TestResources applies modularity to a range of testing products, including systems for tissue testing and medical and orthopedic devices.
For TestResources (Shakopee, MN), the driving design principle behind its test systems is modularity. “The idea was to establish a business with a more flexible product line—we call it modular—where we can configure machines with a variety of components combined in different ways to meet each customer’s set of needs,” explains sales manager Ted Parrish.
Using modularity as its mantra since its inception 10 years ago, TestResources applies this design philosophy to a range of testing products, including systems suited for biomedical testing of tissues and medical and orthopedic devices. The advantages of such an approach revolve primarily around cost reductions enabled by standardization and the avoidance of ‘overbuilding’ a system for a specific customer’s needs, according to the company. Flexibility, customization, and the ability to easily augment systems to accommodate developing needs are also potential benefits.
Specializing in all-electric units, TestResources offers static and dynamic materials test, torsional test, and multiaxial test systems, in addition to a bevy of associated accessories. “In most of our systems, we use an all-electric type of system instead of a hydraulic system, which is generally preferred for biomedical testing applications,” Parrish says. “They are cleaner, less intrusive on the facility, and consume less power for the [amount of] work that they do.” Models for tension, compression, and fatigue testing are among the company’s main product lines.
While exhibiting at MD&M Minneapolis for the first time, TestResources will be highlighting the features of its 800L series, which include a compact footprint and versatile design. Users can also opt to pair the 800L with the company’s biobath in order to simulate in vivo conditions for more-accurate product testing. The systems typically test such products as biomaterials, orthopedic implants, tissues and artificial ligaments, and medical devices like catheters, heart valves, and stents.
“It’s a fun business to serve because it’s easy to relate to the products that our customers are testing, [as well as] what they do, how they help people, and how our machines help to further their purposes,” Parrish says.
