Test screening, also known as standard test screening, sample screening, analysis screening, etc., is widely used in the pharmaceutical industry. It is mainly used for the accurate screening, filtering and detection of granular and powdery drug size structure, liquid content and impurities.

How can test screening be used in screening and testing in pharmaceutical industry?

The test screen can be equipped with 1-6 layers of screen frame, and the drugs can be divided into 2-7 grades. In the pharmaceutical process, the crushed raw materials are screened. Most of the particles are not uniform after crushing. Most of the particles need to be screened and detected by equipment. After crushing, the particle size of raw materials is not uniform, and it needs sieving before mixing. In the process of drug production, test screening plays a role in powder screening to reach the granularity of qualified materials. Including raw materials, granules of production process, and filtration screening of finished products. The concrete steps can be divided into three parts:

Step 1: Material Selection - Material Screening

In the selection of raw materials, most of the machines used by manufacturers are not fine enough to screen raw materials, so that there are many impurities in the production process, or the raw materials can not be selected well, and the purity of pharmaceutical raw materials can not be well grasped, so test screening is needed.

Step 2: Production Process - Filtration and Screening

In the production process, due to various factors such as mechanical vibration, granular semi-finished products are easy to break into small pieces, or powder, affecting the output and quality. For liquids, it is more necessary to use test screens for filtering and screening, filtering out impurities, and detecting the content of finished products.

Step 3: Screening and testing of finished products

When the product is finished, it is necessary to select the drugs and pack the selected products better, so it is also necessary to test and screen.

The use of test screening in pharmaceutical industry has very strict requirements. It must meet the GMP production standard of pharmaceutical industry, which is related to whether the screened drugs will be contaminated.
