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

    Inflating single-use bioreactor bags using dual-valve pressure controllers Background: installing & inflating single-use vessels Single-use bioreactors (SUBs) offer key advantages including increased sterility and subsequently simpler and faster changeover between batches or campaigns. After the product is removed from the bioreactor, the single-use bioreactor bag can simply be removed from its holding container and disposed […]

  • 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. We first […]

  • Regulating vacuum in test system when the vacuum source varies

    Regulating vacuum when the vacuum source varies The efficiency of any vacuum process depends greatly on the stability of the vacuum that is maintained in the chamber. Examples of this abound, including ensuring a clean diamond with the desired internal structure in artificial diamond manufacturing and or carbon nano tube generation, where a stable vacuum […]
