buy sf6 mix microhydrometer
Microfluidic mixing using flow focusing. One of the important parameters for mixing efficiency is the mixing path. The shorter it is, the more compact the microfluidic mixer is. Consequently, it will be easier to integrate in the general scheme of a microfluidic chip. One of the methods to reduce the mixing pass is mixing through flow focusing.

high voltage Sulfur Hexafluoride breaker Prospect
The climax of my career was the application of the gas SF6 (sulfur hexafluoride) to high voltage switchgear, including the first 500 kw circuit breakers put into service in the United States. It all started with our attempts to answer customers' urgings to find a nonflammable substitute for oil in the design of high power circuit breakers.
