Operating Cost Benefits of Oil-Free Vacuum – Part 2
In part 1 of this white paper, we reviewed the general advantages of using dry, chemical-resistant diaphragm pumps for process scale-up applications. In part 2, we will delve into the process of configuring the mini-plant in order to realize the…
Dry, Chemical Resistant Vacuum for Process Development and Kilo Labs
VACUUBRAND's dry, chemical resistant pumps provide an ideal solution for use in process development, scale-up work, and kilo labs. With no sealing fluid to replace, our dry pumps provide a low maintenance, low operating cost alternative to oil-sealed rotary vane…
Vacuum Measurement – Pirani Gauges
Pirani gauges are a group of indirect measuring pressure gauges which measure the thermal conductivity of the gas sample. Pirani gauges are typically used in the fine vacuum range (1 torr - 10-3 torr), as this is the range where…
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…
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…
Vacuum Pump Sizing – Estimating Flow Rate
In our last post, we talked about our pump selection guide as one tool that we've made available to identify the right vacuum pump for your needs. This is a great tool to use to quickly narrow down your options, especially…
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…
Vacuum Unit Conversion
One of the most common issues we help customers with is how to measure units and communicate that information to others. While this might sound simple, there are a multitude of units used to measure pressure. The potential for confusion…
Beyond Gravity: Centrifugal Separations in CPI Operations
Follow these recommendations to select the right centrifuge for your application Many chemical process operations require the separation of multiple phases. This can be done in a number of ways, including simple gravity separation, traditional or crossflow membrane filtration and…
