1. Put the host on a stable platform with no wind flow;
2. As shown in Figure 1, unscrew the two fixing screws on the back side of the instrument and remove the upper top plate
3. Install the control magnet, ring frame rod and platinum ring according to the position shown in Figure 2 (the platinum ring is inserted into the ring frame rod first, and the outer flame part of the alcohol lamp can be installed after it is burned and cleaned. Note: Keep the burn clean platinum ring out of the hands of the hands);
4. Adjust the three pins so that the upper level bubble of the sample tray is in the center, and finally put the upper top plate back to its original place and fix it with screws. Second, how to maintain.
1. When using the interfacial tension meter, try to choose a place with low humidity, ventilation and dryness, which is conducive to the heat dissipation of the instrument
2. The maintenance of the platinum ring is very important, after use, wash it repeatedly with organic solvents, and then use the alcohol lamp to bake it red repeatedly, quickly put it into clean distilled water, and clean the residual substances on the platinum ring in time to avoid the deviation of the results caused by these substances
3. After the maintenance of the sample cup, after the measurement, the sample cup should be cleaned with petroleum ether and other solvents, if the cleaning effect is not good, it can be cleaned with alcohol
4. The platinum ring of the automatic interfacial tension tester is easy to deform, in the process of use, it should be handled gently, if the ring is seriously deformed, it should be carefully shaped to the original shape before the next experiment.
3. Precautions.
Place the instrument on a stable, firm, clean, non-slip, dry, and fireproof surface or floor.
The appliance must not be placed close to a heat source.
After the measurement, the sample cup should be cleaned with a solvent such as petroleum ether, if the cleaning effect is not good, it can be cleaned with alcohol.
Platinum rings are easy to deform, in the process of use, to handle gently, if the ring deformation is serious, to carefully shape to the original shape, before the next experiment;After using the platinum ring, rinse it repeatedly with organic solvents, and then bake it red with an alcohol lamp repeatedly, and then quickly put it into clean distilled water, and clean the residues on the platinum ring in time to avoid the deviation of results caused by these substances.
If you find that the instrument has a peculiar smell or abnormal noise during use, you should cut off the power immediately.
If the instrument will not be used for a period of time, the power cord plug should be disconnected from the power supply.
