The barrier properties of medical device packaging refer to the barrier effect of packaging materials on permeable substances such as gases (such as oxygen) and liquids (water vapor). Barrier performance is an important factor affecting the quality of products during their shelf life. The instrument information list is as follows:

1. PERME Bomi-DM2/330 dual method gas permeability tester: pressure difference and isobaric dual method testing, used for gas permeability testing of plastic film, composite film and other films, sheet materials and finished containers. Three chamber independent, automatic, temperature controlled, arbitrary temperature data fitting, supporting centralized management of LAN data, product.

2. PERME BOMI-OX2/230 Oxygen Transmittance Testing System: Coulombic principle, isobaric method to test the oxygen permeability of films, sheet materials, and packaging containers such as bottles, bags, cans, and boxes. Host and satellite mode, one host can connect nine satellite machines and achieve simultaneous testing of thirty samples.

3. The VAC-V series differential pressure gas permeameter is used to measure the gas permeation rates of O2, N2, CO2, and other gases in plastic films, sheets, composite membranes, and other materials. Principle of pressure difference method. This series includes models such as VAC-V1, VAC-V2, VAC-V3, etc.

4. PERME-W3/330 Water Vapor Transmission Rate Testing System: Used for measuring the water vapor transmission rate of films, sheet materials, and packaging containers such as bottles, bags, cans, and boxes. Host and satellite mode, one host can connect nine satellite machines and achieve simultaneous testing of thirty samples.

5. TSY-T series moisture permeability tester: used to test the water vapor transmission rate of various packaging materials and polymer products such as films and composite films; Temperature control, fully automatic; Computer monitoring and weight method principles. This series includes models such as TSY-T1H, TSY-T1L, TSY-T3, etc.
