Expansion Kit User Manual

The flower and concentrate testing kit extends tCheck’s capabilities to measure:

  • Buds * mature dried flowers
  • Trim / Shake *manicure
  • Full Extract Cannabis Oil (FECO)
  • Wax / Crumble
  • Shatter
  • Resin / Rosin

The kit includes:

  • Precision scale
  • Three (3) mixing tubes
  • Pestle (swizzle stick)
  • 100ml bottle of reagent
  • 10ml syringe
  • Plastic spoons
  • Eye dropper

How to use precision scale

To ensure accurate readings of your flower and concentrate potency, tCheck has provided a verified precision scale.

  1. Place scale on a flat surface
  2. Press “ON”, wait a few moments until the scale shows “0.0”
  3. Use “MODE” to cycle through the measurement units until “g”, or grams
  4. If value is greater then “0.0” before adding material, press “TARE” to correctly zero the scale (For instance, when using the larger plate for measuring)
  5. Place the sample material on the scale to get your sample reading
  6. Press “off” to turn off the scale

How to calibrate scale

  1. Press “on”, wait until the screen shows “0.0” reading.
  2. Press and hold “on” again for 3 seconds or until the screen displays “0”, then release the button.
  3. Wait until the unit value “g”, in the top right corner of the screen, is flickering.
  4. Place a weight onto the plate (a weight the scale can handle)
  5. Give it a few seconds as the scale calibrates and when the unit value “g” stops flickering, the scale is calibrated.

Scale Specs

  • 3 minutes to auto shut off
  • Operation Temperature: 60℉ ~ 100℉ (15℃ ~ 38℃)
  • Backlight: Blue backlight

Taking care of scale

  • Take off the cover carefully when using the scale.
  • Do not put heavier objects then 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

How to test plant material (buds, trim, ABV)

Much like the HPLC (High Performance Liquid Chromatography) instruments used in commercial testing labs,
tCheck requires the sample be prepared for testing. This involves weighing the sample, mixing it with a reagent, then measuring the mixture.

  1. Ensure the scale is properly zeroed.
  2. Using the scale, measure out approximately 100mg of the plant. It doesn’t need to be exactly 100mg but be sure to note down the final weight.
  3. Put the plant material into the mixing tubes
  4. Using the swizzle stick pestle, finely crush the plant material
  5. Using the syringe, measure out exactly 10ml of reagent and pour into the mixing tube with the plant material
  6. Seal the mixing tube and shake. Ensure that the seal is very good to ensure that none of the mixture leaks. Allow the mixture to steep for at least 5 minutes, occasionally shaking.
  7. After 5 minutes, allow the mixture to settle. If some plant material is still floating, give a quick shake and allow to settle again.
  8. Using the eyedropper, extract approximately ⅓ of an eyedropper full of the extraction. Ensure that plant material is not picked up as solids in the sample tray will throw off your measurements.
  9. Place 5 drops of the extraction into the your testing tray
  10. On the mobile app, select ‘Flower’ test and follow the on-screen instructions.

Notes

  • 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 denominator, or weight of the flower will increase, reducing the result.

How to test concentrates (FECO, shatter, crumble, etc.)
Much like the HPLC (High Performance Liquid Chromatography) instruments used in commercial testing labs, tCheck requires the sample be prepared for testing. This involves weighing the sample, mixing it with a reagent, then measuring the mixture.

  1. Using the scale, measure out approximately 50mg of the extract. It doesn’t need to be exactly 50mg but be sure to note down the final weight. Because concentrates can be very sticky and difficult to manage, plastic spoons can be used to pick up samples. Be sure to zero (tare) the scale with the spoon.
  2. Place the spoon with the concentrate into the mixing tube.
  3. Using the syringe, measure out exactly 10ml of reagent and pour into the mixing tube with the concentrate
  4. Seal the mixing tube and shake periodically until concentrate has fully dissolved. Ensure that the seal is very good before you start shaking to ensure that none of the mixture leaks.
  5. Using the eyedropper, extract about ⅓ of an eyedropper of the extraction.
  6. Place 5 drops of the extraction into the your testing tray. Put the top tray on quickly, to avoid evaporation of the reagent.
  7. On the mobile app, select ‘Concentrates’ test and follow the on-screen instructions.

Notes

  • Some extraction methods may allow for the possibility of plant matter mixed into the concentrate. For the most accurate measurements, it is recommended that the carrier solvent is well filtered before distillation, or ensure that all plant matter has settled to the bottom before removing liquid to place in the tray for testing.
  • Ensure that the reagent bottle is tightly closed when not in use. When exposed, the reagent will evaporate over time.

Interpreting your results
When the measurement is complete, your results will be displayed as a percentage of cannabinoids by weight. This is similar to the results you would see on other commercially produced concentrates.

Important Safety Considerations

  1. Read all instructions before using the test kit
  2. DO NOT CONSUME THE REAGENT. Please see MSDS for details. Dispose of properly.
  3. DO NOT INHALE THE FUMES FROM THE REAGENT.
  4. Once the testing is complete, remove tray and hand wash to clean the tray out. If left in the tray, the reagent will damage the tray.
