The pore size ofdrug filtration membrane refers to the diameter of its micropore structure, which is an important parameter to measure the filtration performance of the filtration membrane. Its pore size is usually between 0.1 and 10 microns, and different pore sizes can be selected for application according to needs.
The pore size of the drug filter membrane is critical for drug preparation and production has an important impact. Generally speaking, filter membranes with smaller pore sizes can remove microscopic impurities such as small particles, tiny bacteria, and viruses, thereby improving the purity and stability of drugs; while larger pore sizes can retain some active ingredients with larger molecular weights. , such as protein, etc., to ensure the biological activity and effect of the product.
When selecting the pore size, it is necessary to consider the characteristics and process conditions of the drug, as well as the size of the impurities to be removed and the target component. For example, in the production process of injections, it is necessary to use drug filter membrane with a pore size below 0.2 micron for filtration and purification to remove small bacteria and microorganisms; while in the preparation process of oral tablets, the pore size Usually between 0.45 and 1 micron to ensure that the active ingredients in the preparation are retained.
In addition to pore size, pore size distribution is also an important parameter. The more uniform the pore size distribution, the more stable the filtration performance. Some good ones can control their pore size distribution pattern and range, thereby improving separation efficiency and stability.
The pore size of the medicinal liquid filtration membrane is an important parameter to measure its filtration performance. Membranes with different pore sizes have different applicability and application prospects in pharmaceutical preparation and production processes. Choosing the appropriate pore size can improve the purity and stability of the drug, thereby ensuring the quality of the drug. Interested parties can enter the store and contact us.
