During remediation, unwanted contaminants such as residual solvent, water and terpenes are stripped from the oil and captured by the cold trap. The weight loss from removal of these contaminants will depend on the amount of contaminants in the starting material. About half the THC and some CBD also are captured by the cold trap.
The remediation process uses heat. If the starting material has not been decarbed beforehand, the remediation heat will decarb it. The loss of CO2 will represent about a 13% loss of weight for the cannabinoids being decarbed.
It is difficult to get all of the viscous sticky oil out of their buckets. Heating the buckets with heating blankets overnight makes the material less viscous and easier to transfer. Using squeegees and spatulas improves recovery but there always is some starting material left behind.
Transfer of the remediated oil out of the reactor and into the final containers is aided by heating the reactor and the draining from the drain valve at the bottom of the reactor. However, some transfer loss is still unavoidable.
