Test method for internal pressure resistance of pharmaceutical glass bottles

Molded infusion bottles and molded injection bottles should be molded for its production process, the use of quartz sand, borax in the kiln array machine made of glass bottles, the appearance and control bottles compared to the appearance of the bottle looks rougher. Domestic I.V. packaging to molded glass infusion bottles, pharmaceutical companies to complete the filling of drugs need to be high temperature sterilization, the liquid inside the bottle by the heat of the internal air pressure increases, in order to ensure the integrity of the medicinal glass bottles, medicinal molded bottles of internal pressure is also one of the pharmaceutical laboratory glass bottle testing project. Molded infusion bottles and molded injection bottles have internal pressure requirement of ISO 600Kpa.

Glass bottle internal pressure tester meets the relevant requirements of YBB00312002-2015 "soda-lime glass molded injection bottle" standard, there are two measurement methods in the standard of pharmaceutical packaging materials: the first method: the test of applying uniform internal pressure in a predetermined period of time, which is required to do the pass-through and incremental test, and the second method of increasing the internal pressure under a predetermined constant speed, which is required to do the pass-through and destructive test. Volume of larger infusion bottles, these two methods are required to test, the volume of smaller soda-lime glass with the first method can be, no need to do destructive testing.

It is understood that there is a specialized testing of glass bottles on the market to resist the internal pressure of the instrument - glass bottles to resist the internal pressure tester, the instrument through the internal pressure tester driven by servo motors in the hydraulic pump generated by the pressure through the pipeline in an equivalent manner were transmitted to the pressure sensor and the glass sample bottle being tested, the equipment controller from the pressure sensor real-time collection of Pressure signal and according to the value of the pressure signal to control the servo motor driven hydraulic pump so that the pressure change in the system in accordance with national standards and ISO standards require a linear increase until it reaches the pre-set value, in the process of pressurization or holding pressure to see if the bottle is ruptured to determine the quality of the bottle. It can also be used for bursting pressure test. It is suitable for molded glass bottles, such as infusion bottles, beer bottles, white wine bottles, beverage bottles, antibiotic bottles, cillin bottles, etc. It is a testing instrument for breweries, glass bottle manufacturers, quality inspection organizations and pharmaceutical manufacturers.
