eXpert 4000 | MicroTester

Many industrial sectors are driving innovations in new materials from biomaterials, bone, fibers, threads, thin films, wire and more. However, that innovation requires measuring the mechanical properties of miniature samples. Few materials testing systems are able to measure very low forces and small displacements on samples that can often be difficult to hold. Furthermore, many researchers also have a need to record microscopic material behavior while the sample is under load. The line of eXpert 4000 series MicroTest Systems are ideally suited to meet these demanding testing requirements.

  • Miniature design, fits in the palm of your hand
  • Adaptable to micro scope stages
  • Perform tension, compression and bend tests
  • Capacities up to 5kN; Capable of milligram low force testing
  • Speeds up to 500 mm/min

Featured Configurations

eXpert 4200 Universal Testing Machine

eXpert 4000 models are available in four standard force capacities and are commonly customized for unique applications. This featured configuration has a 500N capacity and can go up to 500 mm/min. Dual active crossheads move in opposing directions so the center of the specimen remains stationary.  Depending on the material being tested, customers may choose from various clamps and fixtures to test biomaterials, wire, textiles, plastics, films, foils and more.

  • Universal testing machine designed for miniature specimen testing
  • Capacity up to 500 N (112 lbf)
  • Speeds up to 500 mm/min (20 in/min)

eXpert 4000 systems can be configured to fit in new or existing environmental chambers. In this featured configuration, frame components and tensile grips are rated up to 280˚C. The F-280DT environmental chamber is the standard configuration and can test materials up to 350˚C. If cooling is needed, either LN2 or CO2 may be used. Environmental chamber dimensions and temperature ranges can be customized upon request.

  • Designed for use in environmental chamber
  • Capacity up to 5 kN (1,250 lbf)
  • Speeds up to 25 mm/min (1 in/min)

eXpert 4000 Electrodynamic Configuration

The eXpert 4900 7N Electrodynamic MicroTest System was designed to measure the viscoelastic properties of tissue specimens. The featured system is capable of cyclic frequencies up to 100Hz with 10nm displacement resolution. MTESTQuattro dynamic controller was used to conduct dynamic mechanical analysis by applying sinusoidal varying force to the tissue test specimen and measure the resulting strain response.

  • Electrodynamic frame and components
  • Capacity up to 7 N (1.5 lbf)
  • Cyclic frequencies up to 100Hz

eXpert 4000 with Digital Microscope

The featured eXpert 4000 series 45N horizontal configuration is equipped with a 200x microscope for recording the specimen break when testing the strength of individual stent welds. With opposing moving crossheads, the center of the specimen never moves; a necessary feature when the MicroTester is used with a microscope to measure strain. In addition, a custom grip assembly was engineered and included with the system to quickly load each specimen, isolate a weld, and clamp the surrounding wire.

  • Designed to work with a microscope
  • Capacity up to 45 N (10 lbf)
  • Speeds up to 25 mm/min (1 in/min)

eXpert 4000 Axial-Torsion Configuration

eXpert 4000 series multiaxial configuration is designed for axial-torsion testing and features the MTESTQuattro axial-torsion controller and software. The system is built to perform material testing in the customer’s SEM. The axial force capacity of the system is 1.5kN and maximum axial speed is 5 mm/min. Torque capacity is 0.5Nm and maximum rotation speed is 2.7 rpm. System includes integral encoders and limit switches. An optional safety shield can also be added as an enclosure.

  • Designed for axial-torsion testing
  • Axial capacity up to 1.5 kN (335 lbf), torque capacity up to 0.5Nm
  • Axial speeds up to 5 mm/min (0.2 in/min), rotational speed up to 2.7 rpm

eXpert 4000 Heated Configuration

The heated eXpert 4200 MicroTest System was engineered to perform Electron Backscatter Diffraction (EBSD) Analysis in Zeiss Supra 55 SEM. High temperature grips able to accommodate temperatures up to 650˚C were oriented in 30 degree increments from the horizontal and the load cell was mounted on the opposite side of the frame to provide adequate test space inside the chamber. Another factor taken into account to maximize test space was the clearance between the eXpert 4200 frame and the chamber doorway when clamping the specimen in the grips.

  • Heated configuration for EBSD analysis
  • Capacity up to 2.2 kN (500 lbf)
  • Speeds up to 3 mm/min (0.12 in/min)

eXpert 4000 in Heated Saline Bath

The eXpert 4200 series instruments can be configured for use in temperature controlled saline baths. The featured configuration sits atop an Olympus IX-73 XYZ stage and includes a saline bath designed per customer specifications. MicroTester grips are submerged in water, giving the user the desired test space inside the temperature controlled saline bath. The testing frame and the mini load cell have a force capacity of 1kN and can be configured to run testing at speeds up to 25 mm/min.

  • Designed for use in temperature controlled saline bath and on a microscope system
  • Capacity up to 1 kN (225 lbf)
  • Speeds up to 25 mm/min (1 in/min)
