Unstable vacuum levels compromise lab accuracy

 This white paper explains how to fix that.

Inconsistent vacuum control disrupts reproducibility, slows down workflows, and risks sample integrity. Labs relying on manual or outdated systems often face pressure fluctuations that skew results. This paper outlines how precision vacuum regulation—using Welch’s advanced systems—improves consistency across filtration, distillation, and drying processes.

Welch’s approach centers on digital control, modularity, and real-time feedback. The paper compares traditional setups with modern vacuum networks, showing how labs can reduce downtime and improve throughput by switching to programmable systems. It also includes case data from pharma and biotech labs that upgraded to Welch controllers and saw measurable gains in process reliability.

What You’ll Learn

  • How vacuum fluctuations affect lab outcomes
  • Which processes benefit most from precision control
  • What features matter in a vacuum system (and which don’t)
  • How Welch systems integrate with existing lab infrastructure
  • ROI data from labs that upgraded

FAQs

Because pressure stability directly affects flow rates and evaporation. Even minor fluctuations can cause incomplete separation or overdrying.
