Microinjection – Microdialysis Probe, MI-AZ-X-0Y


*Discontinued Product – Please use the new MI-FZ-X-0Y Probe*

Probe with microinjection cannula, 1 each

Construction is based on AZ-X-Y type probe, but has a microinjection cannula along the outside of the probe shaft.

  • Injection cannula is made of fused silica.
  • Secure connection to the guide cannula.
  • Microdialysis membrane material is artificial cellulose.
  • Molecular weight cut off (MWCO) is 50 kDa.

  • 0.15 mm OD/ 0.075 mm ID for injection cannula.
  • 0.22 mm outer diameter of the membrane.
  • 0.38 mm outer diameter of the shaft which is the needle between body and membrane (microdialysis part only. Size does not include injection cannula).
  • 0.63 mm inlet and outlet needles. Works with most other brands of connectors.
  • Approx. 3 mm diameter (lower) and 2.5 mm (upper) diameter of the body part.
Please specify -X and -Y when you order.

  • “-X” indicates guide cannula length
  • “-Y” indicates membrane length.
  • Injection cannula terminates along side of the middle of the membrane unless you specify otherwise.

Flexible. Custom size probes are available even for low-volume orders.


About Microdialysis Probes


A microdialysis probe has a semi-permeable membrane. Our probes have a 220 µm outer diameter. The probe inlet connects to a syringe pump, which continuously perfuses through the probe. As the perfusate travels through the probe, analytes cross the membrane and travel out the probe outlet into sample vials on a fraction collector or to a sample loop of an analytical system via narrow tubing. This valuable tool enables the sampling of relatively low molecular weight compounds from within the extracellular space of tissues.


In the particular case of the brain and spinal cord, neurotransmitters are released to the extracellular space. This measurement has more meaning as informational transmitting than total tissue content. The collected extracellular fluid is used to determine the chemical composition with sub-nanomolar sensitivity and detect small changes due to manipulation or a physiological/behavioral change. The microdialysis-implanted animals behave close to normal conditions.
