    Raising the Equilibar: Pairing an Alicat with a dome-loaded pressure regulator

    In applications with extreme temperatures and pressures, severe chemistry, mixed phase fluids, and ASME BPE sanitary requirements, Alicat flow and pressure instruments benefit from pairing with Equilibar® regulators and valves. Equilibar back pressure regulators (BPRs) and flow control valves (FCVs) offer stable control across an extremely wide range of flow rates, with models offering control of Cv […]

    Optimizing atomic layer deposition using flow and pressure control

    Atomic layer deposition (ALD) is a subset of chemical vapor deposition (CVD) which uses cyclical deposition cycles. Unlike other types of CVD in which reactions are continuous, ALD reactions take place in separate steps so that deposition layers can be controlled more precisely, even to single-atomic layer thicknesses. Whereas other CVD techniques determine layer thickness […]

    Building CVD diamond machines with flow and pressure regulation

    In 2020, the lab-grown diamond market reached 19.3 billion dollars and by 2030 it is projected to reach about 49.9 billion. Lab-grown diamonds are safer, more environmentally friendly, and cheaper to produce than are mined diamonds. The main methods for lab-grown diamond manufacturing are HPHT and CVD. Although HPHT developed prior to CVD, it is […]

    Regulating cold plasma flow and pressure

    Plasma, the 4th state of matter, makes up a remarkable 99% of all mass in the universe, including stars and lightning. Cold plasma, sometimes called non-thermal plasma or non-equilibrium plasma, is a special type of plasma. While other molecular and atomic constituents remain near room temperature, cold plasma is made at ambient conditions when electron […]

    Inflating single-use bioreactor bags using dual-valve pressure controllers

    Single-use bioreactors (SUBs) offer key advantages over reusable bioreactors, including increased sterility and subsequently simpler and faster changeover between batches or campaigns. After the product is removed from the bioreactor, the user can remove the SUB bag from its holding container and dispose of it (generally via incineration). The new vessel can then be installed […]

    Hydrogen fuel cell regulation and testing solutions

    Hydrogen fuel cells are a clean, environmentally friendly alternative to traditional combustion processes. While they show tremendous promise, fuel cell regulation is critical to achieve the process efficiency required for them to become truly viable as an alternative energy source. Precise and adaptive regulation of system pressures and the mass flow of gas lines can […]

    Maintaining cryogenic temperatures with pressure control

    Cryogens are substances that liquefy at or below 120 K under standard pressure (760 Torr). They are commonly used in applications to keep liquefied substances at extremely cold temperatures, including cryopreservation, rocket propulsion, and medical imaging. Two of the most well-know cryogens are liquid nitrogen and helium. Liquid nitrogen is commonly used for cold storage […]

    Overcoming the challenges of high-speed aerodynamic tests using pressure control

    Aerospace development and testing applications often require high flow rates to pressurize large volumes. One example is in gas reservoirs, where the reservoir must be pressurized prior to conducting high-speed aerodynamic tests. Application requirements A customer approached Alicat looking to pressurize a 200 L gas reservoir to 1000 PSIG. The gas held in the reservoir […]
