Mechanical Testing - BioTester

The BioTester is a benchtop biaxial testing machine and planar biaxial testing system for soft tissue and soft synthetic material mechanical testing.

BioTester Data Sheet

The BioTester biaxial testing machine is a dedicated platform for planar biaxial testing of soft tissues, biomaterials, and synthetics that exhibit direction-dependent structure. Originally designed for soft tissue biomechanical testing, the BioTester combines synchronized actuation, specimen mounting options, imaging-based strain measurement, and temperature-controlled media capabilities to support repeatable biaxial protocols without building custom equipment. Our patented BioRakes feature quick and reliable sample attachment for repeatable results.

Many biomaterials and biological tissues are anisotropic, non-heterogeneous, and sensitive to handling. A planar biaxial testing system helps quantify direction-dependent mechanics and coupling effects that may be missed in uniaxial tests. The BioTester platform is a biaxial testing machine series engineered specifically for tissue biomechanics testing, with fixtures and workflows intended to reduce setup variability and improve comparability across specimens and cohorts.

• Planar biaxial testing machine for soft tissue and anisotropic biomaterials
• Equibiaxial and non-equibiaxial protocols with displacement or force control
• Purpose-built soft tissue mounting options including patented BioRakes
• Imaging-enabled strain measurement for real-time tracking and DIC
• Hydrated, temperature-controlled media bath capabilities

The BioTester is used when you need to mechanically characterize a soft specimen in two directions at the same time. It is a planar biaxial testing system for soft material and soft tissue biomechanical testing, where one-axis pulls do not tell the whole story. Labs use it to compare how a tissue behaves in physiologic-like conditions, and to run time-based routines under two-axis loading. It combines synchronized two-axis loading with mounting tools (including the patented BioRakes) that keep setup consistent from sample to sample, and it supports image-based strain measurement when actuator motion is not a reliable proxy.

The BioTester is used with planar soft tissues such as pericardium, valve leaflets, vessel wall samples, and skin. It is also used for engineered patches and scaffolds, soft polymer films, tissue-mimetic biomaterials prepared as flat specimens, as well as soft polymers and other general-purpose materials.
