How to Measure Extract Powders: Micro Scoops, Milligram Scales and Why Density Matters

TL;DR: The little red scoop says 10 to 15mg, but what it actually holds depends on the powder: about 12 to 14mg of our mannitol-carried kanna extract, 20mg or more of a dense resin, and under 8mg of fluffy leaf. Calibrate it once for each extract by weighing ten level scoops on a 0.001g scale and dividing by ten, then use the label percentage to work out the alkaloid content. Keep extracts sealed and dry so the number stays accurate.

We put a little red scoop in almost every extract order. It is a good tool and a bad ruler. The scoop is labeled 10 to 15mg, and it holds 10 to 15mg of one particular powder at one particular density. Kanna extract on a mannitol carrier, a dense lotus resin and a fluffy leaf powder all fill that scoop to different weights. Here is how to make the scoop mean something.

Calibrate the scoop once per extract

You need a scale that reads to 0.001g. A kitchen scale that reads to 1g is useless here. Ours is in the Accessories section and any 0.001g scale works the same way.

1. Put the scale on a flat surface away from fans and vents. Calibrate it with the included weight.
2. Set a folded square of paper on the pan and tare it to zero.
3. Take ten level scoops of the extract and put them on the paper. Level means drag the scoop across the rim of the jar so the top is flat.
4. Read the weight and divide by ten. That is what one scoop of that extract weighs.
5. Write it on the jar. Ten scoops instead of one averages out the small differences between scoops.

On our own shelf a level red scoop of our mannitol-carried kanna extracts lands around 12 to 14mg. A dense resin can be 20mg or more. Fluffy leaf powder can be under 8mg. That is a two to three fold spread on the same scoop, which is why we tell you to weigh it.

Working out the alkaloid content

The percentage on an extract label is the alkaloid content by weight. A 15 percent extract has 150mg of alkaloids per gram, so a 13mg scoop of it carries about 2mg of alkaloids. A 5 percent extract at the same scoop carries under 1mg. This is the number to compare when you switch between extracts, not the scoop count. The percentages guide goes deeper on what the numbers mean.

Read the scale right

• Close the scale lid before reading. Air movement swings a milligram scale by whole milligrams.
• Let it settle for a few seconds. The last digit drifts.
• Tare before every measurement, not just the first.
• Replace the batteries when readings start to wander. Low batteries are the most common reason a milligram scale reads wrong.

Keep the powder measurable

Extract powders pull moisture from the air. A hygroscopic extract that has taken on water weighs more per scoop and clumps, which throws the calibration off. Keep extracts in a glass jar with a tight lid, drop a silica desiccant pack in, and keep it out of light and heat. The lotus resins are the worst offenders. They ship as shards and turn to tacky batter in a warm humid room. That is not spoilage, it is the same material, but you cannot scoop it, so weigh it by the piece instead.

Splitting a bulk order

If you buy 5 or 10 grams at a time, weigh it out into 1 gram jars when it arrives and keep the rest sealed. A jar you open once a day stays dry. A jar you open ten times a day does not.
