Why choose CS4+
Focused stimulation control for compact ex vivo workflows
The CS4+ is intended for laboratories that need controlled and repeatable stimulation across up to four preparations without the additional capacity of an eight-channel setup.
Constant-voltage output
Apply controlled voltage stimulation where reproducible electrical input is part of the experimental endpoint.
Flexible pulse formats
Configure single-pulse, continuous-frequency and train-pulse protocols for different tissue and study requirements.
MyoPULSE control
Program, save and retrieve stimulation protocols to support consistency across users and experimental sessions.
Trigger functions
Coordinate stimulation with compatible acquisition and recording equipment using input and output trigger functions.
DMT system integration
Configure the stimulator with system-specific chamber covers, electrodes or mounting accessories.
System overview
Controlled stimulation matched to the preparation and chamber
The CS4+ supplies the electrical stimulation output, while MyoPULSE defines the protocol and the selected electrode accessory delivers the stimulus to the mounted preparation.
The correct configuration depends on the DMT system, chamber design, preparation type, required electrode geometry and intended stimulation protocol.
Four independent channels
Apply stimulation across up to four compatible preparations or
experimental chambers.
Mono or bipolar output
Select the appropriate output mode for the stimulation workflow.
Protocol software
Use MyoPULSE to configure, save and retrieve stimulation
procedures.
Electrode accessories
Match chamber covers, electrodes or electrode jaws to the DMT
system and biological preparation.
Synchronization
Use trigger input and output functions to coordinate stimulation
with compatible recording equipment.
Electrode accessories
Chamber covers and electrodes for different DMT workflows
Electrode accessories are selected according to the DMT system, chamber format and preparation. The final configuration should be confirmed before ordering.
Wire myograph
Chamber cover with electrodes
Electrode-cover option for compatible wire myograph stimulation workflows.
840MD
Muscle strip stimulation cover
Chamber-cover option for compatible MyoDynamics muscle strip stimulation workflows.
Pressure myograph
114P electrode cover
Electrode-cover option for compatible pressure myograph stimulation workflows.
820MO
Organ bath stimulation cover
Electrode-cover option for compatible organ bath stimulation workflows.
Accessory
Mounting jaws with electrodes
Jaw-based electrode accessory for compatible vessel, muscle or tissue stimulation configurations.
CS4+
Four-channel stimulation unit
Compact constant-voltage stimulator controlled through MyoPULSE software.
Typical applications
Electrical stimulation across muscle, vascular and tissue research
The CS4+ supports stimulation workflows where controlled electrical input is required as part of the biological endpoint.
01
Muscle contractility and twitch response
Apply controlled electrical stimulation to assess contraction, twitch characteristics and force development in muscle preparations.
02
Fatigue and recovery
Use train-pulse protocols to study repeated contraction, fatigue development and recovery.
03
Vascular and perivascular stimulation
Support studies involving vascular smooth muscle, perivascular nerves and vascular-neuromuscular function.
04
Organ bath and tissue stimulation
Stimulate mounted tissue preparations in compatible organ bath and myograph workflows.
05
Comparative protocols
Use four channels for treatment-control comparisons, protocol optimization and focused pilot studies.
06
Teaching and training
Demonstrate controlled stimulation principles in compact teaching or practical training setups.
MyoPULSE workflow
Program, save and repeat stimulation protocols
The CS4+ is controlled through MyoPULSE. Researchers can configure stimulation parameters, save protocols and retrieve them for repeated use, supporting standardized procedures across users, study days and experimental groups.
Protocol programming
Define voltage, pulse width, frequency, train structure and
timing parameters.
Protocol storage
Save stimulation procedures for reuse in later experiments.
Protocol retrieval
Reload established settings to reduce manual setup variation.
Channel control
Configure stimulation within the four-channel CS4+ workflow.
Trigger synchronization
Coordinate stimulation events with compatible acquisition and
recording equipment.
Protocol types
From a single twitch to complex train stimulation
Select the protocol format that matches the preparation and experimental endpoint.
Single pulse
Use a defined individual voltage pulse for twitch-response, threshold and simple stimulation studies.
Continuous frequency
Apply repeated stimulation at a controlled frequency for frequency-dependent response studies.
Train pulse
Configure pulses, trains and groups for fatigue, tetanic contraction and more complex protocols.
Trigger functions
Use input and output triggers to synchronize stimulation with external experimental equipment.
