µPULSE Software Update 3.1

µPULSE 3.1 introduces a host of enhancements designed to streamline your work flow. Let's take a brief glimpse at the key advancements in µPULSE 3.1.


The Mixing Cycle feature helps to maintain sample uniformity and a consistent filtration performance over time. During mixing, the sample is recirculated across the filter medium, preventing localized high concentrations. Hence, we offer a mixing cycle feature, conveniently accessible through the following menus:


  • In AUTO PROFILE, use manual mixing or auto mixing cycle.
  • Manual Mixing: Tap the MIXING CYCLE button in the middle of the concentration.
  • Auto Mixing: Go to the General Setup of the Advanced Setup menu. Then, activate the Auto Mixing toggle button and fill in Auto Mixing Every and Mixing Cycle fields.
