Quality, safety and cost of materials demand the effective testing of packaging materials to deformation or point of collapse. Our entry-level Top-load Tester, the TLT 2.5 kN, ensures that these requirements are met, providing high accuracy with repeatability and reliability of results. This model is ideal for testing to ASTM D2659 as well as Coca-Cola and PepsiCo in-house standards.

Key Features

  • Touch Screen tablet PC - easy programming for use on the production floor & minimal operator training required
  • Suitable for containers up to 5.28” (134 mm) diameter. Bespoke solutions for larger containers can be provided including crosshead extensions and larger base plates.
  • Samples of any shape can be tested including PET, HDPE, metal and cardboard containers
  • Defined platen positioning for ease of sample removal and placement
  • 5 customisable favourites for speedy access to testing
  • Free Height of container can be calculated automatically saving extra steps and time
  • Calculations such as ‘Free Height’, ‘Peak Load’ and 'Collapse Force' can be color coded for pass/fail
  • Automatic export of defined results minimises key strokes by the operator
  • Designed for repetitive testing on a production floor with ease of use and minimal maintenance costs 2.5 kN (550 lbf) capacity



  • The TLT 2.5 kN is ideal for conducting top-load tests on smaller items such as thin plastics and cardboards
  • Maximum Force: 2.5 kN
  • Maximum Travel: 500 mm (19.7”)*

“Our investment in the MultiTest-xt top-load test unit has paid for itself time and time again. The unit is so easy to use that no outside training was needed at start-up and training new operators was very minimal. This has resulted in no misjudgments from equipment set-up. The displayed graph makes it very easy to understand what is occurring during the test and aids in troubleshooting and correcting issues. The touch screen/computer combination reduces the footprint to less than half the size of our older unit. Overall the unit gives great performance at a very competitive price.”
