Using the Product

Before Each Use

1. Fill the Wells: Add 1.0 M KNO₃ solution to both the central salt bridge well and each half-cell well.
2. Soak Overnight: Let the module soak overnight to ensure the salt bridge and porous cylinders are fully saturated for optimal ion transfer.
3. Empty the Wells: Before starting the experiment, empty the KNO₃ solution from all wells to prepare them for fresh solutions.

During Use

1. Refill the Salt Bridge Well: Fill the central salt bridge well with fresh 1.0 M KNO₃ solution.
2. Prepare Electrolyte Solutions: Select and prepare the appropriate electrolyte solutions for your experiment.
3. Fill the Half-Cell Wells: Fill each half-cell well with the selected electrolyte solutions, ensuring they are filled to the overflow rim. Make sure the lower channel leading to the salt bridge is fully saturated.
4. Insert Metal Electrodes: Place the polished metal electrodes into the corresponding half-cell wells.

5. Measure Voltage: Use the Go Direct^® Voltage Probe or another measurement device to record the voltage between the half-cells and analyze the electrochemical reactions. An example of a final experimental set-up is shown in Figure 1.

After Use

1. Remove Metals: Take out the metal electrodes.
2. Dispose of Liquids: Properly dispose of all used liquids according to lab protocols.
3. Rinse the Module: Rinse all wells and components with deionized water to clean them before storage.

Care and Maintenance

The dispenser is made of polypropylene, a material known for its excellent chemical compatibility with a wide range of substances. However, it is recommended to verify the compatibility with specific chemicals before use. Always be sure to rinse thoroughly with water after each use to maintain the dispenser's longevity and performance.
