Frequently Asked Questions

Where can I drop off a sample?
Our Eugene Headquarter laboratory is located at 2412 W. 11th Ave, between Jimmy's and the Car Wash in West Eugene. We also have an office in Southern Oregon above Biological Crop Solutions at 4543 S. Pacific Hwy in Phoenix. As of October 1, all sample intake is by appointment only, so you can no longer just swing by to drop off a sample. Please contact us at 541-735-3328 to make an appointment, or for directions.

What are your hours?
We schedule intake between 10am and 4pm Monday through Friday.  We are closed on all major holidays, including Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas, and New Year’s Day.

How do I get an appointment?
There are four things we need from you to schedule an appointment. Our forms are all fillable when downloaded.

  1. Create an account on Confident Cannabis at https://orders.confidentcannabis.com/#!/register?lab=oganalytical
    (**PLEASE DO NOT ENTER YOUR OWN SAMPLES. We will do this for you!!)
  2. Download, read, sign, and return our Terms and Conditions.
  3. Download, complete, and send us a New Account Application.
  4. Complete and send us completed Sampling Request Forms.

Once we have each of these items, we will create an account for you, then contact you to go over the paperwork and schedule your first intake appointment. If you are already a client, we just need the Sampling Request Form.

Why do you need so much information to schedule an appointment?
New Oregon law requires that we take a representative sample according to ORELAP sampling protocols for all compliance analyses. ORELAP sampling protocols are available on the ORELAP website here. The sampling process is complicated and time consuming. Collecting this information prior to your appointment improves our efficiency during the appointment and streamlines the intake process.

What is the sample size required?
Sample sizes are outlined in the above ORELAP sampling protocols. We are required to take 0.5% of the total batch size for any flower product, and our minimum sample size is 5 grams. For concentrates and extracts, the sample size is dependent upon the batch size and varies from 4 to 32 one gram samples. Please read the ORELAP sampling protocols for more information.

What are your fees?
Our fees are outlined in our fee schedule here.

Are you accredited for all required services?
Yes. OG Analytical was accredited to the TNI Standard by ORELAP for all analyses required by Oregon marijuana law, including potency, pesticides, residual solvents, water activity, moisture content, and representative sampling. We received our certificate of accreditation on September 2nd, 2016. More information, including our scope of accreditation, is on our website here.   

How does Batch Testing work?
Batch bagging is an optional, value added service. It is not required by law, but it’s a great way to increase your sales reach. Some buyers require it as a part of their own internal policies. Batch bagging helps buyers ensure chain of custody from the time of sampling until the time of purchase. If you would like for us to batch bag your product, you must separate your batch into the size units you want packaged prior to your appointment. OG Analytical will not be responsible for unit weights. During the appointment, we'll take a representative sample from your batch per the ORELAP sampling protocol, then package your units in our tamper-proof bags. Each tamper proof bag will be pre-labeled with your batch information. You keep possession of your bags; We only keep the sample selected for analysis. When the results are ready, you'll be sent a Certificate of Analysis that you can take, along with your bags, to buyers for consideration. The info on the Certificate of Analysis matches the info on the bags. There is no need to come back to the lab for additional labeling after testing is complete.

What constitutes a "Batch?"
A "Batch" is any amount of usable cannabis product defined by type (e.g. flower or concentrate), strain (e.g. Sour Diesel), production run (i.e. time the product was processed), and production location. There is a ten pound batch size limit for flower as indicated in 333-007-0350.

How soon will the results be ready?
This depends on the type of test you order.  Our standard turn-around time for a Full Compliance test is 7-10 days, depending on our current sample volume at the time the sample is submitted. Please expect delays during the Harvest Season when our sample volume is at its peak.  Edibles, topicals, and glycerin-based tinctures require extra time for sample prep, and are usually completed in 10-14 days.  New or unique products requiring method development will take longer, as well.  Please contact us to discuss timing of new or unique products.

What are your qualifications for running a lab?
Our Lab Director, Dr. Rodger Voelker, has a PhD in plant genetics and over 20 years of analytical chemistry experience. Rodger was the lead chemist in the pesticides department at the ODA (Oregon Department of Agriculture) and has worked as a lead chemist for various dietary supplement and nutraceutical companies. Our laboratory personnel all have a 4 year chemistry degree at a minimum. We also boast over 10 years of accumulated experience in the cannabis industry.  Please visit the Meet the Team page on our website for more information on our qualifications. 

What do you do with unused sample material ("retain") after you've tested my product? Can I have my retain back?
Our policy is to keep all retain for a minimum of 40 days after testing is complete to ensure that we can retest if, for any reason, it becomes necessary to do so. Once that 40 days has passed, all retain gets processed into biohazard waste. We keep a biohazard waste receptical in the lab for cannabis disposal. Our biohazard waste vendor, Sanipac, comes on a regular basis to collect the waste. The state does not allow us to return unused sample material to clients.

Do you offer lab tours?
Absolutely!  We're very proud of our lab, and encourage you to pay us a visit. Our knowledgeable Chemists are happy to walk you through our testing processes, from sample intake to chromatography. 

Do you take credit/debit cards?
Yes. We take Visa, Mastercard, Discover, and American Express. Though we can accommodate cards, cash or check is our preferred method of payment.

If you have further questions, don't hesitate to contact us! Our friendly reps are happy to chat.
