Feature 1

Smooth” and “secure” attachment of probe and guide cannula

Feature 2

Improve probe desorption errors during sampling

Protrusions on the sides of the probe allow for a tighter fit.
Probe has zero Zero desorption error (0/50 cases, our data)

Feature 3

Polyarylethersulfone (PAES) dialysis membrane

We provide stable data with high return rates.
