Usage
Storage jars are used to hold cannabinoids, terpenes and prepared formulations between processing steps or during storage. Glass jars are commonly used because they are easy to inspect, clean and reuse.
The jar size is usually matched as closely as practical to the amount of material being stored. A container with excessive empty space leaves more oxygen in the headspace, which increases exposure to air. This is especially relevant for terpene-containing formulations and oxidation-sensitive cannabinoids.
For better protection, the headspace can be displaced with an inert preservation gas such as argon before the jar is closed. A reliable lid or seal remain important to limit fresh air from entering again and to reduce loss of volatile terpenes.
Borosilicate glass is especially useful when the stored material is regularly warmed before transfer because it tolerates repeated temperature changes better than standard glass.
Advantages
+Low-cost and reusable solution for storing formulations
+Sealed jars protect material from contamination and reduce exposure to outside air
+Transparent glass makes the material, remaining quantity and possible crystallization easy to inspect
+Available in many sizes, making it possible to reduce unnecessary headspace
Disadvantages
-Glass containers can break if dropped or exposed to excessive shock
-Material can remain around the threads and lid during transfer
