Membrane Filter

Mesh Filter

Mesh Filters are designed for prefiltration and clarification of solvents and solutions containing large suspended solids. Made from woven monofilament nylon or 100% virgin polypropylene, they offer large pore sizes from 10 to 180 µm and broad chemical compatibility. The precise mesh opening, open surface area, and consistent thickness ensure reliable particle retention and flow performance across diverse analytical and industrial applications.

Large pore sizes from 10 to 180 µm allow efficient removal of coarse particulates without clogging
Woven monofilament construction provides consistent mesh opening and mechanical strength
100% virgin polypropylene and nylon materials ensure broad chemical compatibility with solvents and samples
High open surface area (up to 87%) improves flow rate and reduces pressure build-up

Comparison

Compared With The Alternatives

Versus Microfiltration membranes

Mesh filters have larger pore sizes and higher open area, making them better for coarse prefiltration without clogging, while microfiltration membranes are for fine particle retention.

Versus Sintered metal filters

Mesh filters are lower cost and easier to dispose of, while sintered metal filters offer higher durability but are not suitable for all solvents.

Versus Paper filters

Mesh filters are reusable in concept and more chemically resistant, while paper filters are single-use and degrade in aggressive solvents.

Versus Standard nylon mesh from other suppliers

Microlab's mesh has precise weaving with consistent open area and thickness, reducing variability between batches.

Use Guide

How To Use It

Select nylon for applications requiring higher tensile strength and moderate chemical resistance
Choose polypropylene for maximum chemical compatibility with aggressive solvents
Use 100-180 µm mesh for removing large particulates or debris from bulk liquids
Use 30-80 µm mesh for prefiltration of solvents before injection into analytical instruments
Ensure the filter is properly seated in the filtration holder to avoid bypass flow
Discard after use to prevent carry-over; do not reuse in critical applications

FAQ

Questions Buyers Ask

What is the difference between nylon and polypropylene mesh filters?

Nylon offers higher tensile strength and is suitable for moderate chemical environments. Polypropylene is 100% virgin and provides broader chemical compatibility, especially with aggressive solvents.

Which mesh size should I use for solvent prefiltration?

For solvent prefiltration, use 100 µm or 120 µm mesh to remove coarse particulates without clogging. For more demanding applications, 80 µm or 60 µm may be used.

Can these filters be used with aggressive solvents?

Yes. Both nylon and polypropylene mesh filters are designed for broad chemical compatibility, including with aggressive solvents.

Are the filters reusable?

No. These are single-use filters designed for one-time use to prevent carry-over and ensure consistent performance.

What is the packing quantity?

Each pack contains 100 pieces. The filters are supplied in bulk with no individual packaging.

Can I get these under my own brand?

Yes. The Microlab OEM division offers private-label printing and packing, as well as OEM contract manufacturing for custom mesh configurations.
