Environmentally relevant microplastic reference materials (microplastic standards) with known quantities and a defined particle size distribution, maintaining less than 20% relative standard deviation per dosage. Suitable for microscopy and spectroscopy techniques. Each sample is uniquely prepared to meet your specifications, with data based on four subsamples from each individual sample, presented in a comprehensive certificate of analysis (COA).
Microplastic fibers are available in various concentrations to meet your requirements.
The standard size range for fibers is 50–1000 µm, but custom size ranges can be prepared upon request. If you need longer fibers or a specific size range, contact us for a quote. Each filament (fiber) has a diameter of 10–20 µm, except for polypropylene (PP)*."
Fibers are available only as EasyMP™ in ethanol (95 vol%.) solution. A single 30 mL or 100 mL sample provides numerous dosages; ideal for supporting a broad range of experiments. All EasyMP™ samples are uniquely tailored to your specifications and come with a comprehensive certificate of analysis (COA), which includes both treated and raw data. The COA can be accessed via the weblink provided upon sample completion or by scanning the QR code on the sample label.

Reviews
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.
