Hahnemühle is one of the world’s oldest and most respected paper manufacturers, with a history of excellence dating back to 1584. Based in Dassel, Germany, the company has evolved from a traditional paper mill into a global leader in high-purity filtration media for laboratory and industrial applications. Hahnemühle’s mission is centered on "Purity and Precision," utilizing pristine spring water and high-quality alpha-cellulose to produce papers that are virtually free of impurities. Their laboratory division is renowned for setting the benchmark in consistency, ensuring that researchers can rely on identical filtration characteristics from batch to batch. By combining centuries of papermaking tradition with modern cleanroom production technology, Hahnemühle remains the primary choice for scientists who demand the highest levels of chemical resistance and particle retention in their analytical workflows.
The Hahnemühle range at LabFriend features professional filtration and separation solutions, headlined by an extensive selection of qualitative and quantitative ashless filter papers. These are essential for gravimetric analysis and general clarification in chemistry and environmental labs. For air and water monitoring, the brand provides advanced environmental analysis tools, including high-performance glass fiber filters and extraction thimbles for Soxhlet systems. Their portfolio also includes specialized life science media, such as blotting papers for Western, Southern, and Northern blots, and chromatography papers for separation science. To support industrial quality control, Hahnemühle offers specialized papers for the food, beverage, and sugar industries. By choosing Hahnemühle through LabFriend, you benefit from competitive pricing and fast shipping on German-engineered filtration products designed for scientific integrity.

Frequently Asked Questions
1. What is the difference between qualitative and quantitative filter paper?
Qualitative paper is used for identifying materials and general clarification. Quantitative (ashless) paper is acid-washed to achieve an extremely low ash content (typically <0.01%), making it ideal for gravimetric analysis where the filter is burned off.
2. Can Hahnemühle glass fiber filters be used for high-temperature filtration?
Yes, glass fiber filters are highly temperature-resistant and can typically withstand temperatures up to 500°C, making them suitable for air monitoring and volatile suspended solids testing.
3. How do I select the right filter speed for my application?
"Fast" filters have larger pores and are best for coarse precipitates, while "Slow" filters have a tighter fiber matrix designed to catch very fine particles but will result in a longer filtration time.
4. Are Hahnemühle extraction thimbles compatible with all Soxhlet extractors?
Hahnemühle produces thimbles in all standard international sizes. It is important to match the outer diameter and length of the thimble to the internal dimensions of your specific Soxhlet extraction tube.
