Introduction
Designed for chronic experiments, the Microprobes Microwire Arrays MWA provides the optimum in flexibility and affordable alternative for the neuroscience community.
Applications
- Up to 32 penetrating wires per array for short- and long-term recordings.
- Custom wire length (5-23 mm), including different length for each row.
- Custom spacing between wires is in the range of 250 - 1000 µm.
- Custom wire diameter options available (25/50 µm).
- Custom impedance for individual wires between 200-800 kΩ.
- Stainless steel and Platinum/Iridium fine wires with teflon or polyimide insulation material.
- Custom reference and ground electrodes according to the researcher’s requirements.
- Optionally integrated fiber optic and/or drug delivery cannula.
