1294A Biological Impedance Interface
Electrical bio-impedance is a well-proven, powerful technique for analyzing a wide range of ionic and charge transfer processes in bio-materials.
Until now, the use of impedance in bio-material applications has been limited by a number of factors, such as the ability to measure accurately the very low currents involved, and the need for safe working when performing experiments on living tissue.
The 1294A Impedance Interface has been designed specifically to overcome these difficulties, and to meet the present and future needs of bio-material researchers everywhere.
Used in conjunction with Solartron's 1260A or 1255 Frequency Response Analyzers, the 1294A's advanced measurement technology offers:
-
Improved Accuracy
- True differential 4-terminal connections minimise the effects of localised disturbances at the current injection points
- Balanced generator
- Driven shields
-
Safety Compliant
- IEC 601 connections - for in-vivo investigations into a wide range of applications including cosmetics, skin hydration, tissue impedance and tooth decay
-
Wide Measurement Range
- 1µV, 1pA sensitivity
- Up to 1MHz frequency range
- Impedance range 10-3 to >1011W (>100GW) to cover virtually all bio-materials
-
Temperature Control
- 1294 system interfaces with standard temperature controllers
-
Applications
- Ischemia in tissue, e.g. during organ transplants
- Detection and study of tumor tissue and the effects of temperature on tumor growth
- Investigation of body fats
- Dental research
- Gel/electrode studies
- Dermatological studies
- Blood cell analysis, viral infections
- Fruit and food freshness
- Growth of plants and trees
