Laboratory depth filtration and monitoring
High-loading laboratory depth media for prefiltration, clarification, gravimetric analysis, aerosol collection and high-temperature monitoring.
Grade-specific retention, background contribution and temperature suitability must be confirmed for the analytical method
Basic information
Glass and quartz microfiber filters form a random, tortuous fiber network that captures particles on the surface and throughout the media depth. This structure supports fast flow and high particulate loading, making the media useful as a direct analytical filter or as protection for a downstream membrane.
Borosilicate glass media for high-loading prefiltration, clarification, gravimetric analysis and particulate collection.
Construction options Binder / Binder-free
High-purity microfiber media for demanding temperature, chemical resistance and low-background monitoring requirements.
Primary selection duty High-temperature monitoring
Media, format and method selection
Borosilicate glass media with binder provide additional handling strength. Binder-free glass prioritizes purity and gravimetric stability. Quartz microfiber is selected where high temperature, chemical resistance or low trace-element background is important. Grade, format and retention must be matched to the analytical method.
End-user applications
Select glass or quartz, binder condition, grade and format around the sample matrix, analytical endpoint and installed equipment.
Prefiltration of particle-laden liquids before membrane filtration.
Clarification of buffers, reagents and analytical samples.
Total suspended solids and gravimetric residue determination.
Collection of airborne particulate matter and aerosols.
Stack, combustion and high-temperature emission monitoring.
Trace-element work requiring controlled filter background.
Quotation preparation
A complete RFQ should identify the sample matrix, analytical duty, grade-specific performance, installed equipment and documentation requirements for technical review.
Identify the analytical method, liquid or gas matrix, solids load and expected volume.
Confirm glass or quartz, binder condition, purity and required mechanical strength.
Provide grade-specific retention, penetration, flow, pressure-drop or loading targets.
State disc diameter, sheet dimensions, roll width and length, or custom die-cut geometry.
Define temperature, chemistry, humidity, preheating and certificate requirements.
Configuration matrix
Configuration note. Glass and quartz microfiber filters are depth media, not absolute-pore membranes. Retention, blank contribution, temperature suitability and sterilizing performance must not be inferred from a nominal micron value.
| Customizable format | Media | Pore size / retention |
|---|---|---|
| Disc Filter | Borosilicate glass fiber with binder | Nominal or grade-specific retention: 0.2 / 0.45 / 0.8 / 1.0 / 2.0 / 3.0 / 5.0 / 10.0 µm |
| Sheets | Pure borosilicate glass fiber with no binder | Grade-specific particle retention; confirm method and loading profile |
| Roll Tape | Quartz fiber | Grade-specific aerosol retention / penetration; confirm sampler and method |
Confirm the analytical method, sample matrix, glass or quartz media, binder condition, grade, format, operating conditions and documentation requirements before submitting the final RFQ.
