Perivascular and Tubing Flow meters

 

 

 

 

Simplicity, Versatility,

and Accuracy

 

Patented in 1983, Transonic Systems' innovative ultrasonic transit-time technology has been the gold standard for volume flow measurement for more than two decades. Measurements with Transonic flowmeters have been independently validated in many applications and referenced in over 3,000 publications including more than 600 publications involving rats and mice.

TS 420 Perivascular Module

Transonic Systems' hallmark simple plug & play TS420 Flow Modules offer an unmatched range of precision flowprobes for vessels 0.25 mm and larger; a spectrum of applications including cardiac output and cardiovascular dynamics, renal hypertension, carotid thrombosis and stroke models, hemorrhagic shock, ischemia/reperfusion, portal hypertension, and hindlimb studies. - Accurately measures volume flow of less than 1 ml/min - Expanded ultrasonic frequency range for the smallest flowprobes imaginable! Implantable 0.5 mm and 0.7 mm mouse probes. - 160 Hz bandwidth to accurately characterize flow dynamics at high mouse heart rates - Analog meter displays voltage proportional to flow. - Easy access front panel receptable for chronic probe calibration keys

 

 

Transit Time Perivascular Probes

Transonic Systems probes for microcirculation with Transonic flowmeters produce repeatable high resolution volumetric blood flow measurements on vessels as small as 250 micron diameter, but also in vessels as large as 1000 microns.. Choosing the appropriate series, size and style probe for your application will enhance the absolute accuracy of the flow measurement.

Big size probes available for vessels up to 20 mm.

 

 

Perivascular Probe selection Code = MA XX Y

Where instead of XX you have to insert the desired probe size in steps starting from 0,25 mm diameter up to 20 mm. Instead of Y you have to insert the selectedcable exit type where B = Back or S = side (lateral)

 

Probes can then present different types of reflectors and closing systems around the vessels. Easier to let us know the purpose of your experiment (vessel to be measured, animal used, weight of the animal, etc. and we will provide a list of suitable probes among them you can select the most appropriate ones.

Langendorff Modular Systems

Isolated Heart Perfusion

 

The Langendorff Isolated Heart Perfusion Systems permits the researcher to create constant flow or constant Pressure or WORKING HEART Langendorff preparations. The system may be placed or spontaneously beating. The system can be instrumented to measure left ventricular pressure, apical force using the built-in pulley system and coronary resistance, as well as surface fluorescence, luminescence and absorption.

This type of system is often used for dose response studies in pharmacology. Its compact design has been used to introduce the heart into NMR chambers or other restricted areas. The heart chamber, components, and perfusate lines are water-jacketed for temperature control.

The system is color coded for easy assembly and features charts with basic protocols and instructions.

Recommended when measurements of actual cardiac work or cardiac efficiency are necessary, such as in metabolic or transgenic studies.

DMT Myograph Systems

 

DMT A/S develops and produces equipments for customers with the field of cardiovascular research in both the public and private sector. The equipment is used primarily for pharmacological and physiological studies of arteries and veins. Danish Myo Technology A/S (former J.P. Trading) is a medical- and biotechnology company with more than twenty years of experience in the development and manufacture of myograph equipment designed for the in vitro assessment of vascular structure and function. Historically, myography development closely mirrors the scientific discoveries of the 1980s and 1990s when the basic mechanisms underlying the development of vascular changes in hypertension, diabetes and atherosclerosis were elucidated. Basing our designs and techniques on the methodologies of Professor M. J. Mulvany (Inst. of Pharmacology, University of Aarhus, Denmark), we have integrated the needs of the user with first class mechanical, electronical and software engineering to become one of the worlds leading designers and manufactures of wire, pressure and perfusion myographs. - Examination of small Vessel/Arteries with diameters ranging from 60 micron to around 3 mm.

Pressure Myograph for Rapid Freezing - 115FP

 

This pressure myograph chamber is designed for biochemical or morphological studies where rapid freezing of the vessel is frequently required. This chamber is ideal for rapid freezing of a cannulated and pressurized vessel for biochemical studies, or for quick transfer from a physiological solution into a fixative for morphological studies. The experimental chamber is made of stainless steel. A window at the base of the chamber allows the vessel dimensions to be digitized for analysis of diameter etc. The adjoining chamber, which is removable, is used for freezing or adding other fixing solutions. By raising the segment holder and thus the vessel and its tubing, the chamber stage can be moved to the side, for rapid or instant freezing or removing of the vessel segment for later analysis. This process can be done in less than a second. This chamber can be obtained as a complete setup - similiar the 110P, or as an add-on to the 110P

Transducers continuously monitoring inflow and outflow pressures and longitudinal tension to allow standardization of arterial length using micrometer. Intravascular pressures controlled by an easily adjustable turret with optional servo control. A heating system gives electronic feedback for maintaining organ chamber temperature above ambient temperature. The chamber cover includes ports for superfusion, for rapid draining and filling, and for gas supply. All measurements are continuously recorded by the computer.
