Particle Capture & Analysis
SiMPore’s all-in-one membrane design simplifies the process: filter the sample and analyze the captured particle on the membrane via multiple forms of spectroscopy, optical microscopy, or scanning electron microscopy.
Our microplastic filters are well-suited for the filtration, capture, and analysis of microplastics from environmental and municipal water samples, air samples, and samples containing suspended solids.
Why Choose SiMPore for Microplastics Research?
Consistent & predictable pore geometry: identical reported porosity, pore size, and pore count across every membrane subsection
Wide range of available pore sizes: explore the particles of greatest interest, from 0.5 to 20.0 µm and larger
Durability across multiple conditions: no need for time-consuming, contamination-prone particle transfer
Rigid, robust design: no additional support structures required
Faster processing and analysis of results: Concentrate particles of interest into a small membrane surface to reduce overall total analysis time
Uniform focal plane across the filter: No membrane wrinkling that disrupt automated particle imaging routines

Our Particle Filtration Materials
Our filters for particle analysis feature a range of filter cut-offs, fast flow rates, and are available with and without metal-coatings for spectroscopy compatibility.
Microslit Silicon Nitride
Microslit Silicon Nitride filters offer rapid flow rates, filtering liters of water in minutes. With a plastic-free, uniform membrane for clear imaging and convenient 25 mm discs compatible with standard vacuum apparatuses, they support customizable filtration cut-offs from 0.5 to 10 µm for precise particle analysis.
Gold-Coated Silicon Nitride
Gold-Coated Silicon Nitride filters combine the benefits of microslit silicon nitride with a highly reflective gold coating, making them ideal for infrared and Raman microscopy. These filters maintain rapid flow rates, precise filtration, and a uniform imaging surface for advanced analytical applications.
