Whatman 10312209 Quantitative Filter Paper 90mm 8 to 10 Micron Grade

Description

Product Overview

The Whatman 10312209 Quantitative Filter Paper is engineered for precision laboratory work where consistency, speed, and capacity are paramount. Each sheet measures 90mm in diameter and is fabricated from high‑quality cellulose fibers that provide a uniform pore structure, ensuring reliable retention of particles in the 8 to 10 micron range. The paper’s typical thickness of 320µm and basis weight of 140g/m² contribute to its robustness, allowing it to withstand high loading without tearing or deformation. Designed with a thick pleated configuration, the filter paper maximizes surface area, facilitating rapid fluid flow while maintaining the desired retention characteristics. This balance of medium retention and medium‑fast to quick filtration speed makes it suitable for a broad spectrum of quantitative analytical procedures, including gravimetric analysis, precipitation, and sample clarification. The product is supplied in a convenient pack of 100 sheets, each individually sized for easy handling and consistent performance across multiple experiments. Manufactured by GE Healthcare Life Sciences, the filter paper adheres to stringent quality standards, reflected in its high customer rating of 4.7 out of 5 stars based on ten reviews. Its best‑seller rank within the Quantitative Lab Filter Paper category underscores its popularity among researchers seeking dependable filtration solutions.
