MBR-4-10 Brain Microdialysis Probe: 4mm membrane, 10mm cannula (when used with guide)


Product number     QVMD2234

  • The "MBR" style microdialysis probe is primarily intended for use for mouse brain microdialysis or adjacent multiple rat brain implants.
  • Concentric-style microdialysis probe.
  • Standard membrane lengths: 1mm, 2mm and 4mm.
  • Probe membrane is polyacrylonitrile (PAN) with an OD of 320µm.
  • The cannula length is optimized to reach anywhere in the rat brain.
  • Custom membrane and cannula lengths are available.


  • MBR 5 microdialysis probes are small and lightweight to accommodate a fragile mouse skull. They can reach anywhere in a mouse brain or can be used for dorsal rat brain sampling. Use with MBR-5 Guide Cannulae.
  • MBR 10 microdialysis probes are suitable for ventral implants in rats or for multiple implant sites. Use with MBR-10 Guide Cannulae.
  • MBR microdialysis probes can be implanted as close as 2.5 mm on center without a guide, or 3.2 mm on center with a guide. The probes have elongated inlet/outlet tubing to keep fingers further away from fast, sharp mouse teeth when connecting tubing.
  • Cannula: Coated fused silica
  • Probe Volume:
    • MBR1-5: 7.9 µL (due to user protective elongated I/O tubing - see use)
    • MBR 2-5: 8.0 µL (due to user protective elongated I/O tubing - see use)
    • MBR 2-10: 3.5 µL
    • MBR 4-10: 3.6 µL
  • Membrane: Cellulosic. 35 KDa MWCO, 220 µm OD
  • Membrane: OD 22 µm, ID 180 µm
  • Cannula Diameter: OD 350 µm
  • Cannula length when in guide: 5 or 10 mm
  • Cannula length without guide: 7 or 12 mm
  • Head Diameter: OD 3.2 mm
  • Tubing Inlet/Outlet and Height:OD 635 µm
    • MBR x-5 probes: ~5 cm tall
    • MBR x-10 probes: ~2 cm tall
