eXpert 4000
Static and Dynamic MicroTesters,
Up to 5 kN Capacity
As innovation accelerates across biomaterials, bone, fibers, thin films, wire, and more, researchers and quality professionals increasingly need precise measurement of miniature specimens. ADMET’s eXpert 4000 Series delivers exceptional value for small-sample, low-force applications where conventional UTMs fall short. With capacities up to 5 kN, flexible fixturing, and advanced controllers, the eXpert 4000 supports static, quasi-static, and cyclic fatigue testing for a wide range of small-scale materials, from tissues and biomaterials to metals and thin films.
Made for Difficult Materials and Unique Geometries.
Testing at micro-scale introduces real challenges: very low forces, infinitesimal displacements, and samples that are delicate and difficult to grip. Many conventional testing systems lack the sensitivity and control required, especially when combined with the need to observe microscopic material behavior under load. The eXpert 4000 Series is purpose-built to solve these problems. These systems integrate seamlessly with high-magnification imaging tools, including optical microscopes, SEMs, and vacuum-based environments. Optional heating, cooling, and environmental baths enable testing under a wide range of in-situ conditions.
Modular Frame and Actuator Design
Design modularity is a core value in all of our MicroTester products. Every MicroTester can fit comfortably on a lab bench with plenty of room to spare. You’ll find that with the clean and compact designs we provided, installation, sample handling, test execution, and analysis is easy..
Microscope and Imaging Integrations
ADMET MicroTesters can be integrated with optical stage microscopes, scanning electron microscopes (SEMs), synchrotron beamlines, and other imaging systems from the customer. Additionally, USB microscope options are offered if close-up viewing of a sample is needed.
Environmental Control Capabilities
Our MicroTesters are commonly fit with heating and cooling chambers, saline baths, and recirculating bioreactor environments. Depending on the need, ADMET uses both off-the-shelf and custom solutions for environmental control. We will work closely with you to understand the requirement and deliver the best solution possible.
Advanced Control Systems
ADMET Materials Testing Systems are built around closed-loop servo control, enabling precise regulation of load, position, and strain throughout a test. MTESTQuattro and eP2 are designed to serve different testing needs, from software-driven, highly configurable test environments to streamlined digital control for routine, high-volume work. MTESTQuattro is typically selected when advanced test sequencing, extensive data analysis, or custom methods are required, while eP2 is well suited for standardized tests where simplicity and throughput are priorities. Both platforms deliver reliable servo performance and real-time data acquisition, allowing users to choose the level of control and software capability needed for their applications.
MTESTQuattro
MTESTQuattro is the PC-based controller and materials testing software platform behind most ADMET materials testing systems. It delivers precise closed-loop control with an 8 kHz servo update rate, high-resolution data acquisition, and built-in ASTM/ISO test workflows. The blue controller manages real-time machine motion and translates sensor inputs, while the software handles test setup, execution, analysis, and reporting. Together, they enable repeatable tensile, compression, flexural, fatigue, and custom test methods for both routine QA and advanced R&D, making MTESTQuattro a scalable solution for new test systems and retrofit applications alike.
eP2 Digital Controller
The eP2 is a standalone closed-loop servo controller for mechanical testing machines, providing direct load and position control at the frame without relying on a PC. Tests are configured on the controller using preset methods and numeric setpoints, with control loops running up to 1 kHz for stable force, position, and strain control. During the test, data is logged internally and then transferred to GaugeSafe software via USB for plotting, calculations, and reporting. The result is a turnkey testing core with fast setup, repeatable control, and a clean data path from actuator to report.
Precise Control
Both control platforms use closed-loop servo control to regulate load, position, and strain throughout a test. High update rates and responsive feedback help maintain stable loading during ramps, holds, and cyclic profiles. This level of control supports accurate, repeatable results across a wide range of materials testing applications. Consistent control behavior also reduces test-to-test variability when running long series or multi-specimen programs.
Intuitive Test Setup
ADMET control systems are designed to streamline test setup while maintaining flexibility. Standard test methods can be configured quickly, and custom test sequences can be built as needed using the testing software. Clear workflows reduce setup time, limit operator error, and support consistent testing across users and shifts. Saved test configurations allow validated methods to be reused without rebuilding procedures for each run.
Powerful Analysis and Reporting
Test data is captured in real time and processed using built-in materials testing software aligned with ASTM and ISO requirements. Results can be reviewed, compared, and exported in standard formats for traceability. This supports audit-ready documentation for both research and quality-focused testing environments. Automated calculations and standardized reports help ensure results are interpreted consistently across projects and teams.

Long-term Value
With every purchase, ADMET offers free technical and application support for the life of your testing system. Whether you’re faced with a technical challenge or need an outside perspective on test design, we will partner with you to make your testing easy and successful.
Calibration Services
ADMET offers calibration services on new materials testing systems both before shipment and as a field service for any customer in need. Although ADMET utilizes the highest quality equipment available, regular calibration ensures that these components perform as required so the results generated can be trusted with confidence. A list of ADMET’s accredited calibration scope is available via the link.
Retrofit Capabilities
ADMET can extend the life of an aging testing system of any brand with our retrofit services. We often upgrade older systems with modern controllers, advanced software, and new fixturing to meet today’s materials testing needs. This extends lifespan, improves functionality, and improves the lifetime value of your investment. For a list of our retrofit capabilities, visit our retrofit webpage.
