SignaGel® Electrode Gel, 2 oz | ECG, EMG & Defibrillation

Parker SignaGel® Conductive Electrode Gel — 2 oz Tube

SignaGel® Electrode Gel is a highly conductive, multipurpose electrolyte gel. It improves electrical contact between intact skin and compatible electromedical electrodes during ECG/EKG, EMG, biofeedback, and manufacturer-approved defibrillation procedures.

The smooth saline-style formula fills small gaps between the electrode and skin, creating a consistent conductive interface. SignaGel is water-soluble, non-staining, and non-gritty, allowing it to spread evenly and wipe away with a moistened soft cloth after the procedure.

The 15-60 is a compact 60 g / 2 oz tube with a see-through body and a stand-up dispensing cap. It is a practical size for diagnostic rooms, treatment areas, emergency carts, mobile kits, rehabilitation departments, and clinical teaching laboratories.

Quick product specifications

What is SignaGel used for?

ECG, defibrillation, biofeedback, and EMG. Use in any particular workflow remains subject to the electromedical device manufacturer’s instructions. 

How SignaGel supports electrode contact

Human skin is not perfectly flat. Dryness, surface texture, hair, or uneven electrode pressure can leave microscopic air gaps between an electrode and the body.

Because air conducts electricity poorly, these gaps may increase resistance or create inconsistent contact. Conductive gel fills small surface irregularities and creates a more continuous interface.

SignaGel should not be used to compensate for a damaged electrode, broken lead wire, incorrect placement, or incompatible equipment.

Bacteriostatic does not mean sterile

SignaGel is described as bacteriostatic, meaning its formulation is designed to inhibit bacterial growth in the product.

It does not mean that SignaGel:

• Sterilizes the skin

• Disinfects an electrode

• Is appropriate for a sterile field

• May be used on broken skin

• May be used for invasive or percutaneous procedures

• Eliminates the need for infection-control procedures

SignaGel is non-sterile and restricts use to intact, unbroken skin.

SignaGel vs. Spectra 360 vs. Tensive vs. Ten20

Our SignaGel vs. Electrode Gel guide explains how procedure duration, salt content, adhesive requirements, electrode type, and defibrillation compatibility affect product selection. Spectra 360 is positioned as salt- and chloride-free and is not recommended for defibrillation, while Tensive is designed to add temporary adhesive performance. 

SignaGel vs. Spectra 360

SignaGel and Spectra 360 are both electrode gels, but they should not be treated as identical products.

Conductive gel vs. adhesive gel vs. skin preparation

These categories are frequently confused.

SignaGel is not abrasive and is not intended to replace skin preparation. It also does not provide the same electrode-holding function as Tensive or Ten20.

Can SignaGel be used with TENS or NMES?

Many modern TENS and NMES electrodes already contain self-adhering conductive hydrogel. Additional gel is generally unnecessary and may reduce adhesion, make the pad slide, or contaminate its existing gel layer.

SignaGel may be appropriate when:

• The TENS or NMES system uses non-gelled reusable electrodes.

• The equipment manufacturer calls for a conductive saline gel.

• A compatible carbon-rubber electrode requires separate contact media.

• The treating professional has specified SignaGel or an equivalent product.

For reusable non-adhesive options, compare our Uni-Patch Carbon Rubber Electrodes. Their product instructions require compatible conductive media or another approved attachment system.

For longer electrotherapy contact or reusable carbon electrodes, Spectra 360 Electrode Gel may be a more specifically positioned option.

Defibrillation use: an important distinction

Defibrillation is among SignaGel’s recommended applications. That does not mean gel should be added automatically to every defibrillation pad or paddle system.

Modern defibrillation equipment may use the following:

• Pre-gelled disposable pads

• Paddles requiring a specified conductive medium

• Multifunction pacing and defibrillation electrodes

• Proprietary pads that prohibit additional gel

Follow the exact defibrillator or paddle instructions. Do not add SignaGel beneath a pre-gelled adhesive pad unless the equipment manufacturer expressly directs it.

How to use SignaGel

The amount and placement of gel depend on the electrode and electromedical equipment. Always follow the equipment instructions.

1. Confirm compatibility

Verify that the procedure, electrode, and equipment call for a conductive electrode gel. Do not substitute SignaGel when the instructions specify a sterile gel, adhesive paste, ultrasound gel, or another dedicated product.

