EISCO Economy Filter Papers 100PK 12.5cm 8-10µm Qualitative

Description

Product Overview

The EISCO 100PK Economy Filter Papers are engineered to meet the demanding needs of both educational laboratories and everyday users who require consistent, high‑quality filtration. Each sheet measures a precise 12.5 cm in diameter, providing a standard size that fits most laboratory funnels, Buchner plates, and coffee makers. The paper is manufactured with a uniform pore size ranging from 8 to 10 microns, delivering reliable retention of particulate matter while allowing liquids to pass through efficiently. This balance of filtration strength and flow rate makes the papers suitable for a wide range of qualitative analytical techniques, including thin‑layer chromatography, gravimetric analysis, and simple distillation experiments. The material composition is a high‑purity cellulose blend that resists tearing, ensuring clean, intact sheets even under the pressure of vacuum filtration. With a pack of 100 sheets, users benefit from a generous supply that supports repeated testing, classroom demonstrations, and bulk laboratory work without the need for frequent reordering.

Usage

These filter papers excel in environments where clarity of results and ease of handling are paramount. In academic settings, chemistry instructors rely on the consistent pore structure to teach students the fundamentals of separation techniques, allowing learners to observe clear visual differences between filtrates and residues. In research laboratories, the papers are employed for sample preparation, where they help isolate solid phases from liquids before further analysis by spectroscopic or chromatographic methods. Beyond the lab, the same sheets are popular among coffee enthusiasts who appreciate the ability to brew a smooth cup without the bitterness that can arise from over‑extraction. The durability of the cellulose matrix also makes the papers suitable for field work, where portable filtration setups are required for water quality testing or environmental sampling. Users can simply place a sheet in a funnel, pour the sample, and collect the filtrate, confident that the paper will not fragment or introduce contaminants.

FAQ

What types of experiments are these filter papers best suited for?

They are ideal for qualitative analytical techniques such as thin‑layer chromatography, gravimetric analysis, simple distillation, and any procedure that requires a clean, uniform filtration medium.

Can I use these papers for coffee brewing at home?

Yes, the 12.5 cm size fits standard coffee makers, and the 8‑10 micron pores allow for a smooth brew while retaining coffee grounds, making them a convenient option for home baristas.

How should I store the filter papers to maintain their performance?

Keep the unopened package in a cool, dry place away from direct sunlight. Once opened, reseal the container or transfer the sheets to an airtight bag to protect them from moisture.

Do the filter papers contain any additives or chemicals that could affect my samples?

No, they are made from high‑purity cellulose without additives, ensuring that they do not introduce contaminants into your filtrates.

What is the difference between these economy papers and premium laboratory filter papers?

The economy version offers excellent performance for most qualitative applications at a lower cost, while premium papers may provide finer pore control or specialized coatings for highly sensitive analytical methods.
