Microplastic Beads
10-30 µm | 40-60 µm | 100-140 µm
Micro-spheres or "beads" are popular tools in microplastic research due to their affordability and because they are easy to control and identify. Their uniform size and composition make them ideal for studying the transport and fate of microplastics in various environments, in a controlled manner. Micro-beads present the first step to advancing our understanding of the complex dynamics associated with microplastic pollution.

Microplastic beads are useful tools in research
We prepare samples of known quantities of beads in various size ranges from 10 µm and upwards, in a wide range of polymer types and colors. Save your time and effort and let us do the counting for you. Microplastic beads are useful tools for beginners and experts alike. Our assorment includes beads from 10-30 µm, 40-60 µm and 100-140 µm.

Stage a simple but compliant recovery experiment
EasyMP™ beads comply with: ISO 16094-2:2025 and Directive (EU) 2020/2184
Step #2: Manually count the precise number of particles using the counting-freeware ClickMaster2000.
Step #1: Vacuum filtrate red PE beads (10-30 µm) onto a 25 mm PVDF or PTFE membrane.
Step #3: Flush the beads from the filter membrane into your matrix, and conduct the complete sample pre-treatment protocol.
Hint: To skip steps #1 and #2, spike your matrix directly using the EasyMP™ solution, but accept ~20% RSD in dosage quantity.
Step #4: Following completion of the pre-treatment protocol, once again, using ClickMaster2000, count the total number of of successfully transfered re PE beads.
Step #5: Conduct at least three replicate experiments.
The recovery rate of your protocol is determined as the average recovery of all your replicate experiments.
Tip: We recommend correcting any acquired environmental microplastic data using the established recovery rate.
Subsample #1
RR = 78%
Subsample #2
RR = 73%
Subsample #3
RR = 81%
Mean recovery rate (RR) = 77% (n = 3)
This example illustrates a recovery experiment of sufficient quality to meet the requirements of standards such as ISO 16094-2:2025 and Directive (EU) 2020/2184.
Although this relatively simple recovery experiment is easy to perform and complies with current norms, it does not provide insight into the relationship between particle size and recovery rate.
For more advanced and insightful recovery experiments, consider using microplastic fragments or fibers, or a combination of beads with different sizes and colours to facilitate discrimination.
