Brain “BR Style” Guide Cannulae
These guide cannulae fit BASi’s most popular “BR” style brain microdialysis probes. There are two version of this guide; they differ in how they secure the probe or stylete in the guide. One uses a rubber O-ring that lightly snaps into the notch in the probe or stylete head when inserted. Removal is equally simple. The other uses an Ω (Omega) ring that can be turned to open the ring’s “window” to allow insertion of a probe or stylete. When the omega ring is turned further, closing the window, the probe/stylete is locked securely in place. Removal is equally simple. If you are working with mice, see the MBR style guides.

| Part Number | MD-2250, O-ring MD-2251, Omega-ring
|
|
| Cannula | Inert, biocompatible plastic
|
|
| Stylet | Stainless Steel
|
|
| Cannula Length | 10 mm. This length permits you to reach even the deepest rat brain target. The length is optimized so that when a ”BR” style microdialysis probe is inserted, only the probe membrane protrudes out. Custom length guides available
|
|
| Use | Provides pre-experiment surgical targeting when microdialysis sampling from awake animals. Permits insertion of probes following surgical recovery. Facilitates post-experiment microdialysis probe removal and potential probe reuse. For use with BR, IBR, Infusion, and custom BR microdialysis probes. O-ring is non-metallic, can be used for NMR imaging.
