Infusions you can test 

tCheck's patented technology measures infusions in: 

  • Ghee / clarified butter 
  • Extra virgin olive oil 
  • Coconut oil / MCT oil 
  • Alcohol 

Here is a list of the testing options that we currently support and when you should use them when testing. 

  1. Decarbed Flower Infusion (THC and Hemp mg/ml) – Choose this option if you used some sort of THC or Hemp cannabis plant material to make your infusion.  For example, buds, trim, sugar leaf, or shake.  Please keep in mind that the tCheck device can only test your infusion if the plant material is fully decarboxylated or activated. Please see our blog article on decarboxylation for more details on what that is and how-to decarb.  The next screen will ask you what type of oil was used to make the infusion. Supported base material types for testing Decarbed flower Infusions: Alcohol, Butter, MCT coconut oil, Extra virgin olive oil 
  2. Isolate Infusion (THC and CBD mg/ml) – Choose this option if you made your infusion using some sort of winterized concentrate.  For example:  isolate, shatter, diamonds, crumble, distillate, honey oil (hash oil), or crystalline.  Most concentrates you purchase from a dispensary are winterized, meaning that all of the plant waxes, lipids, and chlorophyll has been removed.  The exceptions to this are FECO, RSO, and rosin which cannot be tested unless winterized.  On one of the subsequent screens, the app will ask you whether the concentrate has been decarbed or activated.  When the infusion is made with a concentrate, tCheck can test whether it has been fully decarbed or not decarbed.  It cannot test material that is only partially decarbed.  The next screen will ask you what type of oil was used to make the infusion.  

Supported base material types for testing Winterized THC isolates: Alcohol, Butter, MCT coconut oil, Extra virgin olive oil, and Winterized CBD isolates: Alcohol, MCT coconut oil, Extra virgin olive oil. 

  1. There may be a bit of confusion between this and the “Concentrate” test.  Choose  
  2. Isolate infusion” if you are testing some sort of oil or alcohol infusion with concentrates infused into it; or 
  3. Concentrate” test if you are testing the concentrate directly and not an oil or tincture. 
  4. Raw Flower (Total Cannabinoid Percentage) – Choose this option if you want to test your raw dried flower before it goes into an infusion.  In order to use this capability, you’ll need the “Flower & Concentrate Expansion Kit” as it has the precision scale and reagents needed to run this test. The result will show the combined total percentage of cannabinoid.  
  5. Concentrate (THCa and CBD) – choose this option if you want to test your winterized concentrates such as isolate, shatter, diamonds, etc.  In order to use this capability, you’ll need the “Flower & Concentrate Expansion Kit” as it has the precision scale and reagents needed to run this test. 

  Notes 

  • Butter and some coconut oils solidify as they cool, and then will not test properly. Make sure your infusion is still in its liquified state before inserting the tray into your tCheck 3.  
  • Samples should be heated on a heating pad or stovetop (NOTE: do not heat the tCheck tray itself). Do not heat any testing material using a microwave, as microwaving can break down certain chemical compounds that will affect the reading. 
  • When measuring butter, please be sure to only use clear butter fats. Milk solids will throw off the measurements. 
  • Alcohol must be clear, and at least 80 proof. Do not use flavored alcohol (you can blend your infusion after testing). Tests will not be accurate with dark alcohol, or flavored alcohol. 
  • Never mix 2 bases together to test. Always make sure to use pure olive oil, butter, coconut oil, or alcohol. Mixing 2 supported bases together to test, or mixing something into the base before testing will nullify results. 

Connecting to your device 

  1. Insert the batteries into your tCheck 3 device, and turn it on. 
  2. Make sure the Bluetooth settings on your phone are enabled. Do not use your phone settings to connect to your device - if you get a pop-up from your phone, just exit out of it. 
  3. tCheck requires Bluetooth low energy (BLE) connectivity to a mobile device in order to function. Apps are available for both iOS and Android. Please download the apps from the respective app stores. 
  4. Log in to the app, or continue as a guest, and click ‘Run Test’ to connect to your device. 
  5. If you have connected to a device previously, the app will attempt to connect to that device. 
  6. A screen will pop up showing the name and ID of your device.  
  7. If your device does not show up, ensure that your device is on and the logo is glowing blue, then tap “Scan”. 
  8. Select your infusion base solvent, and then tap ‘Begin’. 

Running a test 

Remove the sample tray if in the device before powering it on. tCheck performs power-on self-diagnostics and a tray may interfere with these self-checks. 

  1. Place your tCheck 3 device on a flat-level surface and turn it on by pressing the power button. 
  2. Open the sample tray by separating the top and bottom halves. The top half can be identified by the tCheck logo, put this aside for now. 
  3. Place the bottom half of the test tray on a level surface, and place approximately 4-5 drops of infused oil into the circular well area. 
  4. Now place the top half of the tray onto the bottom, it’s OK if a small amount overflows out of the circular well area. 
  5. Ensure that there are no bubbles in the circular well area. 
  6. Follow app instructions to perform a test. 

