Ten20 and Elefix V both serve as conductive pastes for recording electrodes, but the names alone do not establish that they are interchangeable. Compare the exact formulation, labeled application, electrode requirements, and evidence before changing your department's paste.
Our Ten20 conductive paste listing provides the current jar options we supply. We include Nihon Kohden's Elefix V here as a comparison product, not as a claim that we stock it or have tested the two pastes side by side.
This guide compares published documentation and research. It is not a clinical substitution authorization, an application protocol, or a guarantee of recording performance. Follow the instructions supplied with the exact paste, electrodes, and recording system.

Common questions
Ten20 vs. Elefix V at a glance
Start with the product's identity and intended use. A broad description such as “EEG paste” is not enough to identify the formulation or confirm suitability for every sensor.
Scroll sideways to read all comparison columns.
| Comparison point | Ten20 | Elefix V |
|---|---|---|
| Manufacturer | Weaver and Company | Nihon Kohden |
| Recording applications | Non-gelled neurodiagnostic electrodes; listed examples include EEG, evoked potentials, polysomnography, and multiple sleep latency testing. | The U.S. clearance describes surface-electrode use for EEG and EMG. |
| Published handling description | Weaver describes an adhesive, conductive paste with washable, non-drying characteristics. | Nihon Kohden documents greater stiffness and temperature resistance relative to its earlier Elefix formulation. |
| Examples of formats | Jars, tubes, and single-use cups; our product listing offers jar packs. | 400 g jars and 180 g tubes in the manufacturer's regional catalog. |
| Identity to check | Weaver product reference, container size, and units per pack. | The word V, the ZV product reference, and the package instructions do not assume older Elefix documentation applies unchanged. |
The handling descriptions are supplier statements, not results from a shared test. Neither “non-drying” nor “improved adhesion” establishes how two different products compare over your intended recording period.
Elefix and Elefix V are not the same comparison reference.
The FDA-filed Elefix V submission, cleared in 2020 as K191975, compares Elefix V with the earlier Elefix EEG Electrode Cream. It describes formulation changes intended to increase stiffness and temperature resistance and bring the pH closer to neutral.
That comparison is not Elefix V versus Ten20. A claim that a product improved over its predecessor cannot establish that it outperforms a different manufacturer's paste.
When reviewing an older paper, product review, or purchasing record, check whether “Elefix” identifies the exact product. A recent publication date alone does not resolve a missing model or formulation reference.
What does the comparative research actually show?
Published comparisons exist, but their methods and product descriptions matter. The studies below should not be presented as a definitive clinical ranking of the current Ten20 and Elefix V products.
Scroll sideways to read the findings and limitations together.
| Published comparison | What was reported | What it does not establish |
|---|---|---|
| 2011 neurotelemetry electrode-application study | Four methods combined Ten20 or Elefix with different fixation approaches. Collodion with Ten20 required the longest initial hookup but had the fewest patients needing electrode repair. | Results describe paste-and-fixation combinations. The study also predates the 2020 Elefix V clearance, so it is not a direct comparison with current Elefix V. |
| 2024 EEG artifact and satisfaction comparison | Among 86 analyzed recordings, artifact and noise differences were not statistically significant. Survey ratings favored Elefix for satisfaction and perceived adhesion. | The authors noted that prior familiarity with Elefix may influence preferences. The paper names Elefix without clearly identifying Elefix V; a nonsignificant result is not proof of equivalence. |
Our reading is that a defensible comparison needs both the exact product and the complete recording setup. Record quality, electrode maintenance, handling preference, and skin tolerance are separate outcomes. A favorable result in one does not automatically settle the others.
For a purchasing decision, ask which outcome the proposed change is intended to improve. “We prefer how it handles” is different from “we documented fewer interruptions during the same type of study.” Neither should be substituted for a patient-safety assessment.
Compare labeling and skin precautions before handling claims.
Do not infer “safe for every sensitive scalp” from a pH description, a familiar brand, or the fact that a paste is widely used. Weaver's Ten20 instructions warn about skin allergy and sensitivity. Nihon Kohden's Elefix V safety information also warns about skin reactions.
Both documents restrict application to appropriate intact skin and require action if irritation develops. Use the current instructions and the department's monitoring process; this comparison does not establish which paste is less irritating for an individual patient.
When changing brands, obtain the current instructions for use and any ingredient information needed for a known sensitivity. Review the paste together with the electrode, preparation product, fixation materials, and removal process. Do not make a clinical substitution solely because both containers say “conductive.”
