Product Overview

The Whatman RC58 Membrane Filter is engineered for high-performance filtration in laboratory settings, offering exceptional chemical compatibility and mechanical strength. Constructed from regenerated cellulose, this filter provides a 0.2?m pore size, ensuring the removal of fine particulates, bacteria, and other contaminants with precision. Its hydrophilic nature allows for rapid wetting and consistent flow rates, making it ideal for applications requiring high throughput and reliability. The RC58 membrane is resistant to a wide range of solvents, acids, and bases, ensuring stability across diverse experimental conditions. Its low extractables profile minimizes interference with sensitive analyses, while the smooth surface reduces particle retention, enhancing filtration efficiency. Available in multiple diameters, this filter is compatible with standard filtration apparatus, providing versatility for various lab setups. Whether used for sterilization, clarification, or sample preparation, the Whatman RC58 delivers consistent results, backed by rigorous quality control standards to meet the demands of modern research and industrial laboratories.

FAQs

1. What is the chemical resistance of the Whatman RC58 membrane filter?

This filter is compatible with a broad range of solvents, including alcohols, ketones, and mild acids/bases, but avoid strong oxidizing agents.

2. Can this filter be autoclaved for sterilization?

Yes, the Whatman RC58 membrane can be autoclaved at 121?C for 20 minutes without compromising integrity.

3. How does the flow rate compare to other 0.2?m filters?

The hydrophilic regenerated cellulose material ensures faster flow rates compared to hydrophobic membranes like PTFE.

4. Is this filter suitable for protein-binding studies?

The RC58 membrane has low protein-binding properties, making it suitable for biological sample filtration.

5. What is the shelf life of these filters when stored properly?

When stored in a cool, dry environment, the filters retain performance for up to 3 years from the date of manufacture.
