A bottle burst tester is a device that simulates the effects of internal pressure or external impact by applying pressure to the bottle until it breaks in order to test the strength and durability of bottles. The tester typically includes a pressure chamber into which the bottle is inserted, a pressure source, such as a pump or compressor, and a gauge or sensor to measure the pressure.

The bottling industry uses the bottle burst tester to make sure that bottles can withstand the pressure of their contents as well as outside impacts during handling and transportation. As part of safety and regulatory compliance, including testing for adherence to industry standards like ASTM, ISO, and others, the burst strength of bottles is also measured.

The tester is suitable for use with bottles made of plastic, glass, and metal. To test the strength of the bottle under various conditions, either internal pressure, external pressure, or both
