WPI is taking strides forward, bringing together an offering of the latest research tools for muscle physiology studies. To the long-time standard Myobath system, WPI now adds a biaxial tester and the line of Scientific Instruments-Heidelberg equipment.

Biaxial Tester
The BioTester5000, a biaxial testing device, offers a complete system for testing tiny biological specimens and analyzing the test results. Skin, ligaments, blood vessels, heart valves, sclera, membranes, scaffolds - BioTester 5000 can test any planar biological or replacement tissue. This system has a uniquely designed "BioRake" system that makes it easy to mount tiny samples. The unique tungsten BioRakes easily pierce the toughest and most delicate soft tissue samples and provide distributed attachment sites across the geometry of the sample for uniform attachment and deformation across the edge of the sample. The sharp rakes will not damage fragile samples.

SI-H Line of Products
In addition to a complete line of force transducers, mounting clips and accessories, SI-H equipment includes complete systems for a Simple Muscle Bath, Basic Muscle testing, Advanced Muscle research, Long-Term Incubation studies, Fibermic testing and an ATPase Muscle System. These systems are of modular design, making it easy to custom build a system that can be modified in the future as research needs change.

The Standard SI-H Muscle Research System performs mechanical and optical measurements on intact muscles, and the Basic Research System provides a low-cost system for mechanical measurements on intact muscles.

Combining the versatility of the KG transducers and a solid platform for mechanical studies, the SI-H Muscle Tester (Basic Research System) can be equipped with a linear motor and laser diode for running advanced muscle studies. It features:

• A small footprint and economical setup
• Data recording and analysis
• Controlled heating from 30-42C, and optional cooling to 5C
• Modular design for flexibility in upgrading
• Expandable with a stimulator and tetanizer for intact muscle stimulation, or a laser diode for sarcomere spacing studies in contracting muscles

The Standard Muscle Research System for intact living muscle preparations includes all the functionality of the Muscle Tester and is equipped for optical measures, too. In addition it can be outfitted with photometers, a laser diode and a linear motor. It features:

• Data recording and analysis
• Modular design for flexibility for upgrading
• Add a linear motor for muscle length perturbation studies
• Add a stimulator and tetanizer for intact muscle stimulation
• Add a photometer for intracellular calcium studies
• Add a cuvette system for intact muscle rapid cooling contractures
• Add a temperature jump system for skinned muscle fibers
• Add a gradient maker for calcium studies
• Add a laser diode for sarcomere spacing studies in contracting muscles
• Add a laser-controlled perfusion system for highly-accurate, low-force measurements
