The design of microdialysis probes typically falls into two basic categories, linear and pin (or “concentric”). Pin style probes have a membrane located at the distal end of a supporting cannula. They are most often used for brain microdialysis, though can also be used for vascular and other implants. The linear style probe is a membrane imbedded within a length of small diameter tubing. It is usually used for other tissue implants including subcutaneous, dermal, adipose, muscle, intraperitoneal, liver, lung, etc. When you use BASi® brain microdialysis probes and guides, you will need a Probe Clamp to fit to your existing stereotaxic frame.
