Where are you located?
We are currently located in Santa Cruz, CA.

What is your Turn Around Time for Sample results?
Deibel Bioscience has the goal of providing a 3 to 5 business day turn-around time for both R&D and Compliance samples; the Turn Around Time “clock” starts for all samples received by 3pm that day. We offer “Rush” services and “Critical Rush” on most testing but speak to the lab to ensure they can accommodate the Rush or Critical Rush testing when making the request. Most of our labs operate 365 days a year, seven days a week.

What are the current state regulations for Cannabis?
With the passage of the Medical Marijuana Regulation Act (MMRSA) in 2015, Cannabis businesses in California are now subject to specific requirements including licensing, taxation, and mandatory laboratory Quality Assurance testing. Deibel Bioscience can help you understand the required analyses, and acceptable limits for Category I & II Pesticides, Category I & II Residual Solvents, Microbiological Impurities and cannabinoid potency and profiles, and much more.

Do I have to use a third-party testing Laboratory?
Yes. In all States where Cannabis is legal (for medical or recreational), States have implemented regulations that stipulate the use of a licensed laboratory for the required testing. This Lab license cannot be given to a company or individual that owns an interest in related cannabis business (i.e. a dispensary, cultivation facility or processing center).

What equipment do you use for our samples?
To meet the demand of our clients for accuracy as well as fast turn-around times, Deibel Bioscience has invested in state-of-the-art testing equipment. We have enough redundancy to meet our clients’ needs for accurate data that you can trust and fast turn-around times. We’ve selected equipment from the top manufactures in the industry, such as PerkinElmer, Agilent, and Shimadzu

Why we use Liquid Chromatography (LC) instead of Gas Chromatography (GC)?
We have invested in High Performance Liquid Chromatography (HPLC-UV) to screen for cannabinoids because it allows us to detect the acid compounds as well as the neutral states, something a Gas Chromatography machine cannot perform.

How is Deibel Bioscience different from other labs?

Deibel Labs, Inc. began in the early 1960’s and was one of the first contract Food testing labs in the United States. We have since grown to 14 strategically located labs across North America and are proud to announce our latest testing division for the Cannabis Industry, Deibel Bioscience, LLC. We currently operate out of Santa Cruz, CA and Chicago, IL, Hood River OR. Labs with more locations coming online in the future.

At our level in the industry, any lab should be able to offer accurate testing, at a fair price and a reasonable turn-around time. These three qualities are no longer defining features; rather it is our high level of service and exceptional Technical Services acumen that set us apart. Drawing on decades of experience in the food testing industry, we offer the highest level of technical expertise in the business.

We have made significant investments in testing equipment and people to bring industry leading turn-around times to the Cannabis Industry.



Do you offer pickups?
Deibel Bioscience maintains a fleet of courier vans for the pickup and sampling of cannabis samples. In California, all regulatory compliance test samples must be taken by an associate of the testing laboratory using validated methods to ensure that the sample is representative of the production batch produced.

Currently, we offer an extensive courier pickup service to clients in California across the State. A trained Field Technician must obtain the physical samples for all Compliance testing, but the client may “drop off” any R&D samples if that is desirable.

Can I send you my samples?
Clients are welcome to drop off non-compliance samples in person but only if they are R&D samples. Products for sale must be sampled by a laboratory associate at a licensed distribution facility. Each compliance package we offer has unique sample-size requirements, as does the individual tests for non-compliance testing of individual assays, but roughly speaking we need at least 1 gram of product for each test listed in Table 1 in the “Testing and Regulatory Compliance” section below.  

What is the recommended Sample Size?
If you’re submitting a sample for a full compliance package, the sample size requirements are dependent upon the original Batch/Lot size. The field technician will collect the minimum sizes below to ensure a representative sample sufficient for the state’s testing requirements; however, for batches/lots larger than the sizes listed larger sample sizes will be required:



State Testing Requirements  Cannabis (Flower)  Cannabis Concentrate Cannabis Products
CA Testing  17 g – 79 g
(Up to 50 lbs. Batch size)
23g 23g

You must submit samples in a sterile sample container, to avoid any potential for microbial contamination. You can purchase sterile sample containers from our lab or use your own. We are happy to offer guidance on appropriate sampling containers, just ask!



