Sample Vial Cleaning Method

As an important instrument in the laboratory, the cleaning of sample vial is particularly critical. The specific methods are as follows:

Program I
1. In-bottle test solution of reverse-drying chromatographic sample.
2. Immerse in 95% alcohol, wash it twice with ultrasound and dry it, because alcohol is easy to enter 1.5mL bottle and can dissolve with most organic solvents.
3. Pour in clear water and wash twice with ultrasound.
4. Pour the lotion in the drying bottle and bake at 110 degrees Celsius for 1-2 hours. Be careful not to bake at high temperature.
5. Cooling and preserving.

Program II
1. Soak in methanol (chromatographic purity) for 20 minutes, then dry the methanol.
2. Fill the chromatographic sample vials with water, wash it with ultrasound for 20 minutes, and then dry it.
3. After that, the chromatographic sample vials were dried.

Program III
1. Rinse the tap water several times.
2. Put it in a beaker filled with pure water and ultrasonic for 15 minutes.
3. Change the water and ultrasound for 15 minutes.
4. Soak in a beaker filled with anhydrous ethanol.
5. Then take out the natural air drying.
