Use maintenance 1. Heating medium: It is best to use distilled water and deionized water, which will prevent scale from forming on the water bath wall. Be careful not to use organic solvents as heating media.
2. Algaecide: When not heated, the algaecide is added to the water bath to prevent biofouling. Acidic algaecides should not be used and should ensure that the algaecide used does not affect the sample to be treated.
3, change the water: the water in the water bath is recommended to change one week, the longest is no more than one month.
4. Acidic environment: After contact or exposure to acidic materials, steam or samples, it should be washed immediately, neutralized with a moderate amount of sodium bicarbonate solution or other similar solution, and then rinsed with water. Prolonged exposure to acidic materials can damage the instrument. If it is necessary to contact the acid for a long time, protective measures should be taken.
5. Needle: It should be cleaned after each use of the needle to minimize the contamination of the needle. Organic solvent washing, autoclaving and Soxhlet extraction techniques can be used.
6, immersion: the bottom of the bath is water resistant but not waterproof. Never soak the water bath in any liquid or place it where it may be soaked.
