TLC Lab Supply started our business in 2008 and opening our first online store in 2009. We started with a small thin layer chromatography cannabis testing kit we found overseas but it did not really work properly, so we contacted the company that produced the kit and asked if we could bring it to the USA. They decided not to move forward with the product so we took it to another level, we redesigned the functionality of the kit and created easy to use English manual.