For detailed Ten20 ownership questions, use our Ten20 and NuPrep storage and cleanup guide. Do not transfer its product-specific instructions to Elefix V.
Match the exact package before comparing a quote.
Ten20 and Elefix V are offered in different container sizes. Compare the actual supplier quote with the manufacturer reference, rather than assuming “one pack” means the same quantity.
Scroll sideways to compare container and order quantities.
| Product | Reference | Package contents | Labeled total |
|---|---|---|---|
| Ten20 4 oz jars | 10-20-4 | 3 × 114 g jars | 342 g |
| Ten20 8 oz jars | 10-20-8 | 3 × 228 g jars | 684 g |
| Elefix V jars | ZV-401E03 | 3 × 400 g jars | 1,200 g |
| Elefix V tubes | ZV-181E10 | 10 × 180 g tubes | 1,800 g |
Totals are calculated from the labeled container quantities. Elefix V examples are from Nihon Kohden's European catalog; confirm the applicable selling unit and reference with your supplier. This is not a complete global catalog or a statement of our Elefix V availability.
For current Ten20 ordering options, use our Ten20 product page. Our Ten20 package-size and cost guide explains unit-cost calculations without repeating them here.
A lower cost per gram is only one consideration. If a proposed change affects how much is dispensed, discarded, or used during electrode maintenance, keep those observations separate from the quoted purchase price. This guide does not assign a universal number of studies per container.
Before switching, define what your department needs to verify
Use the following as a purchasing-review worksheet, not as instructions to experiment on patients. Any clinical evaluation should be authorized and supervised through the department's normal process, with the applicable product and equipment instructions followed.
| Decision | What to document | Avoid assuming |
|---|---|---|
| Is the candidate approved for this setup? | Exact paste version, electrode type, procedure, local labeling, and the person authorizing a change. | All EEG pastes are automatic substitutes. |
| What problem are we trying to address? | A specific concern such as handling, electrode maintenance, or purchasing availability. | A different paste will solve every signal problem. |
| Which recording observations matter? | The department's accepted contact-quality checks, interruptions, and maintenance events for the intended procedure. | Initial adhesion predicts the entire recording. |
| How will safety and removal be reviewed? | Applicable skin monitoring, reported reactions, removal instructions, and electrode-care requirements. | A stronger hold or familiar texture means better skin tolerance. |
| Can the order be repeated accurately? | Supplier reference, container and pack size, lot information, expiration, and approved alternatives. | The next similarly named listing contains the same product. |
Set the acceptance criteria before deciding to change the department's standard supply. Record limitations as well as favorable observations. A purchasing comparison should make an approval easier to explain, not turn an informal preference into an unsupported clinical claim.
For broader inventory planning, our EEG and sleep-lab electrode supply checklist covers the rest of the supply order. For replacing paste in an established neurofeedback setup, use our Ten20 neurofeedback reordering guide.
Common Ten20 and Elefix V comparison questions
Can Ten20 replace Elefix V for EEG?
It can be considered as a candidate where its labeled use and the recording system's instructions fit the intended application. That is not an automatic substitution approval. Confirm the exact electrodes, procedure, and department requirements before changing an established supply.
Which paste holds better during an overnight recording?
The research summarized above does not establish a universal winner for current Elefix V versus Ten20. Check which formulation, fixation method, recording duration, and maintenance outcome a claim actually describes. Do not transfer a short laboratory comparison or an older application study to every overnight protocol.
Does either paste replace NuPrep?
NuPrep is a skin-preparation product, not simply another name for Ten20. Our Ten20 vs. NuPrep comparison explains that separate product-role question. Follow the system's instructions rather than swapping products because both are used around electrodes.
Can I use these pastes with TENS, NMES, or other stimulating electrodes?
Ten20's instructions exclude current-inducing electrodes. For Elefix V, the U.S. clearance identifies EEG/EMG recording applications, while a regional safety-information extract also mentions stimulation. Those documents should not be treated as identical labeling. Confirm the current local instructions and the exact stimulating system with the responsible clinician or supplier; this guide does not authorize that use.
Should I change paste immediately when a recording is noisy?
Not solely on that observation. Ask the responsible technologist to assess the recording setup using the system's troubleshooting process. Replacing paste is a product decision, not a substitute for finding the source of a signal problem.
Compare the documented use, then confirm the purchase.
Identify the exact product, separate published evidence from marketing descriptions, and confirm the required application before comparing the final order. An approved, clearly documented choice is more useful than an unsupported “best EEG paste” label.
