Demanding filtration tasks involving high particle loads or extreme temperatures require the superior structural integrity of glass media. LabFriend offers a comprehensive selection of glass fiber filters, located within the filtration section of our distillation, separation, and filtration department. These professional microfibre discs are engineered for fast flow rates and exceptional loading capacity in analytical and environmental testing.
Why Choose Professional Glass Fiber Filters?
Our curated collection of microfibre media is designed for thermal stability, chemical inertness, and fine particle retention:
- High-Retention Microfibre Discs: We stock Sartorius Glass Microfibre Discs (MGC and MGF) in various diameters (25 mm to 110 mm), providing reliable depth filtration for liquid clarification.
- Pure Binder-Free Options: Utilize Hahnemühle Glass Microfibre Filters (GF50, GF52) and LLG 90mm Filters, which are binder-free to prevent sample contamination and ensure maximum chemical resistance.
- Inorganic Binder Performance: Explore Hahnemühle GF9 Filters, featuring inorganic binders for enhanced mechanical strength in specific specialized applications.
- Exceptional Loading Capacity: Glass fiber media, such as the Sartorius MG 227/1/60, offer significantly higher particle loading capabilities than standard cellulose papers, extending filter life.
LabFriend supplies glass fiber filters from the world's most innovative manufacturers in separation science:
- Sartorius: A global leader in filtration technology, providing a wide range of MGC, MGF, and MG series microfibre discs for critical analytical tasks.
- Hahnemühle: Renowned for high-purity technical papers, offering a comprehensive array of binder-free glass filters like the GF52 and GF50 series.
- LLG Labware: Provides high-quality, cost-effective binder-free microfibre filters for routine laboratory use and environmental monitoring.
Superior filter media ensure the accuracy of downstream analysis; to further complete your filtration or synthesis assembly, we recommend exploring these related categories:
- Filtration Apparatus: Use your microfibre discs with specialized LLG-filter holders or DWK Duran slit sieve plates for vacuum-assisted separation.
- Quantitative Filter Paper: For gravimetric analysis where ashing is required, utilize LLG ashless cellulose circles.
- In-Line Filters: Protect sensitive vacuum pumps during large-scale glass fiber filtration using Sartorius air filtration units.
- Distillation Accessories: Ensure steady boiling in subsequent concentration steps using J.P. Pöllath boiling stones.
Unsure if a binder-free GF52 or an inorganic-bound GF9 filter is best for your high-temperature air sampling? Our team provides local technical support to help you find the perfect filtration solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What are the main advantages of glass fiber filters over cellulose?
Glass fiber filters offer much faster flow rates, higher particle loading capacity, and greater thermal resistance (up to 500°C for binder-free versions) compared to standard cellulose papers.
2. What does "binder-free" mean?
Binder-free filters, like the Hahnemühle GF52 or LLG 90mm microfibre discs, do not contain chemical glues. This ensures maximum purity and prevents any binders from leaching into your sample during filtration.
3. When should I use a filter with an inorganic binder?
Filters with inorganic binders, such as the Hahnemühle GF9, are chosen when extra mechanical strength is needed for handling or when the specific binder does not interfere with the intended analysis.
4. Are these filters suitable for environmental monitoring?
Yes, glass fiber filters are the standard choice for suspended solids testing in water and for air pollution monitoring due to their high efficiency and stability.
