Microplastic Reference Material – Environmentally relevant polymer beads (10–30 µm, 40–60 µm, 100–140 µm)
Near monodisperse polymer microspheres to meet your analytical needs, suitable for microscopy, spectroscopy, and various microplastic method development and quality control applications. With data based on four subsamples from each batch. All samples are accompanied by a sample-specific Certificate of Analysis (COA), ensuring transparency and reproducibility.
Production
Our microplastic beads are sourced from external suppliers and suspended in solution at Microplastic Solution. Concentrations are quantified in-house using critical angle darkfield (CADFLI) microscopy and image analysis techniques to ensure consistency and traceability.
Particle size range
Standard size ranges:
10–30 µm
40–60 µm
100–140 µm
Custom size selections may be possible on request.
Particle concentration
You may choose a particle concentration within the following standard ranges:
10–30 µm: 400 to 4,000 particles/mL
40–60 µm: 200 to 2,000 particles/mL
100–140 µm: 100 to 500 particles/mL
Higher or lower concentrations may be possible – contact us to discuss your requirements.
If no concentration is selected within the indicated range, a value will be chosen for you.
Format
EasyMP™ bead reference materials are available in two standard formats:
1. Liquid suspensions
Ethanol (95 vol%)
Water with ethanol (20 vol%) + Tween 20 (0.05 vol%)
Both formulations ensure effective particle dispersion. The 20% ethanol + Tween 20 option is not classified as a dangerous good, which helps reduce shipping costs and simplify handling. Pure ethanol may be preferred for applications requiring zero surfactant content.
2. Dry, neat (powder) format
• Provided in 0.5–1.0 g quantities
• Enables long-term storage and flexible resuspension in the solvent or medium of your choice
• Suitable for a wide range of experimental workflows requiring solid-phase dosing or user-defined suspension protocols
Certificate of Analysis
All EasyMP™ samples are accompanied by a sample-specific Certificate of Analysis (COA), based on four subsamples from each batch. The COA includes:
Polymer composition
Particle size distribution within size groups
Number of particles per mL
Treated and raw data, including micrographs from which the data was derived
COAs are accessible via a weblink or QR code printed on each sample label.

Note
Our microplastic beads are sourced from commercial suppliers. Like many plastic microspheres on the market, they may contain unknown additives. We prioritize the use of bead types that closely reflect those observed in environmental samples to improve the relevance of your analyses.
Shipping
Orders are typically prepared within 1–2 weeks of confirmation.
Once shipped, parcels are delivered worldwide via DHL Express, usually within 1–3 business days depending on the destination.
Shipping costs are automatically calculated at checkout based on location and format.

Reviews
The material was successfully identified using Raman spectroscopy and helped me critically to measure the microplastics retention rate in my methods.
Pippetes gave the right amount of material as stated in the excel sheet. The guidelines were easy to follow, and Oscar helped along with the process. The material performed well during filtration, stereoscopic observations, and had clear Raman spectra.
