Micro Measuring Scoop
Because liquids form a meniscus when dropped into these, it is difficult to say precisely what the volume is, but when weighed on a scale that measures to 0.001 grams, and converted to milliliters, we get the following:
Capacity by Volume: 0.014ml
We've had an opportunity now to use these with a variety of cosmetic ingredient powders and we've noted the average typical weights in below in parenthesis.
Capacity by weight: 6-8mg (average 6mg)
Length: 140mm (5 7/16")
Material: Polypropylene
