We at Leonhard Lang have long been believers that user concerns and ideas for improvement are as important to us as producing high quality performing electrodes. Many of the changes we make come from suggestions that you, the user, raise. All SKINTACT® electrodes offer:

  • easy to tear open pouches which can be folded over after use

  • quick and easy stripping away of electrodes from the backing liner

  • non-adhesive tabs making removal of electrodes quick and comfortable also for the patient


In order to achieve high quailty results even during the most demanding ECG procedures an electrode made of impermeable materials with enhanced adhesive is needed. These might strain the skin, though. Avoiding skin trauma, SKINTACT® electrodes are designed and manufactured using only proven biocompatible materials that provide the quality you expect, yet are kind to the patient’s skin. 


Ag/AgCl Sensor


Carbon Contact Interface


Direct Cable Contact to stud


The choice of sensors is critical to the performance of an electrode. SKINTACT® electrodes only incorporate sensor systems of superior electrical properties and contact quality. In SKINTACT® standard snap electrodes only the highest quality durable stainless steel studs are used. They are machined to tolerances, which create minimum wear on your lead wires. All eyelets have an Ag/AgCl layer. With C-LINE technology AgCl is only placed at the interface to the gel in Aqua-Wet and Aqua-Set electrodes to prevent corrosive effects and to maintain undiminished quality for the duration of the shelf life.


As the requirements for short term procedures are so different to the ones needed for long term monitoring Leonhard Lang has developed a range of conductive mediums specific to these applications. Our gels have excellent pick up capabilities and provide reliable quality recordings with minimal skin reactions to the patient.

A liquid gel designed for fast pick up of the ECG signal even if inadequate skin prep is carried out. Aqua-Wet electrodes are an ideal choice for short term procedures. They give dependable quick tracing with easy application and removal.


The next generation in hydrogel electrodes. Aqua-Tac electrodes are fast becoming the choice in long and short term procedures. Our solid adhesive Aqua-Tac offers the best of both worlds i.e. quick pick up even if inadequate skin prep is carried out and provides consistently high quality recordings for long term monitoring with minimal skin reactions.
Aqua-Tac also gives the added benefit of 100% skin surface contact.


A solid wet gel designed for long term monitoring and stress testing. Aqua–Set electrodes offer longer lasting performance. They are less prone to gel dry out and can be pressed in the centre without the risk of gel spreading onto the adhesive. Due to the solid wet gel formulation these electrodes are an ideal choice for long term monitoring. Its semi-solid nature also helps reduce motion artefacts. Our specially formulated conductive medium has excellent electrical response and due to its aqueous nature provides a quick reduction of skin impedance producing excellent quality recordings and stable baselines. 


There is a combination of SKINTACT® adhesives and backings to meet the requirements of every major application. Versatile SKINTACT® electrodes are available with four backings:
Demanding applications such as anaesthesia, emergency care and stress tests put electrode stability and reliability to the test. Foam backing materials protect sensor and gel from surgical and cleaning fluids. The thin foam layer permits maximum flexibility. Skin-friendly microporous tape adapts well to body contours, increasing comfort. Microporous-tape-backed SKINTACT® electrodes promote breathability and transpiration, important in long term applications.
Soft cloth backing offers many of the benefits of tape plus added elasticity to conform to most body movements. Cloth-backed SKINTACT® electrodes provide the long term comfort and durability required by active patients.
Clear tape backing combines sensor area protection against fluids and some breathability through its perforation. In addition, being transparent it permits constant skin observation.

Packaging materials

Water contents in a gel is crucial for its electrical and – in case of hydrogels – its adhesive performance. In order to ensure that our products reach you in the freshest possible state and keep their superior performance quality for all their shelflife SKINTACT® electrodes are packed immediately after they are produced into steamproof aluminium pouches.

Performance and safety

Performance and safety of all SKINTACT® electrodes and other ECG products have been designed and stringently tested according to all applicable standards. All SKINTACT® ECG electrodes meet ANSI/AAMI EC12 on disposable ECG electrodes, ISO 10993 on biocompatibility and the European Medical Device Directive.
