Introduction to Crystallization Technique
To create a starting material for crystallization, use advanced short path distillation techniques.
To ensure that your compounds are not oxidized, do not let them linger longer than necessary. During distillation of a rich plant extract that is high in curative, it may be necessary to re-wash repeatedly through short-path distillation apparatus to obtain a clean result. After each process, a decrease in the boiling point should be noticed. Optimally, a healthy batch should remain above 80%. Following distillation, dissolve the curative in pentane at a 1:4 ratio and cycle the solution to promote crystal growth.
Maintain clean solvents, environment, hardware, and a sterile surface to achieve an ideal result. Begin by heating the solution to 115°F,
then cooling it to 40°F. Repeat this process three or four times – setting the cooling point to a constant 40°F, and layering the internal solution by weight. If a lot of fluid is lost, add pentane back during the heating phase.
As the temperature is lowering, drop a blanket seed--a few small, hard crystals--into the mix around 60°F. Once this step is complete, move the solution to a cool, dry, dark spot, like a spare oven at a temperature not exceeding 50°F. Vacuum enough of the pentane to make a cloudy appearance and wait for the crystals to start growing.
When the growth begins to slow, remove the pentane with a sweeping nitrogen gas. Take the crystals, freeze them in a stainless container, and clean them by washing off the THC 'mother milk' using a chilled pentane chemical spray. Reheat the crystals a few degrees above their crystallization temperature and vacuum with a nitrogen sweep gas to dry them out.
The cure that you have here is at a high concentration. When you heat and cool the solution repeatedly, it causes the molecules to bind together and form solids, which is what seeding is for. The cure can grow on its own and achieve a purity rate of 98-99%. The yellow materials on the surface are the impurities that appear when the cure is forced to the top as it starts to bond. These impurities can be cleaned off and the leftover fraction can be kept and re-used to prevent waste.
It is time to stop paying for the basic crystallization process. By getting a crystal like this, you are almost 97-98% of the way there to achieving a high-grade cure rate. It is the subsequent steps that require more precision and equipment to reach the ultra-pure ideal. To maintain safety, it is recommended to include a reliable high-quality vacuum pump, preferably with a controlling device.
