WebIn the typical process it takes to sublimate, you have ice, water, then gas. But with the additional process of freeze drying, it takes the process into consideration of preservation to keep the botanical fresh and well preserved for consumer use. The proper preservation of cannabis products is what makes the addition of vacuum valves so important. WebMost vacuum gauges are graduated in inches of mercury (in.-Hg) and millimeters of mercury (mm-Hg). Some also show the modern metric scale of kilopascals (kPa). For comparison, 1 in.-Hg equals 25.4mm-Hg, or about 3.4 kPa. For this review, we'll stick to in.-Hg, or simply inches of vacuum.