Test running tips 

 Do not pick up or move the device around with the tray inside it or during a test. tCheck tests best indoors, or out of direct sunlight, as this can affect the accuracy of your results. 

  • Shake your infusion before putting 3-5 drops into the bottom half of the tray. 
  • To avoid an infusion from solidifying in the tray, wait until you are prompted to insert the tray before putting an infusion inside the well. 
  • Make sure there are no bubbles or solid material (such as tiny plant pieces) inside the testing tray once you have put the top and bottom pieces together. Anything solid in the tray will nullify the results. 

Measurement range & accuracy 

Measurement ranges for butter, coconut oil/MCT, olive oil, and alcohol are: 

THC/CBD  

  • Olive Oil: 1 ~ 15 mg/ml  
  • Butter/Ghee: 1 ~ 15 mg/ml  
  • Coconut/MCT Oil: 1 ~ 15 mg/ml  
  • Alcohol Tinctures: 1 ~ 15 mg/ml  

THCa  

  • Flower: 1 ~ 40%  
  • Concentrate: 1 ~ 99%  

Interpreting your results 

After the test is complete, your results will be displayed in mg/ml — milligrams of cannabinoids per milliliter of oil. CBV means “Compounds by Volume” which represents the total amount of cannabinoid molecular content per volume of liquid. This display may be changed to show other units such as mg/tsp or mg/tbsp. 

An analogy would be dissolving sugar in a cup of water. If someone gives you a cup of sweetened water, CBV is a measure of the amount of granulated sugar that was dissolved in that cup of water. For example, 1 tbsp of sugar into 1 cup of water. (Note: tCheck does not measure sugar) 

You can now take your test results and use them in the CBV Calculator to adjust your recipe accordingly. 

Getting an 'OVER' measurement 

The result displayed as ‘OVER’ means that the infused potency is stronger than tCheck is able to measure. 

  1. Measure out a precise volume of your infusion (for example .5 mL). 
  2. Measure out 2x the volume of the uninfused base oil (if you first measured out .5 mL, you would measure out 1 ml of the uninfused base). 
  3. Mix thoroughly. Proper mixing is vital to getting an accurate reading. Use tCheck to measure the potency of the diluted solution. 
  4. Multiply the measurement reading in mg/ml form by 3. This is the potency of your original infusion. Be sure to use this final amount you have calculated when dosing. 
  • Avoid diluting the solution in the testing tray. 
  • Shake the dilution to mix it thoroughly.

Taking care of your device & tray 

Turning off your device 

tCheck automatically powers down after 3 minutes of inactivity so there is no need to press the power button to manually power down the device. To re-awaken the device, simply press the front power button (do not hold the button down). With normal use, a set of AAA batteries should last over 4 months, running several hundred measurements. 

Taking care of your device 

  • Do not immerse or submerge the tCheck device. 
  • Hand wash sample tray & swizzle sticks with a soft sponge and liquid household dish soap. 
  • Never store a used tray or clean tray in the tCheck unit. Always remove the tray and store both the tray and tCheck in a clean, dry place. Try to keep your tCheck device free of internal dust. 
     

Taking care of your tray 

Important! Even minor damage to your tray can lead to incorrect results. In the event that a new tray is required, you will need to return your device for recalibration. 

  • Your tCheck tray, if properly cared for, should last the life of the device (roughly 1,000 tests). 
  • Hand wash tray after each test, with non-abrasive cleansers. Wipe and dry it with a soft cloth. 
  • Washing the tray in the dishwasher will destroy it. 
  • Do not allow boiling hot liquids to touch your tray. 
  • If the infusion solidifies in the tray before running a test, you will need to wash it and start over. 
  • Do not handle your tray unless your hands are clean. Certain lotions, essential oils, and other contaminants can cloud and damage the tray. 
  • Do not set your tray down on a hot surface. 

Immediately after you are satisfied with your testing results, gently hand wash your tray with dishwashing liquid (i.e., Dawn). Never place your tray on a hot surface or put it in the microwave or dishwasher. This will damage your tray and bring great sadness to your tCheck 3 device.

Turn on your scale and allow it to zero itself. You can always re-zero the scale by pressing the tare button. If the scale was tared without the metal sample dish, you must re-tare the scale if you place the dish on the scale. 

Mode/Units 

This scale can display the weight of your material in several different units. 

 Setting Scale to grams 

After you have tared your scale, put it on the ‘g’ setting. 

Note that the tCheck app takes input in terms of milligrams (mg) which is 0.001 g. On your scale, 100 mg would display as 0.100 g. 

