ElectroForce 3200 Series Test Instrument
MDT  uses Bose ELectroForce 3200 Test Instruments for low force, high frequency applications.  Utilizing a linear motor drive, these testers are ideal for applications requiring a combination of high frequency, enhanced fidelity, and high cycle count. They are capable of loads as high as 450N and have been used in applications requiring extraordinarily high cycle counts. Various test fixture designs for the 3200 can accommodate up to 16 samples, depending on the fixture. The instrument controls and monitors displacement or load.  For multi-specimen applications, transducers for monitoring each specimen can be added to provide individual data collection.

Typical test applications for the ElectroForce 3200 include:

• Strength Characterization Testing for Intravascular Devices
• Orthopedic Testing
• Custom Mechanical Tests

ElectroForce 3300-AT Series Test Instrument
The ELF 3300-AT (axial/torsion) instruments retain the high frequency/high cycle capabilities of the ElectroForce 3200 while providing higher force capability and longer displacement.  The ELF 3300-AT  includes a rotary motor and is capable of applying simultaneous axial and torsional loads.  The axes can also be run independently and operate at values as high as 100 Hz and 15Hz respectively. Up to eight (8) revolutions of torsion can be applied in one direction during static or cyclic testing.  The 3300-AT can be used in a variety of applications.  and MDT has developed fixtures which adapt the torsion motion to bending enabling bend testing of medical devices in various configurations.   Common medical device testing applications requiring greater strains such as pacemaker lead testing or large stent graft bend tests are often performed on the ELF 3300 using fixtures that accommodate as many as 16 specimens. The instrument controls and monitors displacement or load.  For multi-specimen applications, transducers for monitoring each specimen can be added to provide individual data collection.

 Conventional test applications for the ElectroForce 3300-AT include:

• In Vitro Simulated Gait Motion for Intravascular Devices
• In Vitro Simulated Tension/Compression for Intravascular Devices
• In Vitro Simulated Torsion/Rotation for Intravascular Devices
• In Vitro Simulated Bending for Intravascular Devices
• Strength Characterization Testing for Intravascular Devices
• Orthopedic Testing 

Environmental control for ElectroForce Instruments:
Most tests require a controlled temperature or saline environment. MDT Services has chambers for testing in both air and saline at temperatures to 37C utilizing various baths, enclosures, special fixturing and modular heating/circulation systems.
