EL451 (Ndl electr. Concentric 30 mm TP.)

EL452 (Ndl electrode Unipolar 15 mm TP.)

EL450 (Ndl electrode Unipolar 37 mm TP.)

Use needle electrodes for stimulation or recording in animal subjects and tissue preparations. These 28-gauge stainless steel needle electrodes are equipped with a flexible lead terminating in standard Touchproof connectors.

Use one EL451 electrode, plus one EL452 ground electrode, when recording from a single site (e.g. studies of individual muscle fibers).

Use a pair of EL450 or EL452 electrodes, plus one EL452 ground electrode, for general-purpose recording (e.g. ECG).

For stimulation, use a pair of EL450 or EL452 electrodes.

Teflon coated needle electrodes are fully insulated, with a clear Teflon overcoat, except for the conductive needle tip. Needle electrodes are shipped non-sterile, so pre-sterilization is required.
