  • Injection cannula (0.075/0.15 mm ID/OD) outside the membrane.

  • Position of injection cannula tip specified by the customer. Standard is in the middle of the membrane because it works better to monitor the effect of injection than if positioned at the membrane tip.

  • Guide cannula OD is 0.7 mm.

  • Refer to the FX probe for X and Y specifications.

  Please specify probe dimensions upon ordering. All probes are tailor-made.
  X for shaft length and Y for membrane length. X = 1 to 20 mm, Y = 0.5 to 4 mm

Variety of Sizes Available for AtmosLM™ Microdialysis Probes

We carry standard sizes of 4, 8, or 12 mm for the shaft length (X mm) and 1, 2, 3, or 4 mm for the membrane length (Y mm). Other sizes are available.​

To collect the sample from the probe, a “pull” pump is required in addition to the infusion syringe pump. Eicom has developed a new peristaltic pump, the ERP-10, specifically for the AtmosLM™ system. The ERP-10 completes the AtmosLM™ system offered by Eicom, an incredibly convenient large molecule sampling system. 

Membrane material polyethylene. 0.44 mm OD.
Shaft: 0.58 mm OD/0.5 mm ID
