Product type
Filter paper is a porous paper used to separate solids from liquids or gases in various industrial and laboratory applications. It is typically made from cellulose fibers that are processed to create a uniform thickness and porosity, allowing for efficient filtration. The paper can be treated with various chemicals to enhance its performance depending on the specific application requirements.
| Material | Cellulose fibers |
| Typical thickness | 50 to 500 microns |
| Filtration speed | Varies by grade, typically measured in seconds per 100 mL |
| pH range | 4 to 8 |
| Standard sizes | Various diameters from 25 mm to 500 mm |
| Grammage | 40 to 300 g/m² |
When selecting filter paper, consider the specific application and the required filtration efficiency. Factors such as thickness, porosity, and chemical compatibility are crucial. Specify the desired grade, tolerances, and any necessary certifications, such as compliance with FDA or ISO standards. It's also important to indicate the quantity needed to ensure accurate pricing and availability.
