How to maintain and protect the freezing point osmometer sample probe

The freezing point osmometer is mainly composed of two parts, one is a semiconductor refrigeration module and the other is a sample probe. Since the characteristics of the semiconductor determine that it does not require routine maintenance, this also means that the part is not prone to failure; however, since the sample probe is exposed outside the instrument, and the test head of the sample probe is wrapped by a glass ball A resistor that is extremely sensitive to heat, so it is extremely important to extend the life of the instrument. How to protect and maintain the sample probe is as follows:

1. It is recommended to first ask someone to be responsible for the use of the osmometer, or to test the osmotic pressure sample under the guidance of a special person.

2. A sample tube must be placed on the sample probe when testing the sample or not. This ensures that the sample tube is not exposed to the outside, thus avoiding the damage caused by direct contact.

3. When the sample probe is pressed down to the cold trap, the sample tube must be placed on the sample probe. Otherwise, the sample probe is pressed hard, and the sample probe directly contacts the bottom of the cold trap, causing the sample probe to be damaged.

4. After the instrument is turned off, press the sample probe with the empty sample tube to the cold trap to prevent damage caused by the instrument during use.

5. If there are conditions, try to require the osmometer supplier to provide a sample probe for use when providing the instrument.

6. After testing a sample, gently wipe the sample probe with a soft, non-ionic paper towel.

7. After the instrument has been used for a period of time, especially when the sample to be tested has a high viscosity, the sample probe is washed with distilled water.

8. After the instrument has tested each sample, lift the sample probe together with the sample, and then record.
