The muscle tester is an entry level cost effective system in the muscle research field with remarkable capabilities. It combines the versatility of the KG transducer series (resolution from 0.4 µN up to forces of 2N) with a solid platform for mechanical measurements on intact muscle. It can be equipped with a linear motor and laser diode for running advanced muscle studies. A range of perfusion cuvette and temperature control options provide a wide range of possible applications.

KEY FEATURES:

• Small footprint economical system for the study of intact muscle preparations.
• Complete turnkey system with data recording & analysis/evaluation of data available
• Controlled heating 30-42C is standard and cooling option to 5C optional.
• Expandable with linear motor for muscle length perturbation studies
• Expandable with a stimulator & tetanizer for intact muscle stimulation
• Expandable with a laser diode for sarcomere spacing studies in contracting muscle.
• Expandable in the future due to its modular design.

KEY EXPERIMENTS / MUSCLE Parameters:

1) Measure intact muscle responses to electrical stimulation or tetanus. Measure myomechanical properties of contracting and relaxing muscle strips.

2) Twitch amplitude and kinetics analysis, time to peak, (50%) relaxation velocities, starling curve, diastolic force development with Software Muscledata..

3) A linear motor plus control units can be adapted to measure mechanical muscle properties such as Slack-test, Isotonic release, Constant velocity release, Stretch release, vibration studies, after-loaded contractions and eccentric contractions (intact muscle) background information

4) Simultaneous measurement of the Sarcomere length is possible by laser diode diffraction.

Instrument Control can be via hardware (Motor Action Control Panel) so you can use your own data acquisition system and software or via our integrated package (DAS/MuscleData/Gradient) that controls all hardware and records all muscle data and optical recordings.
