Main Components
The system includes a force measuring bridge amplifier, myograph bath, baseplate, double-walled buffer reservoir, circulating water bath, stimulator, and a workstation with data acquisition software. Its modular design allows for easy assembly and integration.
Operational Features
The IS-05 system is designed for easy setup and maintenance, featuring a water-heated capillary vessel myograph bath for precise temperature control and reduced electromagnetic interference.
Innovations
A new clamping mechanism introduced in 2022 allows for precise sensor positioning and accommodates a wide range of instruments, with a 360-degree adjustable clamp unit.
Conclusion
The IS-05 Small Vessel Myograph system is a significant advancement in vascular research tools, offering reliability and precision for studying microvascular dynamics, suitable for both physiological and pharmacological investigations.
Overview of the ISO-05 Bath and Calibration Kit
The ISO-05 bath is designed for precise calibration with a special kit, featuring a ball-bearing swivel joint for unrestricted movement and accurate results.
Reservoir Design and Functionality
The buffer reservoir is a double-walled chamber with a 250ml capacity, maintaining stable buffer temperature with a water jacketing system, crucial for sensitive substances.
Sensor Fastener and TAP Lid
The sensor fastener allows easy sensor release and secure fixing, while the TAP lid maintains stable experimental conditions by preventing cooling.
Microarteriography Preparation
Preparation involves careful handling of microvessels, requiring patience and experience in microsurgery, with components like a microscope and video camera.
ISO-12 Tissue Bath Preparation
For contraction measurement, the bath is warmed, and the tissue ring is applied onto holders with tungsten wire, with pretension applied after equilibration.
Cleaning and Maintenance
Proper cleaning and maintenance, including washing lines and the bath with distilled water, ensure equipment longevity and reliability.
Experimental Considerations
Maximum active tension is crucial for comparing contractility across vessels, with data on rat arteries providing insights into inner diameter and tension.
Bridge Amplifier in Muscle Experiments
The bridge amplifier enhances weak electrical signals from muscle contractions, interfacing with data systems for accurate measurement and analysis.
SG Bridge Amplifier for Force/Displacement Measurement
This amplifier enhances sensitivity and accuracy in muscle contraction experiments, providing reliable data for understanding muscle physiology.
ISOSYS Software
ISOSYS software excels in data processing and analysis, offering functionalities like easy calibration and automated analysis tools, enhancing efficiency and precision.
