Design of Experiments (DoE):How to Handle Hard-to-Change Factors Using a Split Plot
This methodology facilitates multifactor testing. However, it comes at a price: a loss in power for detecting effects The traditional approach to experimentation — often referred to as the “scientific method” — requires changing only one factor at a time…
Vacuum Measurement – Capacitive Gauges
In one of our prior posts, we talked about the key differences between direct and indirect vacuum gauges. One of the most common direct gauge technologies is the capacitive gauge. This post will review how these gauges are constructed and…
Significance of Flash Fire Points
FLASH AND FIRE POINTS IN HEAT TRANSFER FLUIDS Download as a PDF file FLASH POINT DEFINED A “flashpoint” is the temperature at which a fluid generates enough vapor to be ignited (“flash”). There are two common test methods: Open Cup (ASTM D92) and Closed…
Vacuum Measurement Made Easy
Finding a vacuum gauge for monitoring chemical processes can be a challenge. There are few gauges that simultaneously cover the appropriate vacuum range with sufficient accuracy and have the ability to cope with regular exposure to aggressive chemicals. VACUUBRAND's VACUU·VIEW™…
Vacuum Measurement – Direct & Indirect Gauges
Because vacuum technology spans 15 orders of magnitude (103 mbar - 10-12 mbar, or 760 torr - 10-12 torr), there is no single vacuum gauge that can cover the full range. Consequently, a number of different gauge technologies have…
Microreactors: Lessons Learned From Industrial Applications
Implementing microreactors in chemical production is quite a challenge. How these challenges can be met is described here At the heart of a chemical process is the reactor, where the conversion of reactants to products occurs. Depending on the need…
Vacuum Pump Sizing – Selection Guide
Another question that we often hear from our customers is, what pump do I need? The right answer depends upon a variety of factors - such as the nature of the process or application, the working pressure and/or flow rate…
Onsite Nitrogen Generation Via PSA Technology
Ongoing advances in both adsorbent materials and system engineering allow today’s pressure swing adsorption (PSA) systems to produce nitrogen of varying purities and volumes at relatively low cost compared to cryogenic air separation Nitrogen production that is carried out using…
Diaphragm Vacuum Pumps in Process Operations
Vacuum is a very widely used utility in the process industries – from pharmaceutical and chemical to food and biotechnology. While some applications require fairly deep vacuum – so-called “fine” vacuum – many other operations rely on vacuum in the…
The Chemical Resistant of VACUUBRAND’s Pumps
For many people, one of the most important features to consider when sourcing a vacuum pump is the ability of that pump to hold up over the long term. Pumps are exposed to a wide range of operating conditions that…
