界面张力分析仪Drop Volume AnalyzerFeatures of the instrument surface and interfacial tension of liquids dynamic interfacial tensions in a time range of less than one second up to several minutes complements the profile analysis tensiometry at short times, in particular for liquid/ liquid interfaces use with any PC or laptop, no time-consuming filling procedure as it refills automatically from a reservoir temperature controlled cell small size and easy to handle correction of the viscosity effects at short drop times.
技术参数
Range of surface and interfacial tension: 1 to 100 mN/m, Resolution: ± 0.2 mN/m Time range: - constant drop formation: 0.2 s to about 1000 s - time scan (standard): 0.2 s to about 1000 s Drop formation: single drops or averaged number of drops Syringe volume (automatic refill): 0.1, 0.25, 0.5, 2.5 ml Density difference:> 0.1 g/cm3 Measuring duration: 1 min to 1 hour Measuring option: - constant drop time: arbitrary number of points - standard mode: selected points in a user given time interval Temperature range: 10 … 80°C Size of device (L x W x H): 200 x200 x 210 mm Weight: 3.0 kg Interface: RS-232 Power supply: 24 VDC, 40 W Extra accessories: Capillaries
