Fully Automatic Tensile Testing Machine "Strograph AE Elastomer"

Fully Automatic Tensile Testing Machine "Strograph AE Elastomer"

This is a testing machine that automatically conducts tensile tests on soft materials such as elastomers.

● By setting the test specimens on the tray, all processes from dimension measurement ⇒ chucking ⇒ gauge length extension measurement ⇒ removal of test specimens ⇒ data processing will be performed automatically. ● Continuous testing of 120 test specimens is possible. It contributes to labor-saving, efficiency improvement, and enhanced reproducibility in measurement tasks. ● A non-contact* (laser type) gauge length extension meter is available as an option. ● Compact space-saving design.

New product: Laboplast Mill Micro 4N100 now on sale.

  • PRODUCT

We started selling the new product, Laboplast Mill Micro 4N100, on September 10, 2025. Like the previous model, Laboplast Mill Micro, it allows for the evaluation of mixing and extrusion characteristics with a small amount of resin. While maintaining compatibility, we have reviewed the torque detection mechanism and control method, making it easier to use and enabling more reproducible prototypes than the previous model. We also have a physical unit available at our Tokyo factory, so please feel free to contact us.