Scale Notifications 

  • Battery icon-Replace batteries 
  • “FULL” display — Maximum capacity exceeded (>20 grams) 

Scale Specs 

  • 3 minutes to auto-shutoff 
  • Operation Temperature: 60 ~ 100 (15 ~ 38
  • Backlight: Blue backlight 
  • Power: 2 x AAA Batteries 
  • Size: 99 x 88 x 25 mm 
  • Weight: 105g 
  • Size of stainless steel pan: 34 x 34 x 5 mm 
  • Tare function 

Taking care of the scale 

  • Take off the cover carefully when using the scale. 
  • Do not put heavier objects than the capacity of the scale. This can damage the load cell. 
  • Do not strike or hit the plate of the scale. 
  • When the scale shows the battery mark, please replace the battery immediately. 

Testing Raw Flower 

  1. Collect one sample container, stirring stick, reagent, 10 mL syringe, a 1 mL syringe, and filter. 
  2. Weigh out between 100–250 mg of flower (a pea-sized amount) and place it on the scale. The metal sample dish is helpful if the sample is crumbled or in multiple pieces, but that is optional. 
  3. Record the weight of your sample. If you record this correctly, it will ensure your results are valid. 
  4. Remove the lid on the sample container, and carefully put your cannabis flower into the container. Use the swizzle stick to break up the flower gently. Ensure that no plant material is stuck to the swizzle stick. 
  5. Using the 10 mL syringe, draw precisely 10 mL of reagent and slowly push it into the sample container with your cannabis. Screw the lid onto the container and ensure it is sealed well. Shake it for 4-5 minutes. 
  6. Allow the sample liquid to settle for a few seconds. Use the 1 mL syringe to draw approximately 0.5 mL of infusion without the filter.*  

*Do not test your sample infusion after 6 minutes. Your test results will not be valid if cannabis sits in the reagent for longer than 6 minutes. Dispose of it accordingly. 

  1. Attach the filter to the nozzle of the filled 1 mL syringe. Insert approximately 0.25 ml (4 to 5 drops) of the infusion through the filter and into the indented well on the bottom tray on a flat, level surface. 
  2. Close the tray by placing the upper half of the lid onto the bottom portion, ensuring no bubbles are visible. A small amount of liquid may squeeze out of the circular measurement area. There should be no floating plant material in the sample. If bubbles exist, open the tray and add more filtered analyte. 
  3. Turn on your tCheck device and ensure Bluetooth is enabled on your mobile device. Then, open the tCheck app and click the “Run Test” button at the bottom of the screen. 
  4. At the Select a Device screen, click on the serial number that appears. Select the “Raw Flower” option to begin testing. Follow the onscreen instructions in the app to complete your flower test. 

Note: We recommend testing multiple samples in your batch of plant material. Plant potency may be affected by factors such as residual water content, harvest cycle (1st harvest, 2nd harvest, etc.), part of the plant, maturity of the bud, etc. Testing multiple samples in your batch and taking the average will provide a more representative understanding of your material. *Moisture content in the flower material will cause the % reading to go down. The amount of cannabinoids will be the same. However, because the result is shown as a percentage (mg/mg), the flower's denominator or weight will increase, reducing the result. 

Testing Winterized Concentrate 

  1. Collect one sample container, stirring stick, reagent, 10 mL syringe, a 1 mL syringe, and filter. 
  2. Weigh out between 30–110 mg of concentrate (about the size of a grain of rice, depending on the type of concentrate) and place it directly into the metal dish on the scale. We recommend using a sample spoon if the concentrate is sticky or difficult to handle. If the sample spoon is to be used, be sure to tare the scale with the spoon before you collect your sample for a more accurate sample weight. 
  3. Record the weight of your sample. If you record this correctly, it will ensure your results are valid. 
  4. Remove the lid to the sample container, and carefully put your concentrate directly into the container. If your concentrate is on the sample spoon, put the entire spoon into the container. 
  5. Using the 10 mL syringe, draw 10 mL of reagent precisely and gently expel it into the sample container with your cannabis. Quickly replace the lid on the container and ensure it is sealed well. Shake it for 5 minutes or until the sample is completely dissolved. 
  6. Allow the sample liquid to settle for a few seconds. Use the 1 mL syringe to draw approximately 0.5 mL of infusion without the filter. 
  7. Attach the filter to the nozzle of the filled 1 mL syringe. Insert approximately 0.25 mL (4 to 5 drops) of the infusion through the filter and into the convex well of your tCheck tray bottom on a flat, level surface. An exact amount is not necessary. 
  8. Close the tray by placing the upper half of the lid onto the bottom portion, ensuring no bubbles are visible. A small amount of liquid may squeeze out of the circular measurement area. 
  9. Turn on your tCheck device and ensure Bluetooth is enabled on your mobile device. Then, open the tCheck app and click the “Run Test” button at the bottom of the screen. 
  10. At the “Select a Device” screen, click on the serial number that appears. Select the “Winterized Concentrate” option to begin testing. Follow the onscreen instructions in the app to complete your concentrate test. 

Interpreting your results 

The results will be a percentage of cannabinoid content. Once you get your test results, you can add notes about your sample, including strain type, extraction method, etc. Notes can help you keep track of what you tested and when. Results and notes are stored in the Log section of the app.
