Tensile testing, revolutionized for rubber.

The CubeOne is LabsCubed's automated tensile testing machine for rubber and elastomers. Load up to 12 specimens at once and it measures thickness, grips and pulls each one unattended — with a force capacity of up to 1 kN, elongation up to 1000% and speeds up to 150 mm/s — while your team moves on to higher-value work.

Tensile testing to ASTM D412 and ISO 37, and tear testing to ASTM D624 (Die B and Die C), so the same machine covers your tensile and tear programs.

Both evaluate the stress-strain behavior of vulcanized rubber and thermoplastic elastomers. ASTM D412 is the primary method in North America; ISO 37 follows a similar approach and is more widely used in Europe and other regions. They use different test speeds and specimen dimensions, but serve the same purpose. Choosing between them depends on whether your project or customer follows North American or international quality standards.

ASTM D412 Method A dumbbells — Die C, the most common elastomer die, and the smaller Die D — the ISO 37 Type 2 dumbbell, and the ASTM D624 Die C and Die B tear specimens. Method B ring specimens are not supported; Method A is the more commonly used method.

A wide range of elastomers tested at ambient temperature, including natural rubber (NR), SBR, EPDM, NBR, neoprene and silicone (VMQ), from custom compounds to production batches.

Tensile strength, tensile stress at a given elongation (modulus), ultimate elongation, tensile set, and the full stress-strain curve. For highly elastic materials the test may not reach fracture, in which case the focus shifts to elongation and recovery characteristics.

The CubeOne supports two of the three: a video extensometer for precise, non-contact strain measurement, and crosshead displacement. An automated physical extensometer is not available on the CubeOne.

Temperature, humidity, and testing speed can all affect results and should be controlled. Specimen preparation matters too: dumbbells are typically die-cut from molded sheets or plaques, and should be cut so their length runs parallel to the extrusion grain direction.

The CubeOne is built for Lab Managers, Quality Directors and R&D Engineers at rubber compounders and processors with medium-to-high testing volumes — typically facilities running 50 or more rubber samples per day.

Most customers achieve a full return on investment in 18–24 months, driven by recovering up to 85% of technician testing time and by reducing costly scrap and rework through eliminating operator-induced variability.

Data is recorded instantly and can be reviewed on the machine's touchscreen or in the cloud-based LabsCubed Portal. Our software team integrates directly with your existing systems, including Alpha Workbench, Uncountable, SAP and other LIMS/ERP platforms.

The CubeOne is built for rubber and elastomers, with up to 1 kN of force and optimized for high-elongation materials. The CubeTen is engineered for rigid plastics and high-strength materials, with up to 10 kN of force and support for adhesive tests like Single Lap Shear and T-Peel.

No. LabsCubed has 10 years of comparative test data showing that our horizontal orientation delivers results identical to traditional vertical machines. The design is what enables high-speed robotic loading, and each system is precision-calibrated so gravity and friction have no impact on load readings.

Installing the CubeOne is simple: its compact frame sits on a bench and plugs into a standard 110 V outlet. A LabsCubed specialist performs on-site installation, calibration to ASTM standards and team training, followed by prompt remote support and annual on-site calibration services.
