Posted by Jennifer Collins on Jul 8, 2020 1:30:00 PM

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.

Pharmaceutical | Freeze-drying and Vacuum Ovens

Posted by Jennifer Collins on May 4, 2020 9:00:00 AM

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 shelf-stable powder. This powdered drug is later reconstituted at point of care for patient use.

Medical Vacuum Applications | Vacuum Sterilization

Posted by Jennifer Collins on Apr 9, 2020 12:37:00 PM

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 the many 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.

The most commonly used vacuum pumps run at one speed. Therefore, the pump is always driving toward the deepest vacuum 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.
