Steinfurth Ball Impact Tester

Standardized impact tests on bottle closures

General Details

The Steinfurth Ball Impact Tester allows standardized impact tests for bottle closures. The bottle to be tested is held in a box, which can be swung from a horizontal to a vertical position in steps of 5 degrees.


– The impact weight, a steel ball with defined mass and diameter, is manually dropped through a drop pipe. The kinetic energy of the impact is defined by the length of the pipe and the mass of the weight. The drop pipe can be adjusted to select the desired target point.
