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

    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 […]

  • Inverse pressure control tutorial: Switching from forward to back pressure control

    Inverse pressure control tutorial: Switching from forward to back pressure control A forward pressure controller can be reconfigured into a back pressure controller by following two simple steps. First, you must swap the valve location (tutorials linked below). You can then activate inverse pressure control using either the front display or serial communications. In this […]

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

    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 […]

  • Veloce echelle spectrograph utilizes closed-volume pressure control

    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 […]

  • Increasing vacuum deposition speed and stability with upstream pressure control

    Placing pressure control devices upstream of the chamber in vacuum coating applications saves time, cost, and increases accuracy in vacuum deposition tools.

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

    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 […]

    Fast, accurate leak testing using one flow controller

    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). […]
