  • Appnote: Improving color dosing for liquid detergents

    Improving color dosing for liquid detergents Why is some laundry detergent blue? Many household liquid laundry detergents are easily recognized by their distinct blue color (sometimes also green or purple). Besides playing an important role in brand recognition and customer appeal, these colored dyes also serve a more functional purpose. White fabrics often lose their […]

  • Case study: Natural gas monitoring with framergy

    framergy: Making the world cleaner with metal organic frameworks Metal organic frameworks (MOFs) are a novel class of nanomaterials which are highly effective as a solid adsorbent and utilize their unique “cage-like” structure to trap molecules. Because of these properties, MOFs have been studied for numerous fluid storage, separation, and purification applications. The company, framergy, […]

  • Appnote: Fast, flexible leak testing for single-use bioprocessing

    How do you know that your bioprocessing is free from costly leaks or integrity failures? Leak testing of single use systems can now be accomplished easily and quickly with an Alicat Scientific Whisper Series Mass Flow Meter.

  • Appnote: Testing a tube bore for imperfections

    When Alicat received an inquiry to test bore imperfections in 0.001 bore tubes, our engineers stepped up to the challenge.

    Appnote: Filter characterization with differential pressure

    Filter characterization with differential pressure An Alicat Differential Pressure Controller is used to characterize a filter’s flow vs. a pressure drop curve. The PC-15PSID-D pressure controller is used to set the pressure drop across the filter. The M-10SLPM-D mass flow meter is used to measure the flow rate required to generate that pressure drop. As […]
