Electrode Gel

Bulk and private label electrode gel. Engineered with balanced chloride electrolytes to bridge epidermal air gaps and maintain < 20 Ohm impedance for ECG, EEG, and reusable TENS hardware.

This electrode gel acts as a fluid interface specifically formulated for passive surface electrodes, such as stainless steel ECG clamps, EEG cap sensors, or carbon rubber TENS pads. In clinical diagnostics, microscopic air gaps between dry skin and rigid hardware block electrical current and bio-signal transmission. This medium fills those physical voids. It connects the epidermis to the metal substrate via a high-ion-concentration fluid network. We supply this liquid formulation in bulk and OEM packaging for B2B medical consumable distributors and device manufacturers.

• Epidermal Air Gap Bridging 

  Pressing a flat metal electrode directly against the skin leaves air pockets due to the rough micro-topology of the stratum corneum. Since air is an insulator, the equipment's output impedance spikes into the thousands of ohms. The high flowability of the gel allows it to seep into these microscopic epidermal fissures. Dissociated chloride ions establish a continuous, low-resistance (< 20 Ohms) charge transfer path directly between the horny layer and the metal substrate. 

   

• H3: Hardware Oxidation Threshold 

  Excessive salt concentrations yield excellent conductivity but inevitably corrode reusable medical-grade stainless steel clamps or Ag/AgCl probes. Metals exposed to heavy chlorides undergo rapid pitting. Our electrolyte titration process restricts the salt density to a specific threshold. This formulation delivers the sensitivity required for millivolt-level bio-signals (like ECG) while delaying the electrochemical degradation of expensive diagnostic hardware. 

   

• H3: Evaporative Resistance 

  Clinical environments are often extremely dry due to constant HVAC airflow. A pure water-based gel begins to evaporate at body temperature within 15 minutes, leaving behind a non-conductive salt crust. A specific ratio of humectants blended into the formula lowers the moisture vapor evaporation rate of the matrix. This allows the gel to maintain its liquid volume and viscosity during continuous 60-minute dynamic monitoring sessions, such as treadmill stress tests.

• Packaging Configurations : Available in 15ml to 250ml squeeze tubes, 250g cylindrical bottles, and 5L bulk flexible bladders for high-volume clinic dispensers. Tube exteriors accommodate 4-color offset printing. 

• Supply Chain Routing: Chemical compounding and primary vessel filling run in China. Batch consolidation, secondary packaging, and final palletization are processed through our Vietnam facility to build supply chain resilience and optimize regional logistics routing.

Systems : Liquid formulation and filling lines operate strictly within ISO 13485:2016 frameworks. 

Compliance : Supported by safety data sheets (SDS) and non-cytotoxic testing documentation.

B2B procurement channels can request formulation safety data sheets and physical bottle samples.
