50g/l NaOH aqueous solution---distilled water---acetone and chloroform---dry with a vacuum pump
Ensure the needle core not to be stained and blocked from high boiling point material in the liquid. Do not use strong alkaline solution to wash it to prevent the glass tube and needle from be corroded and water or gas leakage.
2. Ensure correct operation and use carefully to ensure the needle and pushrod not to be curved. Clean after usage and put into the packing box.
3. The glass syringe is not suitable for absorb solution with rough floating substance and used under high temperature. 10-100ml syringe needles can be made it through with 0.1mm stainless steel wire when blacked, it should not be burned by fire because it will make needle loss the puncture ability.
