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.
Format
EasyMP™ fiber 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
Fibers are derived from cut plastic textiles or ropes and may contain additives present in the original materials. This enhances the environmental realism of the reference material.
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
Oskar has been friendly and effective in ensuring smooth delivery of the order. The color and size range of fibers that were delivered matched the specifications. The inclusion of a pipette for accurate measurement of microplastics made my work smooth. I would recommend EasyMP to those aspiring to work on fibers in the future.
Oscar’s reference materials have been very helpful for optimizing microplastics analysis with Raman spectroscopy. When our clients start developing their methods, they need good samples to practice on and fine-tune their instruments.
Oscar’s materials are perfect for this. They’re easy to use, and there’s a wide selection of polymers, shapes, and colors. This variety is really useful for method validation and helps cover different real-world scenarios.
We highly recommend these materials
Oskar was extremely helpful, and communication with him was seamless. We utilized the provided materials as reference standards to assess the performance of our method for MP identification..
This is a good reference material. We are currently applying both PA and PET fibers in transport studies. We evaluated them through uFTIR imaging, which related well to the information given. For FTIR the small width of the PA fibers can be a challenge, but its great to find materials on a smaller scale. Given that the fibers are delivered in pipett glass bottles, with labeled concentrations, the dosing through out the experiment was made particularly smooth and easy.
Very useful standards (and easy to get!). I ordered some fibers (3x 100 mL EasyMP™: Cotton, PET and PAN) to carry out method validation experiments in our microplastic lab and they perform great. They come in handy glass bottles and are easy to dispense on microscope slides, solutions and filters. I also used them to check and add additional spectra in my infrared (FTIR/LDIR) reference library, so I can better find materials in studies with environmental/forensic samples.
