screws onto the base plate, and requires only a few seconds to change. All materials for replacing the membrane (filter paper and membrane material) are included in the Dissolved Oxygen Package.

Using C901 Logger Pro software, the O2 electrode may be calibrated in units of mg O2/L, % dissolved O2, ppm, or whatever units are appropriate for your study. The Dissolved Oxygen Package provides excellent accuracy and a resolution of 0.1% O2 (where air saturated water = 100%). Dissolved O2 values may be expressed in any desired units (mg/L; % dissolved O2; ppm etc) based on a simple calibration procedure. The water jacket allows calibrations and experiments to be carried out at the same temperature, or a simple temperature correction can be made in software for measurements made at different temperatures.

Applications

The Dissolved Oxygen Package may be used for any application that involves measurement of O2 in aqueous solutions. It can be used in the laboratory for measurement of O2 concentrations from samples taken from rivers and lakes, or to measure O2 consumption (or production) by living organisms. The Dissolved O2 Package is a perfect complement to Qubit Systems’ Respiration, Plant CO2 Analysis and Photosynthesis Packages. While these packages are designed to measure the exchange of respiratory and photosynthetic gases in the gas phase, the O2 electrode allows similar measurements to be made on aquatic organisms, and also on isolated organelles, such as mitochondria and chloroplasts.

Experiments Include:

• Measurement of Aquatic Photosynthetic O2 Evolution
• Effect of Inhibitors on Mitochondrial Electron Transport
• Analysis of Light-dependent Chloroplast Electron Transport
• Effects of Temperature on O2 Uptake by Aquatic Animals
• Kinetics of O2-consuming Enzymes

Optional Components:

• Syringes for addition of metabolites to cuvette; (A141) 10µL, (A143) 50µL, (A145) 100µL
• S172 Thermistor to measure cuvette sample temperature
• A111 Variable halogen light source
• S141 Light sensor
