MTS Introduces The Bionix Envirobath

Versatile, easy-to-use new accessory streamlines testing of biomedical specimens in fluids heated to body temperatures.

Eden Prairie, Minn. – February 10, 2009 – MTS Systems Corporation (NASDAQ: MTSC) today introduced the Bionix® EnviroBath, a new bath accessory designed to facilitate the efficient and accurate mechanical testing of biomedical and general material specimens in fluids heated to body temperatures.

“We engineered the new EnviroBath to be versatile, easy-to-use and reliable,” said Laura Bock Carlson, MTS accessories product manager. “This new bath simplifies fluid-based biomedical testing while fulfilling a broad spectrum of test requirements across a variety of mechanical test platforms.”

Available in 1, 6 and 10 liter volume configurations, the versatile EnviroBath is well suited for a wide range of test applications and specimen sizes. A universal adapter design ensures full compatibility with MTS electromechanical and servohydraulic load frames, a variety of Bionix grips and fixtures and even electromechanical test systems from other manufacturers.

The EnviroBath streamlines test operations with convenient, leak-proof front and back access panels that enable easy installation and change out of grips, fixtures and test specimens. Filling and draining the EnviroBath is both controlled and quick, and easy disassembly simplifies cleaning and regular maintenance. A highly reliable fluid temperature control system ensures that specimen temperatures remain constant throughout the duration of the test.

A host of optional features further extend the utility of the EnviroBath. These include a protein-based fluid handling system, an optical window for use with video or laser extensometers, and bath-mounted temperature monitoring.
