Labs do different types of testing - Gas chromatography (GC), High-performance liquid chromatography,(HPLC) and Thin Layer Chromatography (TLC) which is what our kit does -With GC or HPLC the same plant can be tested 3 times and get 3 different results, also if you took the same sample to three different labs you would get three different results. Basically there is no standard procedure from lab to lab for testing Medical Marijuana because of the lack of standard testing rules by the government.

3 Most common types of Lab testing

Thin Layer Chromatography (TLC) – sometimes called( HPTLC) **(Type of Kit we Offer) Thin layer chromatography (TLC) is a widely-used chromatography technique used to separate chemical compounds. It involves a stationary phase consisting of a thin layer of adsorbent material, usually silica gel, aluminum oxide, or cellulose immobilized onto a flat, inert carrier sheet. A liquid phase consisting of the solution to be separated dissolved in an appropriate solvent is drawn through the plate via capillary action, separating the experimental solution, whereas TLC can be configured for quantitative work

High Performance Liquid Chromatography (HPLC) High-performance liquid chromatography is a form of column chromatography used frequently in analytical chemistry. HPLC is used to separate components of a mixture by using a variety of chemical interactions between the compounds within the substance being analyzed and the chromatography column.

Gas Chromatography (GC)A Gas Chromatograph is a chemical analysis instrument used for separating volatile and semi-volatile compounds in a complex sample. The stationary phase in GC is contained in a narrow -bored column and the mobile phase is a gas. The volatile and semi-volatile components of a sample mixture are separated based on their varying partition behavior between the mobile phase and the stationary phase.The Reality is GC testing is not as good as we would like for testing of CBD, CBN,CBG, and some of the other substances in marijuana because the machines use heat to test these substances and they all evaporate at a lower temperature then THC. So you will get some results but they will not be that accurate and the coated tubes used in testing cost several hundred dollars apiece and are used for hundreds or thousands of tests before replacement, leading to problems from contamination and degradation of the column.HPLC testing is complex and does do cold testing but if you are looking for the highest THC% then you must test HOT & COLD which most machines are not prepared to do.As with GC, the columns must be re-used many times, leading to contamination and degraadtion problems, also calibrating the machines should be done after every batch is tested and that is not done, all these systems need expensive equipment and are costly.


TLC Lab Supply's CTK Test kits give THC results that have been compared to a properly run and managed GC machine on a monthly bases and even clients with no testing backgrounds have tested with the kits and have had no more then 1% difference from the GC machine. Working with experienced chemists the conclusion has been that if you are going to make any type of products for sale, you will need to do many test on your substances for batching and dosage for medical use,or you are just going to retail products from liquids to hand creams, all these substances will have to be tested in the USA before going to retail. It is not cost effective for any large or small company to spend a lot of money going to a lab for continues testing,Our kits used properly will give you consistent results if you use the correct amount stated for testing, so that you can create your substances or track your breeding for very little cost. Then once you have gotten your product to were you want it then you can go to a certified lab and have it tested so it can go to retail which will be the law that all substances will have to be tested by a certified lab at some point.Many labs are using our test kits already, some labs use our testing procedure and use no machines so instead of paying tons of money for initial testing using our kits is a sensible part of processing any type of cannabis product or substance, and some labs are telling clients to use the kits first and then come to them for final testing. It is a win win for everybody. Once you understand TLC testing you will see that it will become a standardized part of the cannabis industry. 


TLC Lab Supply's CTK Test kits is the practical and cost effective answer to growers and dispensaries and eliminates the extremely high cost larger labs charge for strain testing. Testing costs can go down to $3.00/strain using TLC Lab Supply kits which have been proven to be as accurate a measurement tool as a $175.00/strain test from a large testing lab using GC and HDLC instruments.  


Everyone knows more or less about the effects and laws around Marijuana and Cannabis. However, with changing times, it has become important to know the potency of these compounds to use them optimally. This is where TLC Lab Supply's CTK Test kits or Marijuana THC test kit comes into play.These THC test kits can be used to test the percentage of various cannabinoids in Marijuana plants and other Cannabis products. Thin Layer Chromatography is used to get the best test results. There are several cannabinoids (almost 70), but there are 8 which affect the most. The 8 most impactful cannabinoids are THC, THCv, THCa, CBD, CBDa, CBN, CBG, CBC. Out of these, THC or Tetrahydrocannabinol is the most widely known and abundant one. CBD or Cannabidiol looks like the most promising cannabinoid when medical conditions are considered. Overall, there is a lot of debate around the legalization and use of Marijuana. But, one can't overlook the necessity of testing them for various purposes.

Here are some reasons to test Marijuana and other Cannabis products. It will make way for better standards. With proper testing in process, there will be a better quality of the recreational drugs available in the market. It has a lot to do with the safety of the drug consumers. A completely comprehensive testing will make way for safe habits as well. When safety is a primary concern, testing has to be brought in. A well carried out test will make way for knowing the potency of the products. TLC Lab Supply's CTK Test kits   for determining THC percentage work on the principles of Thin Layer Chromatography and that will help you know the potency of every Marijuana product you buy.These are the 3 major benefits of testing Marijuana plants or Cannabis products available around. TLC Lab Supply's Marijuana THC test kits comply with the global standards of test kits and they work with plant material like oils, edibles, and tinctures as well. We ship our kits all over the world to spread the word on Marijuana safety everywhere.
