Residual Solvent vs Vacuum Purge & Whipping

image (1)

As cannabis concentrates become more common, we often get questions about vaccuum purge time and whipping, in relation to hydrocarbon extractions. A client recently submitted four concentrate samples for Residual Solvent Analysis (RSA). The first three samples were identical except for the vacuum purge time (72, 92, and 120 hours). The forth was also identical […]

What is Residual Solvent Analysis?


In the manufacturing of cannabis concentrates and extracts, solvents (water, butane, carbon dioxide, ethanol, etc.) are used to extract the active ingredients from plant material to produce a resinous, sometimes glassy product. Steep Hill Halent regularly tests solvent extractions for residual solvents, helping manufacturers ensure the quality of their product, and empowering consumers with greater […]

Cannabis Concentrate Testing: Can Dabs be Safe?

A big thank you to Om Healing and Wellness Collective for putting together this interview with Addison Demoura, Steep Hill Halent Founder and COO.  

Everything You Didn’t Know About Vaporizing Cannabis


CB Can-D Sap/Taffy Q: Who invented Vaporizing? A: Ask the Ancients. We’ll expound on that in a moment, but first, an explanation: Vaporizing can be defined as a ‘medicinal delivery system for the respiratory system, both upper and lower’. In the upper respiratory tract, including the sinuses, the vapors/fumes are intended to effect nerve ending […]

Harlequin, And Why It’s Unique


Harlequin Cannabinoid profile. Admittedly, the cannabis community is currently very focused on high CBD to THC ratio strains, like Cannatonic-c6 and ACDC, but they are not unique in the two ways Harlequin is. Harlequin has a CBD:THC ratio that is almost always 5:2. That is because the primary phenotype (dominate 50% of the time) is […]

Mother Plants Grow Old


  Mother Plants Grow Old It’s an old story: the grower can’t understand why the last three batches of clones from his mother plant ‘Old Reliable’ keep getting lower and lower potency values “….no matter how I change up the lighting, micro-nutrients, etc… originally my plants tested 15% CBD-A and 6% THC-A, now they down […]

Phytocannabinoids, An Overview


Cannabisol, known as the “Butterfly of Cannabinoids,” is made from two THC Molecules and is one of the rarer phytocannabinoid molecules. Terpenoids comprise a very large family of related chemical compounds. Within this group, there are many sub-families, including Terpenes (where the family gets its name), semiterpene lactones, cannabinoids and others. Among the Cannabinoid family […]

Glycerin Tinctures


Glycerol model: C3H8O3 “Why are my Glycerin tinctures so dilute all the time?” In the now countless samples we have analyzed, clients are initially surprised and disappointed in how dilute their glycerin-based tinctures are. The first question they frequently ask is if there is something wrong with our analytic instrumentation. It’s not the instrumentation. For […]

Medicinal Cannabis and Your Pets


  Unless raw cannabis is old, there is little to no THC in it, and this means you can treat others with it without getting them high. The plant naturally produces cannabinoid acids, like THC-A, which are strongly anti-inflammatory, but NOT psychoactive. Upon aging (with heat) the THC-A converts to the psychoactive THC form. If […]

Herbal Extractions, Alkaloids, and Terpenoids

“Like dissolves like” is an old rule of thumb that works well and applies to herbal extractions. There are two major groupings of medicinal plants: plants that mostly produce Terpenoids, and plants that predominantly produce alkaloids. In centuries past, terpenoidal plants were extracted with wine (because of the alcohol) and alkaloidal plants were extracted with […] search-me PHP Developer, Web Developer ,Web Consultant, WordPress Developer , Freelancer, Gaurav Pathania, Gaurav
