Ahlstrom 9610-1850 Wet Qualitative Filter Paper 18.5cm 40micron

Description

Product Overview

The Ahlstrom 9610-1850 wet‑strengthened qualitative filter paper is engineered for precise laboratory filtration tasks. Constructed from high‑purity cellulose fibers, the paper provides a uniform pore structure of 40 microns, enabling consistent flow rates and reliable capture of particulate matter during qualitative analysis. Each sheet measures 18.5 cm in diameter and weighs approximately 10 ounces, offering a convenient size for standard filter holders while maintaining sufficient surface area for bulk sample processing.

Key manufacturing specifications include a low ash content of 0.06%, which minimizes background interference and enhances the clarity of analytical results. The untreated nature of the paper preserves its natural absorbency, while the wet‑strengthened treatment ensures that the filter retains structural integrity even when exposed to high moisture levels or aggressive solvents. This combination of low ash, untreated composition, and wet‑strengthening makes the product especially suitable for a wide range of qualitative laboratory procedures, from precipitation tests to thin‑layer chromatography.

Since its introduction in May 2019, the 9610-1850 model has achieved a strong market presence, ranking #49 in the Qualitative Lab Filter Paper category on major e‑commerce platforms. The product is supplied by Ahlstrom, a globally recognized manufacturer known for its rigorous quality control processes and commitment to sustainable production practices.

Usage

This filter paper is designed for use in academic, industrial, and research laboratory environments where reliable qualitative filtration is essential. It performs optimally in applications such as gravimetric analysis, precipitation reactions, and the filtration of reaction mixtures prior to spectroscopic or chromatographic evaluation. The wet‑strengthened feature allows the paper to withstand prolonged exposure to aqueous solutions without tearing, making it ideal for procedures that involve repeated washing or prolonged contact with liquids.

Laboratory technicians, chemists, and quality‑control personnel will find the 18.5 cm diameter compatible with most standard filter funnels and vacuum filtration setups. The bulk packaging format reduces per‑unit cost and ensures a steady supply for high‑throughput laboratories, while the consistent performance across batches supports reproducibility in experimental protocols.

In addition to traditional wet chemistry workflows, the filter paper can be employed in environmental testing labs for the collection of particulate samples from water sources, as well as in educational settings where students conduct qualitative experiments that require dependable filtration media.

Why Choose Us

Choosing the Ahlstrom 9610-1850 filter paper means selecting a product backed by decades of expertise in fiber technology and filtration media. Ahlstrom’s manufacturing facilities adhere to ISO‑9001 and ISO‑14001 standards, guaranteeing that each batch meets stringent quality and environmental criteria. The low ash content and untreated composition reduce the risk of contaminant introduction, a critical factor for sensitive analytical methods.

FAQ

What makes wet‑strengthened filter paper different from regular filter paper?

Wet‑strengthened filter paper undergoes a treatment that reinforces the cellulose fibers, allowing the paper to retain its shape and strength when saturated with liquids. This prevents tearing or collapse during prolonged filtration, which is a common issue with untreated papers in high‑moisture applications.

Can this filter paper be used for both aqueous and organic solvents?

Yes. The untreated cellulose base provides good compatibility with a wide range of solvents, while the wet‑strengthened coating ensures durability in both aqueous and certain organic environments. However, for highly aggressive solvents, it is recommended to verify chemical compatibility with the specific solvent system.

How does the low ash content benefit my analytical results?

Low ash content means fewer inorganic residues remain on the filter after use, reducing the potential for background signals or contamination in downstream analytical techniques such as spectroscopy or chromatography. This contributes to clearer, more accurate qualitative data.

Is the 18.5 cm diameter compatible with standard laboratory equipment?

The 18.5 cm (approximately 7.3 in) diameter is a common size for laboratory filter funnels and vacuum filtration setups. It fits most standard holders, allowing seamless integration without the need for specialized adapters.

What support is available if I encounter issues with the product?
