Thin Layer Chromatography, CTK Test Kits -3 kits available

Thin Layer Chromatography testing has been used in labs for years. It is taught in many University chemistry courses. This test is in full compliance with the guidelines of the World Health Organization concerning the safety and quality of medicinal plant materials.(WHO/PHARM/92.559). cGMP-compliant and U.S. Pharmacopeial Convention Certified (USP) / FDA approved. This kit test for THC, CBD, CBN, CBG, THCV and more in your cannabis products or plant material. Our kits always have the freshest supplies, and are unique to any other kit on the international market today. In some cases, laboratories are now using our kits with their GC and HPLC machines when testing edibles and oils, with an easy to use fully custom written manual, sample charts giving you up to 100% sample comparison values for oils, edibles and more. We are always available for questions and have sold thousands of tests. We include both a 1-3 ml plastic pipette and a 1-3 ml syringe to put your fluids into the reaction tubes and to put your fluids into the developing jar whichever is easiest for your use.

Update: Client feedback has shown that some products like honey, cream based or any heavy base mixed substances take time to go up the micro capillary tubes and at times have created a small clog in the micro capillary tubes which come with the kits, were as the Variable Pipette takes no time to transfer thick samples from the reaction tube to the tlc plate and has not clogged the pipette tips. So we strongly suggest purchasing a Variable Pipette (it comes with 100 tips) for testing any thick based products, it will replace the micro capillary tubes in your kit. Almost all our business clients end up purchasing this item, they save time and are very accurate. (It is currently included in kits # 2 & # 3 and the mini lab kit

Variable Pipettes .5-10 ul

When using the cannabis test kit #1 ( test kits 2 & 3 have the variable pipette included in the kits) you will be using the included micro capillary tubes and bulb to transfer the sample from the extraction tube (plastic test tube) to the TLC plate.

Using the 2ul micro capillary tubes takes a little time, for the sample to go up the tube and to put it on the plate which is not a problem an is used a lot for personal testing, some client feed back suggests some heavy creams and oils may clog the glass tubes and if you are planning on doing a lot of testing then for fast and accurate transferring of fluids from test tubes to tlc plates most labs use a "variable pipette" which by setting the amount of fluid to be extracted (using the top of the knob), can easily pull the exact amount of fluid needed (in our case 2ul or 4ul) from the extraction tube and quickly drop the sample on to the plate with the push of the button, also has tip ejector for quick change applications and an ergonomic handle for long term use. Directions for use are included in box.

4 Piece Mini Lab Package


This is a perfect start up mini lab; many areas in the USA, Canada and other countries do not have labs available for testing products in their local areas. Our kits have been used in many labs in conjunction with GC and HPLC machines but many clients have also started small labs without other testing equipment, and have been performing with consistent accurate.

When you add a microscope for mold, a variable pipette for fast accurate sample transfer and a balanced scale for precise sample weight you are in business for less than the cost of 6 cannabis test done in a average machine equipped lab. This kit includes Kit # 3 with 80-100 tests.
