Whatman 1827-047 Glass Microfiber Binder-Free Filter 1.5µm 47mm

Description

Product Overview

The Whatman 1827-047 glass microfiber binder free filter is engineered for demanding laboratory environments where precision and reliability are paramount. Featuring a uniform 1.5 micron pore size, the filter captures suspended particles while maintaining a high flow rate of 3.7 S per 100 mL, allowing rapid processing of large sample volumes. The filter media is composed of high‑purity glass fibers that are chemically inert, providing excellent resistance to a wide range of solvents and reagents. Its 47 mm diameter format fits standard laboratory filtration apparatus, and the binder‑free construction eliminates the risk of leaching, ensuring that downstream analytical results remain uncontaminated.

Manufactured in the United States under strict quality‑control protocols, each filter meets the requirements of ASTM standard 2540D for total suspended solids (TSS) determination. The product is packaged in a compact box measuring 4.69 × 2.48 × 1.14 inches and weighs only 0.32 ounces, facilitating easy storage and handling in busy lab settings. The model number 1827-047 is clearly printed on the packaging for quick identification, and the filter is listed under ASIN B071DJKT5L for convenient online ordering.

Usage

This filter excels in a variety of laboratory applications. It is routinely used for water pollution monitoring, where its fine pore size effectively removes turbidity and suspended solids, enabling accurate downstream chemical analysis. In microbiology labs, the filter supports bacterial culture harvesting by retaining cells while allowing clear filtrate to pass, which is essential for downstream assays such as liquid scintillation counting. The binder‑free design also makes it suitable for air pollution monitoring setups that require filtration of aerosolized particles without introducing additional contaminants.

Because the filter tolerates a broad temperature range, it can be employed in both ambient and refrigerated conditions, making it adaptable to protocols that involve temperature‑sensitive reagents. Its compatibility with standard laboratory filtration equipment, including vacuum manifolds and syringe filters, ensures seamless integration into existing workflows. Users appreciate the consistent performance across multiple batches, which reduces variability in experimental results and enhances reproducibility.
