Electrodes & Wire

• 2mm pin
• 2mm jack socket
• BNC (male, friction fitting to socket)

• Silver wire - replaceable wire; allows minimal fluid in pipette
• Ag-AgCl Pellet - replaceable sintered pellet giving stability & low impedance

• Side or end ports allow application of pressure or suction
• Perfusion ports (some models) allow insertion of fine tubing into the pipette near its tip

EH Series Holders

Ag-AgCl Pellet & Disc Electrodes

Ideal for skin electrodes and other bioelectric recording. The sintered pellet has a pure silver wire embedded for soldering or twisting to other connections.

• E200 - 1.5 mm dia x 3mm long
• E201 - 2 mm dia x 4 mm long
• E210 - 2 mm dia x 2 mm long
• E202 - 4 mm dia x 1 mm thick

• E204 - 12.5 mm dia x 1 mm thick

Ag-AgCl Pellet & Wire Electrodes

Two pellet electrodes embedded on a .25 x 70 mm silver wire, and a wire electrode in which the last 10 mm of the wire is uniformly coated with Ag-AgCl to a maximum diameter of 0.8 mm.

• E205 - pellet 1 mm diameter on 70 mm x 0.25 mm wire
• E206 - pellet 2 mm diameter on 70 mm x 0.25 mm wire
• E255 - coating 0.8 mm diameter on 70 mm x 0.25 mm wire

Flat-tip Ag-AgCl probes

Sintered Ag-AgCl cylinders encased in a sturdy epoxy tube and fitted with a 2mm tinned copper wire. The flat end of the electrode can be resurfaced with fine abrasive. Ideal for use as a reference electrode in bath solutions.

• E207 - tip 2 mm dia x 4 mm thick; tube 3.5 mm dia x 25 mm long
• E208 - tip 2 mm dia x 4 mm thick; tube 5 mm dia x 50 mm long

Disc Electrodes

Encapsulated disc electrodes leaving only the electrode surface and edge exposed - the 20 cm connection wire is protected. Ideal for skin electrodes.

• E242 - disc electrode 4 mm diameter
• E243 - disc electrode 8 mm diameter
• E244 - disc electrode 12.5 mm diameter
