The SFC5500 mass flow controllers are the perfect match for analytical instruments such as gas chromatography, mass spectrometry, or thermal analysis. Here, the users can benefit from a very high accuracy of 0.8% of measured value to build accurate scientific apparatuses. This is equally important for bioreactors, as well as for medical equipment such as ventilators, heart-lung, and anesthesia machines, and more generally speaking, in all gas mixing applications. In process control and industrial automation applications (for example coating and thermal processing), high repeatability and process control is what matters most. Here, SFC5500 delivers unmatched repeatability of 0.1% of measured value to minimize process variability. The same is true for numerous applications in chemical, plastics, and glass industries. Semiconductor applications such as plasma etching processes and thin-film deposition also require high speed. SFC5500 delivers flow control in under 100 ms to ensure very accurate process control.
