The porosity ofdrug filter membrane refers to the proportion of the pore space in the filter membrane to the total volume. It is one of the important parameters to measure the filtration performance and water permeability of Medicinal Liquid Filtration Membrane. The porosity is usually between 20% and 80%, and different porosity can be selected according to different application requirements.
Porosity has an important impact on pharmaceutical preparation and production. Generally speaking, a drug filtration membrane with a higher porosity can achieve fast flow rate and high water permeability, improving production efficiency; while a lower porosity can remove smaller particles and bacteria. Remove microscopic impurities such as bodies and viruses, thereby improving the purity and stability of drugs.
When selecting porosity, the characteristics of the drug and process conditions need to be taken into consideration. For example, in the production process of injections, it is necessary to use materials with higher porosity (70%~80%) for filtration and purification to ensure sufficient flow rate and water permeability; in the field of biotechnology, it is often necessary to use materials with higher porosity (70%~80%). Low (20%~40%) for fine filtration and removal of microscopic impurities.
In addition to porosity size, pore morphology is also an important parameter. Different shapes of holes have different filtering effects and water permeability. For example, spherical holes can achieve larger channel area and flow rate, but are also prone to perforation and rupture; while cylindrical holes can ensure better mechanical strength and stability.
In short, the porosity of drug filtration membrane is an important parameter to measure its filtration performance and water permeability. Choosing the appropriate porosity and pore morphology can improve the purity and stability of pharmaceutical products and reduce formulation costs and production time. Reasonable selection and configuration based on drug characteristics and process conditions can meet the needs of different drug preparation and production, providing a wide range of application prospects for the pharmaceutical industry.
