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

RoHS Compliance and DigiVac Gauges

RoHS Compliance and DigiVac Gauges What is RoHS? Restriction of hazardous substances, abbreviated as RoHS, is a protocol many companies worldwide put into place in 2006. Why? Because when the European Union decided in 2003 to standardize the practice of minimizing or removing all materials that could be harmful, electrical and electronics companies had to comply in order to maintain business with Europe. Additionally, following the shift in production processes meant that end products became safer for customers. Why was there a sudden shift to initiate the protocol? The ultimate move toward removing certain materials was prompted by the need
