Description
Product Overview
The Whatman 1825-047 glass microfiber filter is engineered to provide a reliable 0.7 µm particle retention capability within a 4.7 cm diameter GF/F disc format. Constructed from high‑purity glass fibers, the filter offers a uniform pore structure that enables consistent performance across a wide range of laboratory applications. Its binder‑free composition eliminates the risk of sample contamination, making it especially suitable for sensitive molecular biology protocols such as DNA purification and protein precipitation.
Manufactured by Whatman, a globally recognized leader in filtration technology, this filter benefits from rigorous quality control processes that ensure each disc meets exacting standards for thickness, pore size distribution, and mechanical strength. The disc’s 19 seconds per 100 mL flow rate provides a balance between rapid processing and high retention efficiency, allowing researchers to achieve fast turnaround times without compromising on filtration quality.
Key specifications include a 0.7 µm retention rating, a 4.7 cm (47 mm) diameter GF/F grade, and a flow rate of 19 seconds per 100 mL. The product is supplied in a pack of 100 discs, offering a cost‑effective solution for laboratories that require large volumes of filtered samples on a regular basis. Its compatibility with standard laboratory filtration apparatus further simplifies integration into existing workflows.
Usage
This filter excels in a variety of laboratory settings, from molecular genetics to biochemistry. Researchers performing DNA binding assays will appreciate the filter’s ability to retain nucleic acids while allowing small molecules and salts to pass through, thereby enhancing downstream purification steps. In protein chemistry, the filter efficiently removes finely precipitated proteins, reducing background noise and improving the clarity of subsequent analyses such as SDS‑PAGE or mass spectrometry.
The disc format is compatible with common filtration devices, including vacuum manifolds, syringe filters, and centrifuge‑based systems. Its binder‑free nature ensures that no leachable substances interfere with sensitive assays, making it a reliable choice for applications that demand high purity and reproducibility. The filter’s robust construction also tolerates repeated handling, allowing technicians to load and unload discs with minimal risk of breakage.
