Cannabis Testing Equipment & Services

At Conquer Scientific we take pride in selling only the highest quality used and refurbished cannabis testing equipment along with services at affordable prices. We understand that setting up or improving your cannabis testing lab is very important, and sourcing the right equipment is the first step you need to take if you want to achieve great quality in your products that is why Conquer Scientific will give you the necessary resources to help you succeed in this growing market.

We will guide you towards success with our team of experts, providing you with training, method development and establishing quality assurance-quality control (QA/QC) plans along with servicing of the instruments.

Fatih Büyüksönmez, Ph.D., P.E., founder and current CSO of Conquer Scientific and professor emeritus of environmental engineering, is a highly experienced, world-renowned scientist in his field. His background includes research into pesticides, heavy metals, volatile organic chemicals, and terpenes in a wide array of environmental components and agricultural sources. His work with terpenes was recognized with the Research Excellence Award by USCC. Having published extensively in the area, his training and academic experience have provided the insight and knowledge to understand not only the instrumentation, but the science behind lab testing. This is what separates Conquer Scientific from other vendors.

Which Analytical Instruments Will You Be Using?

Cannabis testing Equipment will vary depending on which type of analytical methods you are applying for, specifically, if you want to perform tests most cannabis labs need to run.


Both HPLC and UHPLC methods can be used to determine the cannabinoids.  The advantage of UHPLC is that the sample through put is higher; nevertheless, the cost of equipment doubles.  A cost-effective alternative is the purchase of two HPLCs, this way, a similar sample through put will be achieved; yet, when one system is down for maintenance, the second system still available for analysis

Residual Solvents 

A gas chromatograph (GC) equipped with a FID and headspace sampler is commonly utilized for determination of residual solvents content of extracts.  However, due to separation challenges and non-qualitative nature of FID, a mass selective detector (MSD) is highly desired for Residual Solvent determination.

Residual Pesticides

This is by far the hardest and the most expensive analysis. This is perhaps the testing that many labs fail or struggle to get it done due to either purchase of a wrong instrument or lack of technical expertise of lab personnel.  The issue comes up from the wide array of pesticides with substantially different chemical properties; and gummy nature of the samples; and the potential very low detection limits that the regulatory agency requires.

Microbial Testing 

Cannabis and related products are required to be tested for a set of bacteria (E. coli and Salmonella spp.) and fungi species (A fumigatus, A. Flavus, A. niger and A. terreus).  This can be done using QPCR (real-time PCR) equipment, which has the main advantage of reducing time.

Moisture Analyzers

California is requiring all cannabis to be tested for moisture content and for the results to be printed on the sample’s analysis certificate. This method will help determine THC content if changes in water make results inaccurate. Therefore, moisture analyzers are an easily repeatable and reproducible way to measure water content.

Heavy Metals

While some laboratories employ atomic absorption (AA) or inductively coupled optical emission spectrometer (ICP-OES) for the heavy metals analysis, due to the instrument limitations, we highly recommend use of an ICP-mass spectrometer (ICP-MS).  If your regulatory agency requires testing for Mercury, an ICPMS with a collision cell could be better as it will eliminate the use of gold (minute amount; not a significant cost at all).  So, if an ICPMS without collusion cell used, a gold solution needs to be added to prevent loss of mercury.
