DOUBLE-SIDED SCOOPS: Scoops measure 5-10 mg on one end and 25-35 mg on the other. This may have a wider variance based on your powder's density. Micro scoops can be used for easy dosing of small amounts of powder. These scoops are intended for measuring small amounts of material that are a fraction of a gram (milligrams). There are 1000 milligrams (mg) in 1 gram (g). MADE FOR SAFETY: Have peace of mind with BPA-free, durable, static-free polypropylene material made for food and supplement contact surfaces. MG ML DIFFERENCE: Scoop volume is how much space a powder occupies. Weight changes based on powder density. Two powders may occupy the same amount of space, but could have very different weights. EASY ALTERNATIVE TO MILLIGRAM SCALES: This mg spoon can be used for easy dosing of small amounts of powder. MONEY BACK GUARANTEE: 100% satisfaction guarantee. CAPACITY: 0.005 mL on the smaller end, 0.025 mL on the larger end MADE FOR MG DOSES: The provided weight estimates are intended to be used as approximate guidelines only due to density variation between different powders or other materials. For example, a table tennis ball has roughly the same volume as a golf ball, but they have different weights. When first measuring a new material, please confirm its weight with a 0.001 g (milligram) scale. Conveniently measure milligram amounts of powder with these double-sided scoops. Depending on powder density, 1 side of the scoop will measure between 5 mg and 10 mg, and the other side will measure between 25 mg and 35 mg. These scoops are ideal for supplement powders, nootropics, or lab work. Total scoop length is 2.75 inches.
