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

2020 Innovations in Vacuum Measurement and Control

2020 Innovations in Vacuum Measurement and Control Read about DigiVac’s year end highlights in this blog and share some holiday cheer! Greetings from DigiVac! This has been a unique year for everyone, and an especially challenging one for many. In the holiday spirit, DigiVac would love to shed some light and positivity by sharing our most cheerful memories of the year. DigiVac spent the year cooking up some exciting innovations to help make Vacuum Measurement and Control easier. By eliminating typical bottlenecks, our solutions have helped make our customers lives a bit less difficult. Here are a few 2020 highlights: Supported

DigiVac Case Study: Automatic Pump Down Control

DigiVac Case Study: Automatic Vacuum Pump Down Control System Featuring the DigiVac StrataVac Touch vacuum controller and Agilent IDP-10 vacuum pump “A large research laboratory reached out to DigiVac to help them automate their Vacuum Stations. They wanted to move from their current process that included manually-actuated electronic valves to an automated vacuum control system.” READ THE FULL CASE STUDY: You can access and continue reading the full case study by clicking here. WATCH OUR VIDEOS: You can watch several videos describing the new configuration by clicking any of the hyperlinks below. Overview of Our Pump Down Solution StrataVac Touch

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.

Don’t Forget the Grease!

Don’t Forget the Grease How many connections do you see? When putting together distillation systems that function under vacuum, you cannot forget to use vacuum grease on all the connections or leaks will happen. Tracking down a leak after everything is set-up just leads to frustration and wastes time! Important Considerations for Set-Up All the glass parts should be handled gently, washed, and dry before loading. A good quality vacuum grease should be applied to each joint and connection before installation that includes all glass and vacuum fitting interfaces. Lastly, check the vacuum hoses and pump for proper function. What

Benefits of Throttle and Bleed Vacuum Control

Benefits of Throttle and Bleed Vacuum Control The most commonly used vacuum pumps run at one speed. Therefore, the pump is always driving toward the deepest vacuum control level possible where they function optimally. Just because this is the sweet spot for your vacuum pump, doesn’t mean it’s the best vacuum level for your process. Applications of vacuum technology take place over a wide range of vacuum from ultra-high vacuum all the way up to atmosphere. Most often for industrial vacuum processing, users are ideally looking for a vacuum level that differs from the ultimate pressure of a pump; therefore,

Recap of AVS 2018 – Long Beach, CA

Recap of AVS 2018 – Long Beach, CA Two weeks ago (10/23), the DigiVac team walked into AVS 65 at the Long Beach Convention Center with excitement, eager to show exhibit attendees our new product developments. On display, we had a few products, some new, and some known but updated in appearance and functionality. Our booth visitors found the traditional thermocouple Bullseye with a Bluetooth connected to our Vacuum Gauge 2.0, StrataVac 2018 with one thermocouple sensor and our brand new StrataVac Touch connected to our recently launched VacStable valve, a thermocouple sensor and an MKS 523 gauge. Everything was
