The CS4+ is a four-channel, voltage-controlled stimulator engineered for precision, reproducibility, and versatility in muscle physiology, neuromuscular, and electrophysiology experiments. Its robust electronics and intuitive software control make it suitable both for complex experimental paradigms and routine lab workflows - from single-pulse contractions to multi-train fatigue protocols and synchronized multisite studies.

Why CS4+ Is Ideal for Research
  • High-precision, reproducible stimulation: With up to four independent channels and voltage-controlled output, CS4+ ensures consistent stimulus delivery — minimizing variability across trials and preparations.
  • ​Flexible protocol design: Whether you need single twitch pulses, continuous frequency stimulation, or custom train-pulse sequences, CS4+ supports all modes. This flexibility makes it suitable for a wide range of applications, including twitch kinetics, fatigue assays, neuromuscular-disease models, and vascular or smooth-muscle studies.
  • Multi-site and comparative experiments: The four independent channels allow you to stimulate multiple tissue samples in parallel or sequentially — ideal for comparative studies (e.g. treatment vs. control) or simultaneous multi-site stimulation. 
  • Seamless software integration: The supplied MyoPULSE software enables straightforward creation, saving, and deployment of stimulation protocols. Complex pulse trains (voltage, width, frequency, intervals) can be programmed and reused, improving throughput and reproducibility.
  • ​Synchronization with external lab equipment: Built-in input/output trigger ports enable precise coordination with other instruments (e.g., motorized bath systems, data acquisition units), making CS4+ ideal for integrated workflows and automation.
  • Compatibility: Designed to integrate with Danish Myo Technology (DMT) myograph/organ-bath systems (e.g. 840MD Muscle Strip System), but equally usable with third-party electrophysiology setups.

Typical Applications
  • Fatigue assays and contractility studies in striated muscle
  • ​Neuromuscular disease (NMD) models and neuromuscular junction studies
  • Electrophysiological stimulation of isolated tissue strips (skeletal, smooth muscle, vascular tissue)
  • ​Comparative or multi-sample experiments (e.g. drug vs. control, genetic vs. wild-type)
  • Studies requiring synchronized stimulation and data acquisition or concurrent mechanical manipulation
