Multiflo engineers offers fluid surface tensiometer pc500-lv, manufactured by sensadyne, usa. The productuses a patented maximum bubble pressure, viscosity compensated method for measuring both dynamic and static surface tension. All measurements are calibrated against known standards. The method is completely independent of probe depth and ambient pressure, and unaffected by foaming or surface contamination. Instrument includes new features such as automatic calibration - temperature corrected, water and ethyl alcohol standard tables; viscosity compensated - designed to correct for high viscosity and high solids fluids; automatic surface age measurement - in real time no supplemental calculations required; pressure testing from ambient to 225 psi, with supplemental pressurized vessels and reactors; automated mass flow controllers - no manual flow adjustments; computer controlled flow rates for precise measurement and repeatability; expanded dynamic flow range from milliseconds to minutes; the widest range on the market; and precise differential flow settings - all probes have individual mass flow controllers. Applications: in r&d for dynamic and equilibrium surface tension measurements, critical micelle concentration [cmc] determinations [dynamic and equilibrium], formulation studies and comparison testing,3-dimensional formulation characterisation, fluid r&d, in process and pressure applications for continuous in- process and pilot plant reactor measurements, pressurized surface tension measurements of liquefied gases, measurements of liquid aerosols and pharmaceuticals under pressure, etc.
