StonyLab Qualitative Filter Paper Circles, 74mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100

Buchner funnels are indispensable tools in chemistry laboratories, widely employed for vacuum filtration. One crucial component that enhances their efficiency is the paper filter. These filters play a pivotal role in the separation of solids from liquids, offering a range of benefits that significantly contribute to the success of various scientific experiments.Enhanced Filtration EfficiencyOne of the primary advantages of utilizing paper filters in Buchner funnels is the notable improvement in filtration efficiency. The porous structure of paper filters allows for the efficient retention of solid particles while facilitating the passage of liquid through the filter. This ensures a faster and more effective separation process, saving valuable time in the laboratory.Precise Particle RetentionPaper filters exhibit a remarkable ability to retain particles of different sizes with precision. This is particularly important in experiments where the separation of specific particle sizes is critical. The controlled porosity of paper filters enables scientists to tailor their filtration processes according to the requirements of their experiments, ensuring accurate and reliable results.Reduced Risk of ContaminationThe use of paper filters in Buchner funnels helps minimize the risk of contamination in experimental samples. The high-quality materials used in manufacturing these filters, such as cellulose or glass microfiber, provide a clean and inert environment for the filtration process. This is especially crucial in sensitive experiments where even trace contaminants can skew results.Compatibility with a Variety of SubstancesPaper filters are versatile and compatible with a wide range of substances, making them suitable for diverse laboratory applications. Whether filtering aqueous solutions, organic solvents, or suspensions, paper filters exhibit stability and effectiveness across different chemical environments. This versatility makes them a go-to choice for scientists working with various substances in their research.Ease of Use and ConvenienceThe simplicity of incorporating paper filters into Buchner funnels adds to their appeal. The filters are readily available, easy to handle, and require minimal preparation. This convenience not only streamlines laboratory procedures but also enhances the overall user experience. Researchers can focus on the scientific aspects of their work without being burdened by complicated filtration processes.Cost-EffectivenessFrom an economic standpoint, paper filters offer a cost-effective solution for laboratory filtration. Compared to some alternative filtration methods, the affordability of paper filters makes them an attractive choice for researchers working within budget constraints. This cost-effectiveness does not compromise the quality of results, making paper filters a practical and efficient option for a wide range of scientific applications.ConclusionIn conclusion, the integration of paper filters into Buchner funnels brings about a myriad of benefits that significantly contribute to the success of laboratory experiments. From enhanced filtration efficiency and precise particle retention to reduced contamination risks and versatility across different substances, paper filters prove to be indispensable tools in the scientific toolkit. Their ease of use, cost-effectiveness, and overall convenience further underscore their importance in facilitating successful and reliable filtration processes in the realm of laboratory research.

These 56mm filters fit perfectly in a CoorsTek 60240 porcelain buchner funnel.I could not get them to fit with Stonylab porcelain buchner filters.They work best with cold water extractions, from my experience, but i have used water alcohol mixtures, solvents such as chloroform, and vacuum filtration of small amounts of concentrated acids, and they seem to hold up well.They work well for filtering fine charcoal, and other fine particulates.I use them almost daily!

Used for filtering dirty solvent form cleaning 3D prints.

Perfect fit for a 10cm buchner funnel

It's good filter paper, performs exactly as expected.

Prompt delivery, works well, no issues after a few times of use. Good purchase.

Seems to be hard to find this size at good price - received in good order.

All of the filters were good

very good quality and durability. It can withstand even most alkali or oxine compounds

Saves me a ton of time and hassle having to cut filters for my Closed Loop extractor. The 75mm is perfect for tri clamp sanitary 3” spools to fit in the gasket without overlapping the Center ring of the gasket, allowing the filter to be clamped in the gasket so it doesn’t move during extraction or have product pass by without being filtered.All in all a great purchase, high quality, low box design to save you a few extra dollars. Even the company name fits in with BHO extraction almost haha Stony lab! Keep up the great work!If you do BHO as well then this is the stuff to get, the quantitive contains Ash and it will contaminate the product return.

Conforme et très bien Utilisé pour filtrer des solution acides.

Todo correcto

It’s a filter and it’s made of paper
