Unlimited capability for all closure torque tests
Designed to run sophisticated routines for more demanding test procedures. Ideal for closure system product development and design optimisation
Ultimate accuracy and repeatability
Computer-controlled, motorised clockwise or anticlockwise torque application at constant velocity, combined with comprehensive calculation and evaluation tools to capture strategic events
Top-loading capability
Apply set loads during torque testing, particularly suitable for child-resistant closures
Versatile tester
The Vortex-i is used to test a variety of closures including metal ‘Stelvin’ caps on wine bottles, plastic tamper-evident closures on PET bottles, child-resistant (CRC) closures on pharmaceutical containers and corks

Unlimited capability for torque testing all closure system designs

The Vortex-i motorised torque testing system provides constant rotational speed to enable accurate, repeatable, closure torque measurement. Top-loading allows push and turn CRCs to be tested and the ability to write advanced test programs gives designers the power to optimise functionality.

Programming environment allows unique tests and calculations to be createdRun sophisticated routines for closure system product development and design optimisation.
  •  Build your own test program, unique to your closure system
  •  Gain accurate test data with constant motor-driven rotation
  •  Capture strategic events, reliably identify breakaway torque with fallback/sensitivity control
  •  Evaluate results in-depth, performing standard or bespoke calculations
Top loading allows the push force on the CRC to be set to then measure the torqueFor TE closures, Vortex has the sensitivity to detect:
  •  The applied torque as the closure is tightened
  •  The strip torque as the closure is overtightened
  •  The release (peak) torque as the first seal is overcome
  •  The slip and bridge torque where the tamper-evident band separates from the screw closure.

For CRCs, masses are added to the top-load carrier to apply a constant down force while rotating the closure and measuring the release torque.

Output custom formatted reports easilyWhen further evaluation of results is required, a range of calculations are available to help pinpoint areas of interest, for example to accurately differentiate between the breakaway torque peak and the tamper evident band breakage event. Standard and customisable report templates enable easy documentation creation, which can be stored and exported to Microsoft Excel® and SPC packages.
Console mode allows quick access to pre-programmed testsConsole Mode allows tests to be created very simply by selecting options from radio-buttons and drop-down boxes. A number of pre-configured calculations are available and can be included by simply clicking with the mouse. Console mode is ideal for use on the factory floor by operators who need only minimal training to load and run programs directly from one of the five “Favourite” buttons.
