Steinfurth Opening Performance Tester

(OPT 180) - testing of bottle closures

  • Opening Performance Test 180
  • Opening Performance Test 180

For beverage filler and closure manufacturer, the opening performance of twist closures is an important quality parameter. The OPT 180 opens a closure quickly and reproducibly on the original thread. Meanwhile, it records torque, rotation angle, vertical movement, pressure and temperature.

The OPT doesn’t exert any vertical force on the closure, making a blow-off-effect clearly visible. The recorded data is transferred to a PC and evaluated there.


- A cut preform or bottle neck is fitted to a test bottle. The gas volume is adjusted by filling the bottle.
- The OPT 180 closes automatically the bottle, pressurizes the test bottle and opens the closure after a short period of time.
