Purpl PRO Bench

Purpl PRO is the flagship product offering by Purpl Scientific, and the first affordable, accurate, portable potency measurement device for the industry. It is a combination of a "laboratory bench" device the size of a hockey puck and a mobile app that allows users to run the system through a smartphone

Purpl PRO utilizes near-infrared spectroscopy, which involves shinging light on the sample and analyzing the light that is returned. In this part of the light spectrum (just beyond the red light human eyes can see) molecules react to specific regions of the light to generate a "molecular fingerprint" that can be correlated with concentration. The Purpl PRO was calibrated against HPLC measurements from multiple state-certified testing laboratories.

Purpl PRO App works with:

  • Apple iOS version 11.0 and later
  • Android version 5.0 and later

Use Cases


Cultivators turn a seed into a sellable crop, and have many decisions to make each step of the way. But the end goal is to make a consistent, high quality product that commands the best profit. Big agriculture uses a lot of analytical technology to achieve the same ultimate aims, but not all of that technology has made its way to cannabis cultivation. Purpl is based on the same technology used in agriculture (and pharmaceuticals) to instantly provide chemical information that helps optimize your crop. With Purpl, that technology allows you to instantly measure potency in dry flowers, and soon in growing plants. You might want to measure buds from different parts of the same plant to optimize your lighting setup. Or know which part of the field is producing your desired potency target. We’re sure you can come up with multiple other ways a Purpl would help you optimize your production.



Distributors connect the cultivators to the retail dispensaries, with an impetus to get best pricing and a consistent product. Lab tests are available on the crop, but with a natural product like cannabis there is a lot of variation, and that batch being bought or sold might not be the same as what was tested. Purpl helps provide transparency on both sides of the transaction, and it uses technology that’s been used by big agriculture for decades to ensure crop quality and consistency. Instantly measuring potency allows distributors to verify the consistency within a batch, or how it measures up to the last batch, to maximize negotiating power and maintain a quality product.



Infused product manufacturers require instant insight into potency and composition. Purpl PRO provides that intelligence. While lab tests are necessary for the end product potency, consistent quality is still difficult to achieve if there’s any variability in the feedstock. Purpl PRO allows MIP producers to measure the exact batch in much the same method as how big agriculture and food manufacturers use this same technology. Dial in the precise dosage by knowing exactly what’s going into each batch, so you can be sure the final product will be on spec.



Extraction strips cannabinoids away from the plant matter, allowing the creation of purified waxes and oils. Consistency is paramount in order to create a successful product. However, extraction has many variables, from the incoming trim feedstock to the pressures, temperatures, and many other variables. Labs can verify the potency of the finished batch, but it’s a lot more helpful and cost-effective to be able to make instant decisions to optimize each batch and avoid any unexpected surprises. Purpl PRO lets you verify the potency of the specific trim you’re using, to help you custom-tailor each batch. Purpl PRO will soon be adding extract potency measurement, to allow the same closed-loop controls that are used in other industries, like big agriculture, food production, and pharmaceuticals, who already benefit from this same technology.



Dispensaries are the retail link in the industry, sourcing product from distributors or cultivators for sale to their customers. The goal is repeat business and increased sales, which hinge on consistent, quality products. Lab tests provide a general idea of the crop, but in a natural product like cannabis there’s a lot of variation from bud to bud, plant to plant. Purpl allows dispensaries to instantly test potency in flowers, and soon in extracts. That means knowing exactly what is being purchased, to negotiate the best pricing with suppliers. And customers will have the ability to measure exactly what they’re buying, so they know exactly what to expect.



As a consumer, you want to know what you’re ingesting. Maybe it’s the maximum effect of a highly concentrated strain you’re after. Or perhaps you want to ensure there’s nothing in your CBD. Knowing the exact potency is key to appropriate dosing. Even when you see the lab-tested potency for the product you bought, the results were determined from another flower or plant, and as natural product, each plant and even flower has a lot of variation. Purpl PRO has transformed the technology used for decades by big agriculture, into an affordable, easy-to-use device that lets you test exactly what you’ve got, so there’s no more worrying what to expect.

Purpl Scientific Purpl PRO Potency Measurement System Reviews

Good accuracy
We have used this in our office with testing potency of personal grows as a competition with each other's flower as well as testing many of the clubs flowers that was already tested and I'm very impressed with how well this works.

Just make sure to keep it clean and calibrated to get consistent results. Good buy for hemp growers looking to keep their product under 0.3% per regulation.

Best value compared to other super expensive options. This is a better buy for most people.
