Polyacrylonitrile (PAN) FAQ

Polyacrylonitrile (PAN) membrane filters combine excellent selectivity, high flow rates, and low operating pressure, making them ideal for efficient microfiltration and ultrafiltration applications. Their high permeability enables fast filtration while maintaining reliable separation performance, helping reduce energy consumption and improve process efficiency. PAN membranes are widely used in water treatment, biotechnology, food and beverage processing, and other laboratory and industrial filtration applications.

Yes. Polyacrylonitrile (PAN) membrane filters are absolute-rated at 0.2 µm and provide bacterial retention with a typical 6-log reduction value (LRV). This level of performance can meet EPA drinking water standards for microorganism removal, provided the filtration system is properly designed. For critical applications, the integrity of both the membrane filter and the filter holder assembly must be verified to ensure effective sealing and reliable filtration performance.

No. Polyacrylonitrile (PAN) membrane filters are not compatible with autoclave sterilization. For sanitization, they may be treated with 90 °C hot water for 30 minutes or soaked in ethanol, depending on your application and compatibility requirements.
