    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 […]

    Inchfab uses mass flow and pressure control in nanoscale fabrication systems

    Cowritten by Alicat; Mitchell Hsing, Ph.D., CEO & Co-Founder of Inchfab; and Parker Gould, Ph.D., CTO & Co-Founder of Inchfab Background: Nanoscale fabrication systems & Inchfab The increasing demand for computing power over the past 60+ years has led to exponential increases in both device complexity and production volumes. To keep up with this demand, […]

    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 […]

    Veloce echelle spectrograph utilizes closed-volume pressure control

    Dr. James Gilbert Dr. James Gilbert was the technical lead for the Australian National University’s development of the Veloce echelle spectrograph, which is now installed on the 3.9-meter Anglo-Australian Telescope at the Siding Spring Observatory in New South Wales, Australia. Veloce integrates a highly-customized Alicat closed-volume pressure controller for stable precision pressure control of air […]

    Creating a vacuum using a dual valve pressure controller and the Venturi effect

    One of our customers needed a way to control the pressure in a reaction chamber between -200 to +200 cmH2O. While the customer’s building had an ample supply of compressed air, they had no vacuum source. Without suction, they were unable to reach negative gauge pressures. They reached out to Alicat in search of a […]

    Fast, accurate leak testing using one flow controller

    Looking for a fast, accurate way to leak test your system? Whisper low pressure drop controllers provide a convenient, single instrument solution. A standard controller may also work, however stable leakages are best detected when the meter generates minimal pressure drop (line pressure due to frictional resistance). This makes the low pressure drop (as low […]
