主要特点 Delta-8是专为高通量表面张力测量专门设计的产品,可应用于药物的研发、表面活性剂开发、adsorption isotherms的测量等领域。 Delta-8是一款全自动的表面张力仪,平行拥有8个天平来测量表面张力。Delta-8使用耐用的金属丝探针代替昂贵的威廉板和Du Nuoy环,测量前的探针自动清洗过程使得仪器的维护非常简单。Delta-8使用标准的96孔板,减少样品量的消耗,高通量的测试也极大的降低了人力。 仪器介绍 Delta-8 eliminates the drawbacks of conventional surface tension research by automation, miniaturization, and by ease of use and maintainance. Use of eight parallel microbalances, disposable microtiter plates, and automated du-Nouy probe cleaning unit allows researchers to focus on results instead of paying attention to instrumentation. The surface tension measurement used in the Delta-8 is based on the Du Nouy maximum pull force method, i.e. the maximum force exerted by the surface tension is recorded as the probe is withdrawn from the solution. Schematic illustration of measurement principle and the forces acting on the probe in a gas–liquid interface. Fp is the force acting on the probe, Fb is the lift due to buoyancy (weight of the displaced liquid), γgl is the surface tension, mm is the weight of the meniscus under the probe (the volume displaced by the probe is included in the meniscus), and q is the contact angle between the probe and the solution being measured. The latter is negligible in most cases.
