Fundamentals of Convection-Enhanced Pirani Gauges

Fundamentals of Convection-Enhanced Pirani Gauges Convection-enhanced Pirani gauges work on the same principle as thermocouple sensors, where vacuum measurement is made based on the rate of heat loss from an excited sensor wire. Additional heat loss occurs due to convection at higher pressures. This type of gauge takes advantage of this heat loss and the range of measurement is extended compared to a thermocouple-type sensor, whose usable range is considerably shorter. They also have a faster response time than thermocouples, in milliseconds compared to seconds. They are popular in a wide range of industries due to their wide range of measurement. DigiVac has

3 Reasons Why You Need a Bullseye for Your Vacuum Oven

3 Reasons Why You Need a Bullseye Gauge for Your Vacuum Oven The gauges that are often built into many of the vacuum ovens on the market are, in fact, not the best gauges for vacuum drying or extraction. These small, circular gauges are “inches of mercury” gauges. In this video and blog, we overview the 3 reasons why you should add a DigiVac Bullseye Gauge, to your vacuum oven set-up. The Bullseye Precision Gauge is a digital vacuum gauge has become the trusted standard for SPD processing, but lets explore why you should use it on your vacuum oven

Importance of Vacuum Control for Vacuum Ovens

Importance of Vacuum Control for Vacuum Ovens Benefits of Vacuum Controllers for Vacuum Drying Processes Benefits of Vacuum Control on Vacuum Ovens: Vacuum ovens, in general, offer a more gentle way to dry things. Adding vacuum control (or vacuum oven controllers) builds on these vacuum drying advantages. Vacuum control for a vacuum ovens is important because it: Provides precise control to the drying process, enabling a more repeatable drying process and result Slows down the initial pumpdown of a vacuum drying process, which helps to do two things: Ensure that lighter materials are not sucked into the vacuum pump Ensure

Why do I care about slew rate?

Why do I care about slew rate? In a critical process it may be necessary to slowly bring the vacuum level up or down at a specified rate so as to not disturb process material. This can be referred to as the slew rate, or ramp rate, of the vacuum level. A new feature for the Stratavac Touch is the ability to set a slew rate along with a setpoint for a valve and the controller handles the details.  In Vacuum, what we mean by slew rate is a specific or defined change in pressure over a defined timeframe. Some people

StrataVac | Behind the Name

StrataVac | Behind the Name How did STRATAVAC get its name? The prefix Strata is for Stratum. Webster’s Dictionary defines Strata as “a layer of material, naturally or artificially formed, often one of a number of parallel layers one upon another”. STRATAVAC, DigiVac’s Multi-Gauge Vacuum Controller, is customizable for a number of Vacuum Applications based on its ability to add additional driver cards to the vacuum instrument. And “Vac” for, well, vacuum ;). Strata (many layers) of Vac (vacuum) capabilities. Now, let’s dig into a few of the DigiVac STRATAVAC and STRATAVAC Touch lines features and benefits. Need to measure vacuum at one point of

Pharmaceutical | Freeze-drying and Vacuum Ovens

Pharmaceutical Freeze Drying and Vacuum Drying for Research and Manufacturing in the .01 Torr to 400 Torr Range Vacuum Pressure is used in Pharmaceutical Manufacturing to:  Help create bulk and active ingredients for FDA approved drug products Increase the shelf-life of a drug product Sterilize medical devices  Lyophilization, also known as freeze drying, is a process used for preserving biological material by removing the water from the sample, which involves first freezing the sample and then drying it, under a vacuum, at very low temperatures. The low pressure environment helps minimize oxidation during drying. Lyophilized samples may be stored much longer than untreated samples. The resulting precipitate is a

Medical Vacuum Applications | Vacuum Sterilization

Vacuum Instrumentation for Vacuum Drying and Sterilization of Medical Devices Sterilization of medical equipment is vitally important to render a product free from viable microorganisms (such as bacteria, fungi, and viruses). Steam is used in vacuum sterilization processes. The steam is put under pressure that is higher than atmospheric pressure (> 1 bar). A sterilizer configured to run a vacuum cycle will be equipped with a vacuum system. A typical vacuum cycle will begin with a series of alternating steam and pressure injections. The use of a vacuum controller to lower the vacuum pressure this will remove air from the chamber.