What test do I need for my samples?The State of California has a written code that delineates all cannabis activities conducted in the State called Title 16 of the California Code of Regulations.  The Bureau of Cannabis Control (BCC) was established to regulate and inforce the Title 16 regulations. The testing on cannabis and cannabis products has established (16 CCR 5715) phase-in of all required testing:




What are Microbial Impurities?

Various States have adapted different requirements for Pesticides testing in Cannabis, but all
originate from EPA protocols for environmental pesticide analysis.

 A sample of inhalable cannabis or inhalable cannabis product shall be deemed to have passed if the following are met:

Shiga toxin-producing Escherichia coli is not detected in 1 gram;

Salmonella spp. is not detected in 1 gram; and

Pathogenic Aspergillus species A. fumigatus, A. flavus, A. niger, and A. terreus are not detected in 1 gram.


A sample of other cannabis or cannabis product shall be deemed to have passed the microbial impurities testing if:

Shiga toxin-producing Escherichia coli  = not detected in 1 gram, and

Salmonella spp.  =  not detected in 1 gram.


Why we use Liquid Chromatography (LC) instead of Gas Chromatography (GC) We have invested in High Performance Liquid Chromatography (HPLC-UV) to screen for cannabinoids because it allows us to detect the acid compounds as well as the neutral states, something a Gas Chromatography machine cannot perform. The difference in the equipment investment for HPCL-UV versus GC is significant. Gas Chromatography (GC), an alternative method widely used for cannabis analysis, uses heat during the analytical process, causing the acids to break down. Because these acids breakdown during analysis, a GC is unable to give an accurate picture of acid forms; the precursors to THC and CBD. This makes it inappropriate for testing products that will not be heated prior to consumption, such as edibles and tinctures, and limit its ability to accurately identify the acid forms (THCA, CBDA, CBGA). HPLC, on the other hand, uses high pressured liquid and alcohol solvents which don't require heat and therefore don’t alter the cannabinoids during analysis.


What Pesticides do you test for? Various States have adapted different requirements for Pesticides testing in Cannabis, but all originate from EPA protocols for environmental pesticide analysis. 

California Category I and II Pesticide Screening - Includes all 66 compounds required by the state beginning July 1st, 2018. Category I pesticides are not allowed at any level; Category II pesticides have certain allowable limits.

California Category I Pesticides Include 21 compounds all with a zero tolerance. These compounds include Chlorfenapyr, Chlorpyrifos, Coumaphos, Daminozide, DDVP (Dichlorvos), Dimethoate, Ethoprop(hos), Etofenprox, Fenoxycarb, Fipronil, Imazalil, Methiocarb, Methyl parathion, Mevinphos, Paclobutrazol, Propoxur, Spiroxamine, Thiacloprid.

California Category II Pesticides have certain allowable limits.  This list includes Abamectin, Acephate, Acequinocyl, Acetamiprid, Azoxystrobin, Bifenazate, Bifenthrin, Boscalid, Captan, Carbaryl, Chlorantraniliprole, Clofentezine, Cyfluthrin, Cypermethrin, Diazinon, Dimethomorph, Etoxazole, Fenhexamid, Fenpyroximate, Flonicamid, Fludioxonil, Hexythiazox, Imidacloprid, Kresoxim-methyl, Malathion, Metalaxyl, Methomyl, Myclobutanil, Naled, Oxamyl, Permethrin, Phosmet, Piperonylbutoxide, Prallethrin, Propiconazole, Pyrethrins, Pyridaben, Spinetoram, Spinosad, Spiromesifin, Spirotetramat, Tebuconazole, Thiamethoxam, Trifloxystrobin.


