Approaches to Vacuum Control

Establishing good control over vacuum processes has numerous benefits, such as helping to improve process yields, achieve more repeatable results, and reduce process times.  And there are several options for controlling vacuum processes to achieve these various benefits.  This post will briefly review some of the more common approaches to vacuum control.  Subsequent posts will…

Control cross-contamination through lab vacuum lines

It’s worth remembering that the vacuum lines in the central vacuum system serving your lab are sucking gases and vapors and maybe bio-aerosols into a common conduit. Once there, they mix with the emissions from other vacuum applications. As long as they stay in the vacuum lines, they will cause you little problem (except for…

Which type of vacuum pump is best for my lab applications?

When choosing a vacuum pump for their laboratory, many people find vacuum technology a bit confusing. Rather than wrestle with the details of vacuum pump specifications and how they relate to the application at hand, the temptation may be to choose the pump they had before (even though it may reflect aging technology), look for…

The Challenges of Supplying Vacuum for a Cleanroom

In certain industries, successful research, product development or manufacturing depends on the maintenance of a contaminant-free environment. Work on pharmaceuticals, medical devices and electronics, for example, may be compromised by particulates or airborne microbes. To protect these critical processes, cleanrooms are used to control airflows to achieve extremely low particulate loads. Operating the equipment needed…

Effective vacuum control for your lab – Part 2

In our last blog entry, we reviewed the challenges presented by using uncontrolled vacuum in the lab, and took a look at manual options for vacuum control. In this note, we’ll examine options for electronic vacuum control. Electronic vacuum control requires both detection and a control technique. The detection is provided by an integral vacuum…
