Vacuum Tensiometer is a unique custom-made instrument to measure surface tension of molten viscous polymers. It employs micro-Wilhelmy method to reduce equilibration time for viscous liquids. Melting of polymers and measurements are performed in oil-free vacuum with residual gas pressure below 10-5 Torr.
