Description

Product Overview

The CA Membrane Filter with an outer diameter of 47mm is engineered to meet the rigorous demands of modern laboratory and industrial filtration. Featuring a precise 0.22 um pore size, this filter reliably captures microscopic particles, bacteria, and contaminants, ensuring the purity of liquids and gases in a wide range of applications. Constructed from high‑grade cellulose acetate, the membrane provides excellent chemical resistance, low protein binding, and consistent flow rates, making it a trusted choice for analytical chemistry, microbiology, environmental testing, and quality control processes. Each lot contains 50 sheets, each sheet measuring 47mm in diameter, allowing users to maintain a steady inventory for routine assays, method development, and validation studies. The filter’s robust design tolerates standard autoclaving and chemical cleaning procedures, extending its service life and reducing overall consumable costs. Compatibility with standard filter holders and vacuum manifolds ensures seamless integration into existing workflows, while the clear labeling on each sheet simplifies identification and reduces the risk of cross‑contamination. This product is manufactured by Deschem, a reputable supplier known for delivering reliable filtration solutions to scientific and industrial markets worldwide.

Usage

Designed for versatility, the 47mm CA membrane filter excels in a variety of realistic usage environments. In microbiology labs, it is employed to filter culture media, sterilize solutions, and isolate microorganisms for downstream analysis. Analytical chemists rely on its low protein binding properties to filter samples prior to chromatography, spectroscopy, or mass spectrometry, preserving sample integrity and preventing column fouling. Environmental testing professionals use the filter to remove particulate matter from water, air, and soil extracts, enabling accurate detection of contaminants such as heavy metals, pesticides, and organic compounds. The filter’s chemical resistance allows it to handle acidic, basic, and organic solvents commonly encountered in industrial processes, including pharmaceutical manufacturing, food and beverage quality assurance, and petrochemical analysis. Its 0.22 um pore size meets the standard requirement for sterilizing-grade filtration, making it suitable for preparing sterile solutions, vaccines, and biologics. The 50‑sheet packaging supports high‑throughput laboratories, providing a convenient stock that minimizes downtime and ensures consistent performance across multiple experiments. Users can employ the filter with vacuum filtration setups, positive pressure systems, or syringe filtration, adapting to the specific needs of each protocol.

FAQ

What types of samples can I filter with this membrane?

The CA membrane filter is suitable for a broad range of aqueous and organic samples, including culture media, buffer solutions, environmental water extracts, and solvents used in analytical chemistry. Its chemical resistance allows filtration of acidic, basic, and organic solutions, while the 0.22 µm pore size ensures removal of bacteria, spores, and fine particulates.

Can the filter be autoclaved for reuse?

Yes, the cellulose acetate membrane can withstand standard autoclave cycles (121 °C, 15 psi) without compromising its structural integrity or pore size. After autoclaving, the filter should be allowed to cool and dry before reuse to maintain optimal performance.

Is this filter compatible with vacuum and positive‑pressure filtration systems?

Absolutely. The 47 mm diameter is designed to fit standard vacuum filtration manifolds, positive‑pressure filter holders, and syringe filter adapters. This flexibility enables users to select the most appropriate filtration method for their specific protocol.

How does the filter perform with protein‑rich samples?

Cellulose acetate exhibits low protein binding, making the filter ideal for applications where protein recovery is critical. It minimizes adsorption of proteins onto the membrane surface, preserving sample concentration and activity for downstream assays such as ELISA, Western blotting, or chromatography.

What warranty or support does Deschem provide?

Deschem offers a limited warranty covering manufacturing defects and provides technical support for product selection, protocol optimization, and troubleshooting. Customers can contact our support team via email or phone for prompt assistance, and replacement units are provided for any batch that fails to meet performance specifications.
