GemmaCert - Cannabis Analyser: Cannabis Testing Made Simple

The GemmaCert offers a revolutionary way to test weed. Growers, dispensaries, and customers can now measure THC and CBD levels at home or at the store using GammaCert and a smartphone.

The designers of the device hope to bring transparency and decentralised testing to the cannabis world. Growers used to have to send batches of bud off for expensive laboratory testing. Not only was this expensive, but samples had to be destroyed during the process.

The GemmaCert is posed to change the game entirely. The machine only requires a small sample—a single bud—and doesn’t damage the contents. Plus, it doesn’t cost a fortune every time you want to find out the major cannabinoid content of your crop.

The creators behind the device have also pointed out the rampant mislabelling of cannabis flowers on the current market. It’s in the interest of recreational and medicinal users to know exactly what they are buying. Dispensaries often mislabel buds because of poor testing procedures or skip testing altogether. The GemmaCert device offers a way around this. Cannabis users, sellers, and growers can now test for THC and CBD levels on a desk or kitchen countertop.


The patent-pending device gathers spectral data from flower samples and generates results in less than a minute. Optical sensors scan dried or ground flowers that are inserted into the device. The spectra of the sample is collected and analysed by the GemmaCert cloud server. Shortly after, the accurate composition of THC and CBD levels is sent to the user's smartphone.
