Microplastic Reference Material – Environmentally relevant polymer fibers (50–1000 µm)
Synthetic- semisynthetic and natural fibers filaments from raw textile or rope materials. These environmentally relevant materials are suitable for microscopy, spectroscopy, and various microplastic method development and quality control applications.
 
Production
Each batch is produced by cutting virgin macroplastic textile or cordage materials into short fibers and are then sieved and filtered to achieve a defined length distribution. 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 range: 50–1,000 µm
Custom size ranges available upon request.
 
Particle concentration
For EasyMP™ liquid suspensions, you may choose a particle concentration between 100 and 500 fibers(n)/mL. Higher or lower concentrations are also possible – please contact us to discuss custom requirements.
If no concentration is selected within this range, a value will be chosen for you.
 
Color options
Clear/transparent: All fibers are prepared in clear/transparent color option.
Unique color per polymer type: All polymer types (see section Sample Content for details).
 
Format
EasyMP™ reference materials are available in the following formats:
Ethanol (95 vol%)
Water with ethanol (20 vol%) + Tween 20 (0.05 vol%)
Both formulations ensure effective fiber 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 format
 • Provided in 0.25, 0.5 and 1.0 g aliquots.
 • 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
 • Ideal for toxicology studies. Simply pluck the desired amount of fiber and resuspend it in the solution of your choice. We recommend using water containing 0.05 vol.% Tween 20 or Tween 80 as a non-cytotoxic dispersant. Note: Without liquid suspension, fibers tend to aggregate and are difficult to separate.
 
Certificate of Analysis
All samples are accompanied by a sample-specific Certificate of Analysis (COA), based on four subsamples from each batch. The COA includes:
Polymer composition
Fiber length distribution
Number of fibers 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
Please note that our microplastic fibers are sourced from the mechanical processing of textile products and may contain unknown additives or treatments commonly present in synthetic fabrics. Using real-world textile materials helps ensure that our reference fibers are environmentally relevant and reflective of actual contamination sources
 
Shipping
