WPI SI-MT Basic Muscle Tester

WPI SI-MT Basic Muscle Tester

A convenient platform for all standard mechanical experiments on intact muscle preparations

World Precision Instruments

It is the basic muscle research system, which can be configured to study muscle strips or small whole muscles. The SI-MT has a modular design, like the SI-MKB, which permits it to be configured for turnkey solutions for specific applications. The system is built on a solid platform making precise mechanical and optical measurements easy. Like the Cell Tester and the SI-MKB systems, the SIMT uses SI-KG optical force transducers and is constructed with corrosion-free materials (stainless steel, anodized aluminum and plastic).

The SI-MT has:

  • Temperature-controlled cuvettes for proper tissue maintenance
  • Stimulation electrodes (field or point) that are integrated into the cuvette or the tissue mounts
  • Configurations for studying skeletal, cardiac and smooth muscles (either strips or rings)
  • Configurations with specific components, like a linear motor or a stimulator, for measuring (a) Responses to electrical stimulation, including tetany (b) Isometric force and mechanical properties of contracting and relaxing muscle strips (c) Isotonic force and the effects of constant load (d) Twitch amplitude and kinetics, like contraction and relaxation times and velocities (e) Slack, quick stretch-release, constant velocity and eccentric contraction tests (f) Afterloaded contractions from cardiac muscles (g) Vibrational studies that simulate unloaded muscle shortening
  • A configuration with a laser diode and detector, for measuring sarcomere length/spacing by laser diffraction at the same time muscle force is measured
  • A Labtrax 8/16 data acquisition system and MDAC software for: (a) Recording signals from the force transducer, and the motor position monitor, through four analog inputs (b) Controlling the stimulator or an external stimulus isolator, through an analog output (c) Controlling the position of the linear motor through a second analog output (d) Controlling other devices through two digital outputs
