Description
Product Overview
The Ahlstrom 6170-1100 qualitative filter paper is engineered for high‑performance laboratory and industrial filtration tasks. Constructed from more than 95% super‑refined alpha‑cellulose and linter fibers, this filter paper offers exceptional purity, uniform pore structure, and a robust loading capacity that can handle coarse particles, gelatinous precipitates, and viscous solutions. Each sheet measures 11 cm in diameter with a nominal thickness of 35 µm, delivering a fast‑flow rate that reduces filtration time while preserving the integrity of the sample. The grade 617 designation indicates a thicker, higher‑capacity media suitable for rapid removal of larger particulates, making it an ideal choice for applications involving oils, resin solutions, and other challenging matrices. Packaged in a convenient set of 50 sheets, the product ensures consistent performance across multiple experiments and processes, reducing variability and supporting reproducible results.

Usage
This qualitative filter paper excels in a variety of settings where reliable separation is essential. In academic and research laboratories, it is commonly used for routine gravimetric analysis, precipitation filtration, and sample preparation prior to chromatography or spectroscopy. Its fast‑flow characteristics enable quick processing of large sample volumes, which is particularly valuable in quality‑control environments where throughput is critical. Industrial users benefit from the paper’s ability to handle viscous or oil‑laden suspensions, making it suitable for pre‑filtration steps in chemical manufacturing, petrochemical processing, and polymer synthesis. The filter paper’s compatibility with standard quadrant‑folded filter holders and gravity‑flow apparatus ensures seamless integration into existing workflows, while its high loading capacity minimizes the need for frequent filter changes, thereby improving operational efficiency and reducing waste.

FAQ
What types of samples are best filtered with this paper?
This filter paper is ideal for coarse particles, oil‑based suspensions, resin solutions, and gelatinous precipitates where rapid flow and high loading capacity are required.
Can the filter paper be used with standard quadrant‑folded holders?
Yes, the 11 cm diameter is compatible with most standard quadrant‑folded filter holders and gravity‑flow apparatus commonly found in laboratories.
How does the fast‑flow design affect filtration efficiency?
The fast‑flow design minimizes resistance, allowing quicker passage of liquids while still retaining particles above the 35 µm rating, which improves overall throughput without sacrificing filtration quality.
Is the filter paper suitable for high‑temperature applications?
While the paper performs well at typical laboratory temperatures, it is not recommended for use above 120 °C as the cellulose fibers may degrade.
What support does Ahlstrom provide for troubleshooting?
Ahlstrom offers technical assistance through email and phone, detailed product datasheets, and application notes to help users optimize filtration protocols and resolve any performance issues.
