AUTOMATIC CAP TORQUE TESTER

Sure Torque’s ST-LAB series is the most automated closure Torque Tester on the market, with the ability to handle the most varied container and closure types.

The newest models of the ST-LAB family have user configurable automatic Top Load control for testing Child Resistant closures.

Main features of the new ST-LAB:

– FDA CFR 21 part 11 compliant logging
– Unlimited internal memory with full result logging (not possible to delete results)
– Batch-based memory structure. Results can be recalled in by: Year/Month/Day/Batch
– Programmable Top Load control
– Application angle measurement 
– Fully automatic
– Quick testing (10-15 sec)
– Statistics on test type/sample type (average, sigma, cpk, in/under/over range)

The difference between the ST-LAB6 and the LAB5 is mainly the 21 CFR part 11 compiant logging and the memory capacity and structure. Main mechanical, control and change parts are the same by the LAB6 and the LAB5

Industries: Beverage, Food, Pharmaceutical, Packaging

Areas: Laboratory, Production

 Applications:

– Release torque testing without breaking seal integrity
– Child Resistant closure testing with programmable Top Load
– Automatic Application Angle measuring 
– Warranty ring application and breaking tests
– Precision capping

• FDA CFR 21 part 11 compliant logging

• Unlimited internal memory with full result logging (not possible to delete results)

• Batch-based memory structure. Results can be recalled in by: Year/Month/Day/Batch

• Release-application test without breaking the seal integrity of the product. This means: SAVING MONEY and ENVIRONMENT FRIENDLYNESS – the tested and re-torqued sample can be put back on the production line, instead of in the waste – see this savings table.

• Automatic top load control enables the simple and accurate testing of the Child Resistant closures.

• 100% operator independent testing

• All movements are fully automatic (not just the rotation, but also the container and closure gripping)

• Quick testing – test speed can be set over a wide range

• 10 different test receipts for the different products  

• Many included test modes

• Direct statistical analysis and report creating

• Possibility to add custom test modes at any time (upgrade-file can be sent in email)

Air supply: 6 Bar filtered air with 6 mm tube

Standard test modes:   

Release test
Range testing – Besides the exact release torque ,out of tolerance readings are indicated by colour signals

Application
Release-apply test. With this test mode it is possible to measure the initial release torque without damaging the temper-proof band and the sealing even on carbonated or aseptic products.

Apply-release test (for finding the relationship between the application and the release torque on several cap-container combinations)

Warranty Ring application and release tests

Strip test – The strip test mode measures the peak torque value, where threads break/deform in an on-torque/application cycle. In this way it is possible to measure the maximum torque that can be applied to a closure/container, without permanent damage of the closure/container threads.
Top load can be configured by for each test individually. By the combined tests top load can be set differentlyfor Application and Release!   

Additional test modes in the ‘Advanced Top Load’ option:

Application angle measurement

A release test where after passing the initial release torque the closure will be fully removed, and the original application angle will also be measured
