Estimating Boiling Point and Vapor Pressure

To help scientists estimate boiling points and vapor pressures of the chemicals they work with, VACUUBRAND now offers helpful online calculators to derive these estimates. For more useful vacuum application-related calculators check out the Technical Resources section of oemvacuumpump.com.

5 Ways to Maximize Energy Savings in Lab Vacuum Generation

Local vacuum networks save considerable amounts of energy as compared to central vacuum systems.  The energy savings will vary from one project to the next, but savings of up to 70-90% are achievable. Even making very conservative assumptions about vacuum system usage, savings of 40% are common.  By reducing resource consumption, there are both economic and [...]

Vacuum…It’s everywhere: Space Engine Challenges Newton’s Laws

“For every action there is an equal and opposite reaction.” So says Newton’s Third Law of Thermodynamics. The principle is fundamental to space travel, as the combustion of propellant exhausted from the rear of the spacecraft imparts forward motion. But what if a rocket could be designed without reliance on Newton’s Third Law, and could travel [...]

Reliable Vacuum for Notre Dame’s New Research Labs

The University of Notre Dame is expanding rapidly.  Part of that expansion includes new lab buildings on campus.  In 2016, McCourtney Hall was built, adding 140,000 square feet of multidisciplinary research labs.  In part due to recent problems with central vacuum systems on campus – including the complete failure of one central system – the university [...]

Tools to help with vacuum equipment selection

We have developed a series of calculators and converters to help with some of the more frequently asked vacuum equipment questions that we run into. Vacuum & Flow Rate Calculator – convert between common units to measure vacuum pressure and flow rate. Vacuum Drying Process Time Calculator – have a drying application and trying to figure [...]

What’s behind your laboratory walls?

Traditional lab vacuum systems are often plumbed with standard copper piping. Initially this may provide the necessary system integrity (vacuum tightness), however, over time piping exposure to common harsh chemicals used in life science and chemistry laboratories can degrade these system components resulting in pitting and occlusions. This can result in performance losses and possible [...]
