Survismeter, 3-in-1 instrument for simultaneous measurements of Surface Tension, Inter Facial Tension (IFT) and Viscosity
Abstract
The article presents Inter Facial Tension (IFT) (ift, N m-1) of benzene-water; surface tensions (, N m-1) and viscosities (, N s m-2) of ethanol, glycerol, ethyl acetate, n-hexane, diethyl ether, chloroform, benzene, carbon tetrachloride [CCl4], formic acid, measured with Survismeter with – 1.1x10-5 N m-1, – 1.3x10-5 N m-1 and – 1.1x10-6 N s m-2 accuracies respectively. Also the surface tension and viscosities of carboxymethylcellulose (CMC), dodecylbenzenesulfonicacid (DBSA) and tetramethylammoniumhydroxide (TMAH) in aqueous media have been measured with survismeter at 298.15 K. IFT of water and benzene interface was determined with survismeter. The survismeter saves resources, users efforts and infrastructure more than 80 % as compared to usual methods and prevents 80% disposal of materials to environment. It very accurately measures surface tension and IFT of volatile and poisonous liquids at any desired temperatures as liquids are jacked (jacketed) in closed glass made bulbs.
