Description
The Thermo Scientific 723-9945 Syringe Filter is a laboratory consumable designed for the filtration of small to moderate volumes of liquids. This filter has a 25 mm diameter and utilizes a SFCA (Surfactant-Free Cellulose Acetate) membrane with a 0.45 µm pore size.
The SFCA membrane is a key feature, as it is a low-protein-binding material that provides high flow rates, making it ideal for filtering sensitive biological samples like cell culture media and protein solutions. The 0.45 µm pore size is a common choice for clarification, effectively removing particulates and microorganisms while allowing the passage of the target molecules. The 25 mm diameter of the filter housing provides a sufficient filtration area for processing volumes up to a few hundred milliliters.
These syringe filters are designed to be attached to a syringe, allowing for manual filtration of liquids as they are pushed through the filter. They are an essential tool for sample preparation for chromatography (e.g., HPLC), sterilization of small volumes of solutions, and general laboratory clarification.
