ASTM D3330 Adhesion Test Method

ASTM D3330 standard is to test peel adhesion of the pressure-sensitive tape. ASTM D3330 Standard Test Method In terms of ASTM D3330, there are six test methods with different conditions required and the type of pressure-sensitive. Test method A measures the adherence of a single-coated tape which applies to a standard test panel with controlled pressure as the tape is peeled at 180 angles. Test method B measures the adherence to the backing of a single-coated tape. Test method B is similar to test method A. The difference between the two is that one tape is applied to the backing of another tape. Then, the rest process is the same as that of test method A. Test Method C is designed for double-coated tapes which consist of face side and liner side. To test adherence of the face side, the face side of the tape is down and applied to a stainless steel panel, remove the liner and put a trip of polyester film onto the liner side. The do the p

Study on the air tightness of ampoules

The use of ampoules to seal vaccines, serums, etc. is the last step to the market, and it is also a key step. The sealing of the packaging is very important to the quality of medical reagents, and it is also related to the health of patients and the production company. Reputation and credibility. The DK-190 headspace gas analyzer produced by Jinan Saicheng Instrument is equipped with high-precision imported sensors, which pioneered the use of handheld design, which can realize the efficient and convenient detection and analysis of the headspace of the ampoule, and then obtain the ampoule. The tightness of the bottle provides a guarantee for the quality control of ampoules. The following article introduces the principle and research method of using this product to analyze the headspace of ampoules. 1. Research background and significance The development of modern medical technology has brought great convenience to people's healthy life, especially the emergence of vaccine technolog
