DMT systems support different ex vivo workflows. The easiest way to choose the right category is to start with the biological preparation and the primary measurement endpoint.
This overview explains, at a glance, the difference between wire myographs, pressure myographs, organ bath and isolated tissue systems, and muscle strip or tissue mechanics systems.
Each category is built around a different experimental geometry and measurement principle.
Wire myographs are used when isolated vessels or smooth muscle preparations are mounted on wires or pins and force is measured under controlled isometric conditions.
Pressure myographs are used when a vessel should remain cannulated and pressurized, allowing diameter, wall mechanics, flow and pressure-dependent function to be studied.
Organ bath and isolated tissue systems are used when tissue viability, force measurement, chamber conditions and reproducible mounting are central to the experiment.
Muscle strip and tissue mechanics systems are used to study force generation, stretch response, relaxation-contraction kinetics and tensile properties.
Use this table as a first-pass guide before moving to the individual category pages.
| Category | Primary question | Typical preparation | Main measurement | Best fit when... | Go to page |
|---|---|---|---|---|---|
| Wire Myograph Systems | How does a vessel or smooth muscle preparation contract or relax under defined conditions? | Small arteries, resistance vessels, vascular rings and selected smooth muscle preparations. | Isometric force, concentration-response, contraction and relaxation. | You need vascular reactivity, endothelial function, smooth muscle pharmacology or reproducible ring-mounted vessel testing. | Wire systems › |
| Pressure Myograph Systems | How does an intact vessel behave when pressure, flow or diameter is controlled? | Cannulated arteries, veins and other intact vessel segments. | Diameter, lumen diameter, wall thickness, pressure-diameter relationships, flow and pulsation responses. | You need near-physiological pressure conditions, myogenic tone, flow-mediated responses or imaging of pressurized vessels. | Pressure systems › |
| Organ Bath and Isolated Tissue Systems | How does an isolated tissue respond to drugs, stimulation or physiological conditions? | Vessels, trachea, intestine, bladder, uterus, skeletal muscle, cardiac muscle and other isolated tissues. | Force response, contraction, relaxation and pharmacological reactivity. | You need flexible isolated tissue studies, larger ring or strip preparations, teaching workflows or multi-channel organ bath capacity. | Organ bath systems › |
| Muscle Strip and Tissue Mechanics Systems | How does tissue generate force, respond to stretch or fail under mechanical load? | Muscle strips, vascular tissue, tubular tissues and other mechanically tested preparations. | Force transients, length-tension, tensile strength, compliance, stiffness, viscoelasticity and contraction kinetics. | You need active muscle mechanics, electrical field stimulation, passive biomechanics, tissue pulling or tensile testing. | Muscle systems › |
In most cases, the right DMT category becomes clear when you define the endpoint first.
You want to measure vascular force responses from ring-mounted vessels, compare contraction and relaxation curves, assess endothelial function or run pharmacological reactivity studies.
Go to Wire Myograph Systems ›You need the vessel to remain intact and pressurized, and your endpoint depends on diameter, flow, wall mechanics, pressure response or vessel imaging.
Go to Pressure Myograph Systems ›Your preparation is an isolated tissue segment or organ-derived strip where contractility, relaxation, drug response, chamber volume or teaching simplicity are important.
Go to Organ Bath Systems ›Your endpoint is active muscle contraction, stimulation response, tissue stretch, tensile strength, stiffness, compliance or passive biomechanical behavior.
Go to Muscle Systems ›Each category page explains system fit, typical applications, product options and practical selection considerations in more detail.
For ring-mounted vessels, isometric force, vascular reactivity, endothelial function and smooth muscle pharmacology.
Open wire category ›For cannulated intact vessels, pressure-diameter relationships, myogenic tone, flow-mediated dilation and imaging workflows.
Open pressure category ›For contractile function, smooth muscle pharmacology, larger tissue preparations, teaching laboratories and multi-channel workflows.
Open organ bath category ›For muscle mechanics, stimulation response, tensile testing, compliance, stiffness and active or passive tissue mechanics.
Open muscle category ›Contact DMT with your tissue type, preparation size, primary endpoint, expected force or pressure range, stimulation needs and throughput requirements. DMT can help identify the right category and system configuration.
