Fractional Distillation and Solvent Recycling

If you need consistent, high quality recycled solvents, you need fractional distillation. The good solvent and the contaminants have different boiling points. By paying attention to the boiling point (vapor temperature) you can separate the good (clean solvent) from the bad (contaminants). Here is an example of the fractional distillation of xylene. Choose: A solvent […]

Reduce your waste generator status and save a ton of paperwork

Labs spend significant sums on buying and disposing of histology solvents. Unseen to most, are the regulatory costs of complying with local and federal hazardous waste regulations. The more hazardous waste your facility generates, the greater the regulations. Waste solvents from the lab are classified as hazardous waste by the US EPA. Depending on the […]

Tips For Successful Cannabis Terpene Distillation

  Refined cannabinoids such as THC or CBD are some of the most commonly sought after compounds when performing a vacuum distillation process on crude cannabis extract. However, non-degraded terpenes can also be collected from certain material using properly configured cannabis distillation equipment. In order to successfully distill terpenes from cannabis crude extract, the following […]

Cannabis Oil Products – A Time Line

How are THC/CBD products such as vape cartridges, dabs and edibles created?                 Grow It It all starts with “the grow”.  Most cannabis grows are done in a controlled room. Light, water, temperature and other environmental factors are carefully regulated to maximize cannabinoid production. Cannabis plant genetics are […]

Vacuum pump oil contamination can prevent a distillation system from reaching low vacuums (0.01 mmHg) ideal for THC and CBD distillations.  Sometimes terpenes can sneak past the cold trap and spoil the vacuum pump oil. A little bit of contamination can cause a lot of havoc in a vacuum pump. Here are a few tips […]

Fractional Distillation versus Simple Distillation

Simple distillation Simple distillation is a single stage distillation where a liquid mixture is boiled and the resulting vapor condensed. Wiped film and short path distillation are examples of single stage distillation. Simple distillation can provide a moderate improvement in purity. It is useful in situations where you are attempting to separate compounds with very […]
