The Basis line of mass-flow controllers has been expanded to include the new 20SLPM model (photo). Specifically designed for original equipment manufacture (OEM) and process integration, this small-footprint instrument provides fast, accurate control of gas flowrates in a wide range of applications, including sparging into liquids and sample dilution, as well as many gas-mixing applications. Suitable for use in OEM gas analyzers, automated gas mixing on process lines and anywhere basic mass-flow-only control is required, a 100-ms control response enables Basis controllers to react in realtime to upstream fluctuations. Basis controllers are available with the following multi-gas calibrations: air, argon, CO2, N2, O2 and N2O (selectable over serial connection). Furthermore, helium and hydrogen are also available in single-gas units. — Alicat Scientific, Tucson, Ariz.
