If high volume, repetitive testing is causing a bottleneck in your operation, automation can be vital. An investment in automation can allow you to load multiple samples for testing all at once, which can then directly impact your laboratory’s contribution to profit.

The Automated Linear Indexing System (ALIS) enables the loading of multiple test samples prior to testing and does not require constant supervision by the user during testing. It integrates seamlessly with a TA.XTPlus Texture Analyzer with quick and easy set-up and sample mounting.

In a typical example, test specimens are placed in bespoke support plates. Then, with prompted steps, conditions are set, tests are performed, and results are reported with little or no operator involvement. While tests are being run, your team can prepare further samples or evaluate results of previous tests.

See a video showing examples of how an Automated Linear Indexing System works.

The ALIS is available in two platform lengths, 250mm and 600mm. The platform can be moved and paused for the testing of each sample, or can be moved constantly at the same speed as the texture analyzer’s arm, as recommended for instances of peel testing, for example.

Measure Tape Peel Properties at Multiple Speeds within a Single Test

In the field of adhesive technology, the 90° peel test (FINAT No. 2) is one of the most commonly used tests. This measurement can be greatly simplified with ALIS, which makes possible a precise positioning of the measuring arm and measuring table. The speeds between the trigger and the table feed can also be changed within a single test, rather than having one test per peel speed, saving valuable testing time.

In addition to lipstick consistency, lipstick transfer and the application behavior of lip pencils are important factors. With the TA.XTPlus Texture Analyzer and the ALIS, you can precisely assess the transfer (or payoff) of the lipstick onto a defined surface. In this test, the lipstick is applied to a surface with a defined force. The ALIS table then triggers the movement, simulating the lipstick’s application. The movements of the table can be precisely controlled by the user, which provides greater flexibility in the test. Then the amount of the abraded lipstick mass can be determined by weighing the paper substrate before and after the test.
