There’s a better way to remediate THC from hemp extract or distillate. CBD Isolate is very popular due to its purity, but the minor cannabinoids are left in the mother liquor. Low THC or THC free hemp extracts are popular because they have the full spectrum of cannabinoids with little or no THC. The products […]
When buying cannabinoid products in bulk, you will often find yourself thinking about the color. Color can be an important indicator of quality in some cases. No one has any desire to consume a concentrated black tar. Color is not the only indicator of purity though. Test results from a certified lab should do […]
Solvent recovery is an essential part of any hemp or cannabis lab. Whether you extract with a liquid solvent or winterize, you will need a method of bulk recovery. Not to be confused with solvent recycling, solvent recovery is the process of removing the vast majority or all of the solvent in your crude […]
If you have 5 minutes a day, you have enough time to recycle your solvents. That may sound like an exaggeration but recycling doesn’t take much time. A good recycler does most of the work for you. You just need to give it solvent to recycle, push the start button and….that’s it. The recycler does […]
The recycled purity can depend a lot on the recycler being used. With a well-designed recycler you can expect high purity recycled solvents. The table below shows typical purity and concentrations. A manufacturer should be willing to guarantee the recycled product purity and concentration in writing. Not only should the purity be high but the […]
Q: Our lab is already crowded. Does a recycler take up much space? Space is always in short supply. Choose a “space efficient” recycler and you are on your way to saving. Every recycler has a set of written installation requirements. That gives details about what a suitable space is. These requirements are there to […]
Q: I’ve heard that a lot of histology labs are recycling their xylene, alcohol and formalin. What are some reasons to recycle solvents? Don’t throw it away! Just clean it! The same is true for used solvents…they are just dirty. Don’t throw them away. Recycling removes the dirt (contaminants) and makes them just like new. […]
Q: My old recycler needed water and a drain. Do today’s recyclers need a water hook up? No, you don’t need a water hook up or drain. Older solvent recyclers worked great but used condensers cooled by water. Today’s solvent recyclers use condensers cooled by air. So no water or drain is required. Q: Does […]
A well-designed recycler can recycle a solvent forever! Solvent used for tissue processing or staining becomes contaminated with stain, water, fat, protein, wax, and biological materials during use. The recycling process removes these contaminants from the good solvent. Reuse of the solvent is unlimited since it is brought back to the original purity each time […]
Q: Do filter based recyclers work? Yes and no….mostly no. There are commercial filter recyclers available for alcohol and formalin. There are no filter recyclers for xylene on the market. Alcohol – What does a filter recycler do? With use, the alcohol concentration gradually gets weaker due to water absorbed from the tissue and carry […]
