Description
A set of four laboratory micro spoons (micro spoons / micro scoops) with different bowl shapes and capacities, made of a plastic material with antistatic properties. An auxiliary tool for measuring and transferring small amounts of powders and chemical reagents under laboratory conditions. This is an auxiliary tool, not a precision measuring instrument — it has no volumetric graduation and no calibration certificate. A reusable material, intended exclusively for laboratory and analytical work, not for food contact.

Laboratory Applications
- measuring small portions of powders and crystalline reagents for further work;
- transferring substances from a bulk container to a flask, test tube, or weighing boat;
- preparing samples for further analysis, e.g. before dissolution or weighing on an analytical balance;
- working with hygroscopic powders — brief air exposure during transfer limits moisture absorption;
- portioning material between containers when repackaging reagents.
Why We Do Not State Capacity in Milligrams
We deliberately do not declare how many milligrams of a given substance each spoon holds. Three factors make such a figure misleading: bulk density varies between substances by as much as several times over, crystal shape and size affect how tightly the material fills the bowl, and the scooping technique — level or heaped — changes the result by tens of percent. Stating a single “X mg” value would suggest a precision this tool does not have, and for a different substance it would simply be inaccurate.
How to Estimate Spoon Capacity Yourself
For a specific substance, capacity can be estimated through your own measurement. Most laboratory balances in this accuracy class measure with a resolution of 0.01 g (10 mg), and the real error of a single reading can be on the order of ±0.04 g — so a single measurement says little about the actual capacity of the spoon. The solution is to average multiple trials:
- establish one scooping method (e.g. always heaped or always level) and keep to it throughout the measurement;
- perform a series of several dozen repetitions, weighing each portion separately on a clean weighing boat;
- calculate the average mass across the whole series;
- repeat the procedure separately for each substance — a result obtained for one powder does not carry over to another.
The average obtained this way is an approximation valid for a specific substance and a specific scooping technique, not a universal specification of the spoon.
Material, Cleaning, and Maintenance
The plastic’s antistatic properties reduce the adhesion of fine dust to the bowl walls, which makes it easier to work with powders that become charged during pouring and shortens cleaning time between samples. The material is resistant to contact with common organic solvents used in the laboratory and is suitable for repeated use. We have no data on resistance to concentrated acids, bases, or strong oxidizers — when working with such reagents, we recommend testing on a small amount of material beforehand.
Cleaning: distilled water or isopropyl alcohol; for more persistent residues, an ultrasonic cleaner. The spoon must be cleaned each time between work with different substances, to avoid carrying trace amounts of material over into the next sample.
Storage and Work Hygiene
Store in a clean, dry place. If work involves different substances, it is worth assigning each spoon a single permanent use, or thoroughly cleaning the tool between substances — this reduces the risk of carrying over trace amounts of material. Clean the spoon before first use and between substances, as described above. The tool is not intended for contact with food, beverages, or feed and should not be used for kitchen or food purposes.
Product Status and Intended Use
The set of micro spoons is laboratory equipment, not a chemical substance or a measuring instrument within the meaning of metrology regulations — it has no volumetric graduation and no calibration certificate. The material is intended for measuring and transferring powders under laboratory and analytical conditions, for recipients engaged in such activity. It is not a medical device, kitchenware, or an accessory intended for food contact.
Frequently Asked Questions
Are the micro spoons a precision measuring instrument?
No. This is an auxiliary tool for measuring and transferring powders, without volumetric graduation or a calibration certificate. A laboratory balance is needed to determine mass precisely — the spoon is used for transferring material, not for measuring it accurately.
How many milligrams does one spoon hold?
We deliberately do not state this. Bulk density varies between substances by as much as several times over, and the scooping method (level or heaped) changes the result by tens of percent. A method for estimating the capacity yourself for a specific substance is described in the section above.
How do I clean the micro spoons between different substances?
With distilled water or isopropyl alcohol; for more persistent residues, an ultrasonic cleaner can be used. Cleaning between substances is important to avoid carrying trace amounts of material over into the next sample.
Are the spoons resistant to all chemical reagents?
The material is resistant to common organic solvents used in the laboratory. We have no data on resistance to concentrated acids, bases, or strong oxidizers — for such reagents, we recommend testing on a small amount of material beforehand.
What is the purpose of the spoons’ antistatic properties?
It reduces the adhesion of fine dust to the bowl walls, which makes it easier to work with powders that become charged during pouring and shortens cleaning time between samples.
Is the color of the spoons in the set always the same as in the photo?
It may differ — color can vary between batches and is not a functional parameter. The shapes and capacities of the four spoons in the set remain varied regardless of color.
Is the set suitable for working with hygroscopic powders?
Yes. The brief air exposure during the transfer of a small portion limits moisture absorption by the material — this is one of the practical applications of this type of tool.
Are the micro spoons suitable for food contact?
No. The set is laboratory equipment intended exclusively for analytical and research work, not for kitchen or food purposes.
