Micromeritics

The FT4 was designed with one purpose in mind — to characterize the rheology, or flow properties, of powders. This remains a primary function today, but the instrument, accessories and methodologies have been continuously developed to the point where the FT4 is now considered a universal powder flow tester. FT4 Powder Rheometer intended for use in a laboratory environment for measuring the rheological properties of powders, pastes and semi-solids. The FT4 employs unique technology for measuring the resistance of the powder to flow, whilst the powder is in motion. This causes many thousands of particles to interact, or flow relative to one another, and the resistance experienced by the blade represents the difficulty of this relative particle movement, or the bulk flow properties. Excellent reproducibility is achieved by moving the blade in a precise and reliable way.

Micromeritics and Powder Rheology - PowerPoint PPT Presentation

The term micromeritics was given to the science and technology of small particles by J. DallaValle [ citation needed ]. It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. The knowledge and control of the size of particles is of importance in pharmacy and materials science. The size, and hence the surface area of a particle , can be related to the physical, chemical and pharmacologic properties of drugs. Clinically, the particle size of a drug can affect its release from dosage forms that are administered orally, parenterally , rectally and topically. The successful formulation of suspensions , emulsions and tablets ; both physical stability and pharmacologic response also depends on the particle size achieved in the product.

Сьюзан казалось, что она сходит с ума. Она уже готова была выскочить из комнаты, когда Стратмор наконец повернул рубильник и вырубил электропитание. В одно мгновение в шифровалке установилась полная тишина. Сирены захлебнулись, мониторы Третьего узла погасли.

Developed as a direct and modernized successor to the widely used Fisher Model 95 Subsieve Sizer FSSS , the Micromeritics SAS II utilizes a built-in computer and touchscreen to perform measurements easily and quickly in a laboratory setting or on a production floor.