What are (Residual) Solvents and do you test for them?Increasingly, more and more patients and consumers are seeking concentrated forms of Cannabis (i.e wax, budder, amber glass, shatter, etc.). These types of concentrates are produced by using a solvent (such as CO2, Butane, ethane, propane, etc.) to extract cannabinoids from the flower. Heat is typically used to remove the solvent from the concentrate, but trace amounts can be left behind that may be harmful. 


The California Bureau of Cannabis Control has two levels of Residual Solvents required for testing in appropriate sample matrices, as of July 1, 2018.  A sample shall be deemed to have passed the residual solvents and processing chemicals testing if both of the following conditions are met.  Similar to the Pesticides Category I Residual Solvents have a zero tolerance and Category II have certain allowable limits.



How do you report results?

All Cannabis Laboratory functions are controlled and monitored through a Laboratory Management Information System or LIMS.  The LIMS system we use across our network is compliant to CDC, FDA, USDA and State Cannabis Regulations.  The LIMS system is audited annually by clients as well for ISO 17025:2017 Accreditation for data security and compliance.

California Clients: The Bureau of Cannabis Control has limited what can be shared with cannabis clients.  Specifically, “The bureau’s regulations do not permit the reporting of any results prior to the completion of analyses, nor prior to the release of the regulatory compliance COA. Laboratories are not permitted to release results as they become available via an online portal or any other type of notification. (For example, it is not permitted to allow the requester to access or notify them of results upon completion of each individual analysis— cannabinoid, pesticide, microbial testing, etc.)” - August 24, 2018 New Fact Sheet from BCC

For a copy of the full Lab Fact Sheet from the BCC, please contact your local Deibel BioScience and they will be more than happy to send you a copy.


Deibel BioScience utilizes a unique Formal Report for all cannabis and cannabis related products.  This Formal Report is reviewed by Laboratory Management, then submitted electronically to our clients via email or fax.  Additionally, all data for individual samples as well as the completed Formal Report can be viewed and downloaded through a secure Client Web Portal using a unique username/password.  To get setup on the Web Portal, please contact your Lab Manager or Sales Associate.


For California clients, the BCC mandates that the lab send a copy of the Formal Report to them within 24 hours of all testing being finalized.


Can I view my results on line?

Yes.  All data from individual samples, as well as completed Formal Reports can be viewed through a Client Web Portal.  You can search for individual batches, send reports to others through the secure connection, as well as perform trend analysis for historical data to see how your results have changed over time.


For California clients, only the completed Formal Reports are available for compliance testing; labs are not allowed to notify clients for any test that failed, either through an online web portal or through phone/text/email.  Only the final compliance COA can be sent once all testing is completed. However, once a compliance COA is finalized after all testing is done, it can be posted on our client web portal as well as emailed to both the client and to the BCC.  Through this web-portal, you can send these COAs to others.


How do you report Out of Specification (OOS) results?

For California R&D samples you will receive a Service Call from the lab as soon as the OOS is obtained by the lab as long as you have provided the Lab with a list of the samples’ specifications (i.e. “Potency should be 80-85%” as you would record on the SARF that is sent along with your samples).  Service Calls are a program Deibel Labs started over 20 years ago as a mechanism to quickly notify our clients of any adverse test result.  These are given out by our chemists and microbiologists who have first-hand knowledge of your samples.  This is a great mechanism to be able to ask them technical questions. If you need additional technical advice, the chemist or microbiologist will get a member of our Technical Services Group on the phone so you can get the answers you need.


For California Compliance Samples, the BCC has mandated that labs are not allowed to notify clients of an OOS result until the entire compliance testing is completed and the Formal Report is sent to the client and to the BCC.  For R&D samples, there is no BCC reporting mandate, so you should receive a Service Call from the labs for any OOS result. 



Deibel Bioscience of California is ISO 17025:2017 accredited and licensed with the California Bureau of Cannabis Control.
