CSC DuNouy Tensiometer
Available in two models: CSC Precision DuNouy Tensiometer (upward direction). This model tensiometer provides precise readings of upward interfacial and surface tensions by the ring method to values reproducible within ± dyne/cm. This is specified for determining interfacial tension of oils against water by the ring method ASTM Method D971 and solutions of surface-active agents in ASTM Method C1331. It is also specified for testing synthetic rubber lattices in ASTM Method D1417 and determining... (read more)
