The nitrogen blower has the characteristics of time saving, convenient operation and easy control, and can quickly obtain the expected results. It is widely used in pesticide residue analysis, commodity inspection, food, environment, pharmaceutical, biological products and other industries and for sample preparation in liquid phase, gas phase and mass spectrometry analysis.
Widely used in pesticide residue analysis, pharmaceutical drug inspection, environmental analysis, biological analysis, commodity inspection, food and beverage industries.
Because the nitrogen blower needs to be soaked in the water bath during operation, it must be cleaned and maintained after use to extend the life of the instrument.
1. Choose a suitable heating medium
The heating medium uses distilled water and deionized water, which will effectively prevent scale formation on the water bath wall. Be careful not to use organic solvents as the heating medium. The volatilization of organic solutes is toxic and will harm human health.
2. Use algaecide to purify the water bath
After the test is completed, the algaecide is added to the water of the water bath when it is not heated to prevent the organisms in the water bath from being contaminated. When selecting an algaecide, make sure that the algaecide used does not affect the properties of the sample to be processed, and that no acidic algaecide should be used.
3. Regular water changes
Impurities from long-term experiments, as well as pollutants in the air will pollute the water quality, not only will produce scale, but also may affect the accuracy and rate of the experiment. Therefore, it is recommended that the water in the water bath be changed once a week and not longer than a month.
4. Acid environment protection
When exposed to or exposed to acidic materials, steam, or samples, they should be washed immediately, neutralized with a moderate sodium bicarbonate solution or other similar solutions, and then rinsed with clean water. Long-term exposure to acidic substances will damage the instrument. If long-term exposure to acidic substances is necessary, protective measures should be taken.
5. Clean the needle
After each use of the needle, the needle should be rinsed with organic solvents and cleaned with high-pressure disinfection to minimize needle contamination and the impact on later experiments.
6. Prohibition of long-term immersion
The bottom of the nitrogen blower is water resistant but not waterproof. After the test is completed, the nitrogen blower should be taken out and wiped clean in time, and the water bath must never be immersed in any liquid or placed in a place where immersion may occur. )
