Wilhelmy Plate Tensiometer for Equilibrium and Interfacial Tension
平衡与界面张力用 Wilhelmy 板法张力仪
Surfactant chemists finding a CMC need true equilibrium readings, which a stationary plate provides. This Wilhelmy tensiometer resolves 0.001 mN/m with ±0.05 mN/m accuracy using a 10 × 20 × 0.2 mm plate on a 0.01 mg balance. Automatic dosing at ±0.5% builds concentration series in 10–80 mL samples, at 5–90 °C.