2. Inspect the skin

Use only on intact, unbroken skin.

Do not apply over:

• Open wounds

• Abrasions

• Burns

• Active rashes

• Infected skin

• Other compromised tissue

3. Check the product

Do not use the tube if:

• The package is damaged.

• The cap or seal is compromised.

• Contamination is visible or suspected.

• The gel has an abnormal appearance or consistency.

• The product is beyond its labeled expiration date.

4. Avoid contaminating the tube

Do not allow the dispensing tip to contact the following:

• The patient

• Staff members

• Used electrodes

• Instruments

• Treatment surfaces

• Contaminated gloves

Dispense the gel without touching the application site.

5. Apply as directed

Use the quantity specified by the equipment or electrode instructions. Apply enough to establish contact without using so much that the electrode moves or gel spreads beyond the intended area.

6. Complete the procedure

Operate the ECG, EMG, biofeedback, defibrillation, or other compatible equipment according to its instructions.

7. Remove the gel

SignaGel is water-soluble and may be removed using a moistened soft cloth.

8. Recap and store

Close the cap after dispensing and protect the tube from direct sunlight.

Frequently asked questions

What is SignaGel?

SignaGel is a multipurpose electrically conductive electrode gel manufactured by Parker Laboratories. It is used to improve contact between intact skin and compatible electromedical electrodes.

What procedures is SignaGel recommended for?

ECG, defibrillation, biofeedback, and EMG. 

Is SignaGel sterile?

No. It is a non-sterile electrode gel.

Is SignaGel bacteriostatic?

Yes. Bacteriostatic means that the formulation helps inhibit bacterial growth in the product. It does not make the product sterile or disinfect the skin.

Is SignaGel water-soluble?

Yes. The manufacturer directs users to remove it with a moistened soft cloth.

Does SignaGel stain?

Parker Laboratories describes it as non-staining.

Is SignaGel gritty?

No. It is described as non-gritty.

Is SignaGel adhesive?

No. It improves conductivity but is not designed primarily to hold an electrode in place.

For conductivity with temporary adhesive hold, compare Tensive Conductive Adhesive Gel.

Can SignaGel be used for ECG or EKG?

Yes, when the ECG electrode or recording system calls for separate conductive gel. Pre-gelled disposable ECG electrodes generally do not require additional gel.

Browse our ECG and EKG monitoring electrodes.

Can it be used for EMG?

Yes. EMG is a manufacturer-listed application.

Can it be used for biofeedback?

Yes. Biofeedback is included in its indications.

Can it be used for defibrillation?

Defibrillation is manufacturer-listed, but the defibrillator or paddle instructions determine whether separate gel is appropriate. Do not add it automatically to pre-gelled defibrillation pads.

Can SignaGel be used with TENS?

Only when the TENS electrode, device instructions, or healthcare professional calls for separate conductive gel. Do not add it routinely to self-adhesive hydrogel pads.

Can it be used with carbon-rubber electrodes?

It may be used when the carbon electrode and stimulation device instructions permit a saline conductive gel. Compare non-gelled carbon rubber electrodes.

Is SignaGel the same as Spectra 360?

No. SignaGel is a multipurpose saline-style electrolyte gel and includes defibrillation among its listed applications. Spectra 360 is salt- and chloride-free, uses a STAY-WET® formulation, and is not recommended for defibrillation. 

Is SignaGel the same as Ten20?

No. SignaGel is a smooth electrode gel. Ten20 Conductive Paste is a thicker adhesive paste used primarily to hold non-gelled neurodiagnostic electrodes.

Is SignaGel the same as NuPrep?

No. NuPrep Skin Prep Gel is mildly abrasive and used to prepare the skin. SignaGel remains at the electrode-to-skin interface during the procedure.

Can SignaGel replace ultrasound gel?

No. Use an acoustic coupling gel recommended for the ultrasound system.

Can it be applied to broken skin?

No. The current IFU limits use to intact, unbroken skin.

Can a patient with a paraben allergy use it?

The manufacturer instructs users not to apply SignaGel to patients with a known history of skin allergies to parabens. 

How should the tube be stored?

Keep it capped and protected from direct sunlight.

What should be done if the tube tip touches the patient?

The IFU warns against allowing the tip to contact patients, staff, or instruments because this may contaminate the remaining gel. Follow the facility’s contamination and disposal policy.
