Measurement of surface tension of water under vacuum environment (about 9pa). We use Young-Laplace equation fitting method (ADSA) and correct the △P. To form a drop, we use such method as vacuuming the chamber with syringe is closed by a value at first, then stopping vacuuming and open the value of syringe to form a pendant drop of water due to pressure difference.
