EXT-T2 – Extracellular Amplifier for Tetrodes

Advantages of the EXT-T2

• User-friendly amplifier for tetrode recordings
• Prevents unintentional alterations in filter or gain settings
• Cost-effective solution by utilizing custom-made tetrodes
• Also offered with compact headstages for in vivo recording

Dual Tetrode Amplifier

Extracellular recording using 4-channel tetrodes is increasingly gaining popularity. The EXT-T2 amplifier/filter is specifically engineered for recording from a maximum of two tetrodes. The signals captured from each individual tetrode connected to the headstages are amplified, filtered, and routed to the BNC connectors located on the front panel. Each OUTPUT is accessible via two BNC connectors. Measurements are conducted in a single-ended configuration relative to GND, with filters and gain settings adjustable internally.

Tetrode amplifiers are also available with compact headstages for in vivo studies involving freely moving animals.
