Mechanical Testers
for Biomaterials & Soft Tissue Research
Biomaterials, soft tissues, and engineered constructs do not behave like the rigid materials many test frames are built around. They are often soft, direction-dependent, and physiologically-relevant, and their response can shift over time. CellScale’s mechanical testers are built for these realities, combining sensitive force measurement, research-focused fixtures, and imaging-ready workflows to help you generate defensible mechanical data.
Mechanical Testing Systems on the Benchtop
CellScale designs each platform below as a benchtop mechanical tester optimized for research environments where specimens are small, hydrated, and difficult to grip. Compared to other universal testing machines, our mechanical testing systems emphasize repeatable mounting, low-noise measurements, physiologically-relevant testing environments, and imaging integration so strain and deformation can be interpreted in the region that matters.
UniVert
MicroTester
Micro-scale mechanical testing system for tiny specimens and low-load protocols where alignment and contact definition govern the result. The MicroTester is a strong fit when your workflow demands low-force mechanical testing with integrated imaging for alignment, tracking, and interpretation.
BioTester
Planar biaxial biomechanical testing system for anisotropic soft tissues and biomaterials. The BioTester enables equibiaxial and non-equibiaxial loading with imaging-enabled strain measurement and hydrated, temperature-controlled testing conditions.
These three mechanical testing machines are designed to complement one another across specimen scale and loading mode, rather than overlap.
How to Choose A Mechanical Tester
Use the guide to narrow down which of our mechanical testers fits your sample size, loading mode, and data requirements. It can also help if you are weighing a universal materials testing machine against our mechanical testing machines for soft specimens.
When you need versatile uniaxial testing
Pick the UniVert for:
- A versatile uniaxial mechanical tester for low to high-force testing
- Broad load capability for testing methods from compression and tensile to puncture and fatigue testing
- Hydrated testing with optional temperature control
- Imaging-based strain measurement when crosshead displacement does not reflect gauge-region strain
Many labs choose the UniVert when they need one mechanical testing machine to cover a broad range of uniaxial methods on the benchtop.
When you need micro-scale, low-load experiments
Pick the MicroTester for:
- Micro-scale mechanical testing workflows where specimen size and handling drive repeatability
- Low-force mechanical testing to resolve subtle differences in delicate samples
- Imaging at the center of the workflow for alignment verification and deformation tracking
- Hydrated and temperature-controlled testing for sensitive constructs
The MicroTester is the right benchtop mechanical tester when your samples are too small or too delicate for conventional methods and test frames.
When you need planar biaxial mechanics
Pick the BioTester for:
- Two-axis loading to quantify anisotropy under physiologic-like conditions
- A biomechanical testing system optimized for soft tissue mounting and repeatability
- Equibiaxial and non-equibiaxial protocols in force or displacement control
- Imaging-enabled strain measurement, including DIC-style strain mapping
The BioTester is the preferred mechanical testing system when your research questions require planar biaxial loading rather than uniaxial simplifications.

Imaging for Biomechanical Testing System Workflows
In soft tissue and biomaterials research, the biggest errors often come from assuming that actuator displacement equals specimen strain. A research-grade biomechanical testing system should let you verify what the gauge region is actually doing, especially when samples slip, grips deform, or strain localizes outside the region of interest.
CellScale mechanical testers support imaging-enabled workflows to help you:
- Confirm alignment and contact during setup
- Measure strain in the gauge region rather than relying on crosshead displacement
- Track deformation during time-dependent protocols
- Quantify spatially varying strain fields using DIC-style approaches (configuration dependent)
For many labs, imaging is the practical difference between a generic materials testing machine and a biomechanical testing system designed for soft, hydrated samples.
Mechanical Testers Comparison
UniVert
Uniaxial tension, compression, fatigue, peel, and more testing on the benchtop, spanning delicate (ultra-low force down to 0.02 N) to higher-load protocols (up to 1000 N) with imaging-ready, hydrated configurations.
MicroTester
Micro-scale platform for low-force mechanical testing (down to 100 nN) where integrated imaging supports alignment, contact definition, and deformation tracking.
BioTester
Planar biaxial biomechanical testing system for anisotropic tissues and biomaterials, supporting equibiaxial and non-equibiaxial protocols (from 0.5 N to 200 N force capacity) with hydrated testing.
Accessories and Software That Expand Benchtop Mechanical Tester Workflows
A key advantage of our research-focused mechanical testers is the ability to expand capability without replacing the base frame.
Eclipse Ultra-Low Force Sensor
The Eclipse supports ultra-low force testing (down to 0.02 N) for delicate specimens and protects against overload in protocols that push into the lowest force regimes. If your experiments need low-force mechanical testing at a scale a little larger than what the MicroTester excels at, then using the Eclipse with the UniVert is a great way to make those measurements practical and repeatable.
UniVert XY Stage
The XY Stage enables automated position mapping on the UniVert system. It improves positioning and alignment workflows, especially when fixture setup and consistent placement affect repeatability (with well plates, for example). For labs using a UniVert as their primary benchtop mechanical tester, the XY Stage can reduce setup variability across operators and specimen batches.
Data Analysis Software
Post-test analysis matters as much as acquisition when you are comparing cohorts, materials batches, or protocol variants. CellScale provides a lifetime license to our Data Analysis software with our mechanical testers. This software supports curve review, test-to-test comparisons, and reporting outputs suited to research documentation, especially when imaging-based strain measurement is part of the workflow.
Relevant Testing Methods
The right mechanical tester choice often depends on the test method, specimen geometry, and whether you need imaging-based strain tracking. Explore the testing method pages below for protocol-level guidance that applies across our benchtop mechanical testers, micro-scale platforms, biaxial setups, and mechanical stimulation bioreactors.
FAQs About Mechanical Testers
Which benchtop mechanical tester should I choose?
If you need broad uniaxial capabilities, start with the UniVert. If your samples are micro-scale or require very small forces, the MicroTester is often better suited. If you need two-axis loading for anisotropic tissues, the BioTester is the appropriate benchtop mechanical tester platform.
Can these mechanical testing systems run hydrated experiments?
Yes. Hydration is central for many biomaterials and tissue protocols, and our mechanical testers are commonly configured with media baths that include optional temperature control depending on platform and setup.
When is low-force mechanical testing essential?
Low-force mechanical testing becomes essential when small force differences encode meaningful biology or material changes, or when specimens are too delicate for higher-capacity frames. It is common for compliant hydrogels, thin membranes, microtissues, and other delicate constructs.
What makes a biomechanical testing system different for soft tissue research?
A biomechanical testing system is optimized for soft specimen mounting, repeatability under hydration, and strain measurement approaches that reflect gauge-region deformation. Imaging-enabled strain measurement and tissue-appropriate fixtures are often key differentiators. Universal testing machines are rarely optimized for soft materials and biomaterials.
