Neural Probes · A-Series (Polytrode & Tetrode)
Single-Shank 16-Channel Probe, 8 mm
Sites clustered rather than spread — polytrode and tetrode groups a sorter can separate
A single long 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: 16 sites (a common choice — 84 of 369), 8 mm shanks (67th percentile of the 366 measured), a 1.16 mm-deep site array (58th percentile), 212 sites/mm² (47th percentile) and a 0.47 mm³ neural interface (28th percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, spaced for a laminar profile. The long shank reaches deep targets.
Orders as a probe-plus-package assembly, in 7 package configurations. Silicon 15 or 50 µm thick. Z-coat available. Optical stimulation runs from a separate laser or LED source. Research use only.
