Neural Probes · A-Series (Polytrode & Tetrode)
Single-Shank 32-Channel Probe, 3 mm
Sites clustered rather than spread — polytrode and tetrode groups a sorter can separate
A single short shank with sites staggered in two columns so neighbouring sites see the same units. Among the 371 probe designs in the design space it is mid-range: 32 sites (a common choice — 155 of 369), 3 mm shanks (a common choice — 37 of 363), a 1.58 mm-deep site array (77th percentile), 179 sites/mm² (45th percentile) and a 0.64 mm³ neural interface (49th percentile).
Large sites read a wider patch at lower impedance, suited to field potentials and multi-unit activity, spaced for a laminar profile. The short shank suits superficial targets.
Orders as a probe-plus-package assembly, in 2 package configurations. Silicon 15 µm thick. Z-coat available. Research use only.
