The FEP and PEEK Tubing for CMA Probes is used in microdialysis experiments to collect extracellular fluid samples from the brain or peripheral tissue in freely moving or anesthetized animals, enabling real-time monitoring of neurotransmitters and drug concentrations.

The FEP and PEEK Tubing for CMA Probes is compatible with standard rodent models including rats and mice. Accessories are available in multiple configurations to match different stereotaxic targets and animal sizes.

The tubing integrates directly with CMA micro infusion pumps, fraction collectors, and probe assemblies. Connections use low dead-volume adapters to minimize sample dilution and ensure accurate analyte recovery.

Using the tubing with an analytical system such as HPLC or LC-MS, researchers can measure dopamine, serotonin, glutamate, GABA, acetylcholine, and various neuropeptides in the extracellular space.

FEP (fluorinated ethylene propylene) tubing offers excellent chemical inertness and flexibility, making it ideal for routine microdialysis sampling. PEEK (polyetheretherketone) tubing provides superior rigidity and ultra-low analyte adsorption, making it the preferred choice for peptides, lipids, and other compounds that tend to bind to conventional tubing materials. The choice depends on the analyte chemistry and the analytical method used downstream.
