Automated normalization
The 630MA automates the normalization procedure so preload tension and initial experimental conditions can be set in a standardized way after mounting and equilibration.
The DMT 630MA is a four-channel automated wire myograph for studying vascular function in small tubular segments. It combines classic isometric wire myography with automated normalization, integrated heating, gassing, drainage and direct data streaming for high-throughput vascular reactivity studies.
The 630MA is suited for laboratories that need reproducible small-vessel myography, standardized preload conditions and efficient handling of multiple vessel segments in parallel.

Four chambers support parallel vessel testing, treatment-control comparisons, concentration-response curves and studies where individual vessels must be tested separately.
The chamber design supports ring-mounted vessel segments and can also function as a small organ bath for compatible preparations.
Heating, gassing, drainage, force calibration, selectable force range and interface menu control are integrated into the 630MA workflow.
The system supports both jaws and pins, making it suitable for a range of vascular preparations and vessel sizes.
Multiple units can be arranged side by side and combined with the Buffer Filler System – 625FS for more efficient buffer exchange workflows.
Once vessels are dissected, cleaned and mounted in the four chambers, each segment is maintained under physiological conditions in acid-resistant stainless-steel chambers.
Temperature is maintained through built-in heating, gas inflow is individually controlled, and buffer drainage is handled through a vacuum connection and built-in manifold.

The 630MA is a 4-channel automated wire myograph designed to measure isometric force in small blood vessels and tissue rings. It combines high-throughput vascular function studies with automated normalization, helping researchers achieve more consistent and reproducible experimental conditions.
The 630MA is designed for small arteries, veins, and other ring-mounted tissue preparations. It supports both jaw and pin mounting, allowing researchers to study vessels from 30 µm to larger vascular and tissue ring preparations depending on the mounting configuration.
The system measures isometric force, vascular contraction, relaxation, endothelial function, concentration-response curves, and passive length-tension relationships. Four independent chambers allow multiple vessel preparations to be studied simultaneously under controlled conditions.
Normalization determines the optimal passive tension before beginning a wire myography experiment. The 630MA automates this process, helping standardize preload conditions across all four chambers. This improves reproducibility, reduces operator-to-operator variability, and saves valuable setup time in busy laboratories.
The 630MA is ideal for laboratories that prioritize standardization, reproducibility, and efficiency. Automated normalization reduces manual setup, while four independent chambers allow researchers to perform treatment-control comparisons, concentration-response studies, and drug screening with greater consistency.
The 630MA is widely used in vascular physiology, hypertension, diabetes, endothelial dysfunction, vascular pharmacology, atherosclerosis, drug discovery, and small-vessel research where reproducible, high-throughput experiments are essential.
Both systems feature four independent wire myograph chambers, but the 630MA adds automated normalization, making it ideal for laboratories that require standardized workflows and consistent experimental setup. The 620M uses manual normalization and is well suited for researchers who prefer a traditional wire myography workflow.
The 630MA is the best choice if your laboratory performs routine wire myography, runs multiple users or operators, or needs high-throughput, reproducible vascular function studies. If manual normalization meets your workflow needs, the 620M offers the same four-channel format with a more traditional setup.
