Scientifically speaking, a vacuum is a space of such extremely low pressure that there is no matter present to affect the processes that occur there. Outside of the cold vacuum of space, a vacuum can be created right here on earth. Using a vacuum pump, air and other particles can be removed from a rigid space to create a man made vacuum chamber.
How Do Freeze Dryers Work?
When most people think about freeze drying, Neapolitan astronaut ice cream bars are usually one of the first things that come to mind. And yes, it’s true that freeze dried foods are a NASA staple. But freeze drying is so much more than that. Let’s take a closer look at the scientific process and applications of modern freeze drying.
Freeze-Drying for Cannabis Preservation
Freeze drying, invented in Paris in 1906, is a very gentle dehydration process used to preserve high quality foods. During WWII, the process was implemented to preserve blood serum. Since then, freeze drying has become a critical process for preserving foods, pharmaceuticals, and a wide range of other products–even cannabis.

How Vaccines Work and Why Temperature Matters
We think vaccines are pretty cool. Unlike most medicines, which treat or cure diseases, vaccines actually prevent them. Thanks to vaccines, many life-threatening diseases have now been nearly eradicated. However, with great power comes great responsibility; effective vaccines require careful temperature control from creation to administration to remain effective. How Do Vaccines Work? Vaccines contain […]
