A three-pack of Ten20 can contain 342 g or 684 g of paste, depending on the jar size. The useful comparison is the amount in the whole order, the number of containers you need, and how much your department will use before disposal is required.
We offer Ten20 Conductive Paste in three-jar packs of 4 oz or 8 oz jars. This guide compares those packs with the manufacturer's tube and single-use formats, then shows how to evaluate price without confusing a jar, a pack, or a patient-use quantity.
This is a purchasing guide for compatible neurodiagnostic workflows, not an application protocol or a measured product-yield study. Follow the current product instructions and your facility's procedures.

Ten20-package sizes: jars, tubes, and single-use cups
Weaver's Ten20 sales sheet identifies four package formats. The totals below are calculated from the labeled net quantity, not the weight of the shipping carton.
Scroll sideways on smaller screens to compare all package details.
| Format | Weaver reference | Contents of one package | Total labeled paste |
|---|---|---|---|
| 4 oz / 114 g jars | 10-20-4 | 3 jars | 12 oz / 342 g |
| 8 oz / 228 g jars | 10-20-8 | 3 jars | 24 oz / 684 g |
| 4 oz / 114 g tubes | 10-20-4T | 3 tubes | 12 oz / 342 g |
| 15 g single-use cups | 10-20-1 | 24 cups | 360 g |
Jar and tube weights follow the manufacturer's labeled ounce/gram equivalents. The cup quantity is documented in Weaver's price list effective January 1, 2025; that document is used here to identify the format, not as a current price quote. Our linked product listing offers the two jar formats; do not assume the other formats are stocked by us.
The letter T matters: 10-20-4 is the 4 oz jar, while 10-20-4T is the 4 oz tube. The matching quantity of paste does not make the containers interchangeable for ordering or dispensing.
What does a Ten20 three-pack cost?
The selected 10-20-4 option was $29.95 for three 4 oz jars, before applicable tax. Use the selected option's current price when ordering; do not apply a displayed starting price to every size.
| Purchasing measure | Calculated amount |
|---|---|
| Whole three-jar pack | $29.95 |
| Per jar: $29.95 ÷ 3 | About $9.98 |
| Per labeled ounce: $29.95 ÷ 12 | About $2.50 |
| Per 100 g: $29.95 ÷ 342 × 100 | About $8.76 |
Amounts are rounded only after calculation. Per-jar figures describe the pack's arithmetic; they are not an offer to buy individual jars at that price.
We offer free standard U.S. shipping with no minimum order. For any supplier comparison, include the delivery service you actually need and apply the same tax treatment to both offers.
Delivered cost per 100 g = delivered order cost ÷ total labeled grams purchased × 100.
Delivered order cost includes the merchandise after discounts, shipping, and required fees. Either include applicable tax in both quotes or identify both as before-tax comparisons.
4 oz vs. 8 oz: compare equal amounts of paste
One 8 oz three-pack contains the same labeled amount of paste as two 4 oz three-packs. That creates a useful comparison: three larger jars versus six smaller jars, with 684 g in either purchase.
| Compare | Two 4 oz jar packs | One 8 oz jar pack |
|---|---|---|
| Total jars | 6 jars of 114 g | 3 jars of 228 g |
| Total paste | 684 g / 24 labeled oz | 684 g / 24 labeled oz |
| Price to compare | $59.90 at two unchanged $29.95 pack prices | Confirm the current selected 8 oz pack price. |
| Practical difference | More individual containers for separate stations or staged opening | More paste in each container; fewer jars for the same total mass |
The break-even rule
An 8 oz three-pack has a lower purchase cost per gram when it costs less than twice the 4 oz three-pack.
Using the dated $29.95 example, the threshold is $59.90. A lower 8 oz pack price wins on purchased quantity; the same price ties. Recalculate when discounts, shipping, or tax treatment differ.
This is a price threshold, not a quoted 8 oz price. It also assumes that the paste being compared remains available for use. It does not prove that the larger-container option will be more economical in your department.
For example, six stations each requiring their own original container create a different purchasing need from one busy station. A single 8 oz three-pack supplies only three original containers, even though it holds the same paste mass as six 4 oz jars. Do not assume that transferring paste into unapproved containers is an acceptable way to make up the difference.
Choose the dispensing format before chasing the lowest unit price.
Jars: match the container to where it will be opened.
Compare consumption at the specific cart, room, or service using the jar. A large hospital can still have a low-volume station. Smaller jars may suit several locations or staged openings; larger jars may suit a location that regularly consumes more paste.
Those are planning considerations, not measured waste or contamination advantages. The jar and tube instructions direct users to dispense the amount needed onto a working surface and keep containers tightly closed when not in use. Follow the applicable handling procedure rather than making container size a substitute for it.
Tubes: compare the delivery method, not just the net weight
The three-tube and three-small-jar formats both total 342 g, so their quoted package prices can be compared directly on mass. The separate question is whether your team needs a tube or a jar for its approved preparation routine. A tube is not automatically single-use, and its presence does not establish less waste or a sterile product.
Single-use cups: compare cost per opening as well as per gram
Weaver's single-use cup instructions require the opened paste to be used on only one patient and then discarded. Do not divide the price across several patients by planning to retain the remaining contents.
For a 24-cup quote, divide the total by 24 to find the cost of opening one cup. Divide by 360 g to compare purchased paste mass. These calculations answer different questions.
A 15 g cup is a package quantity, not a prescribed application amount or a guarantee of one complete study. If an approved workflow consumes two cups for a patient, the paste-container cost is twice the per-cup cost. When one cup provides more than needed, its unused remainder still belongs in that patient's supply cost.
Single-use packaging can be a workflow requirement. It is not, by itself, evidence that cups are cheaper, sterile, or clinically superior to another Ten20 format.
Cost per gram is not the same as cost per completed study.
Net weight cannot tell you how many EEG, PSG, or other compatible recordings a jar will support. The electrode setup, amount dispensed, additional applications, and material discarded all affect consumption.
For an internal comparison, track paste dispensed and paste discarded over a consistent group of comparable studies. Assign cost to that consumed material rather than charging the entire newly purchased order to the first week's patients. Keep unopened or otherwise usable stock remaining at the end of the review separate.
Paste cost per completed study = cost of paste consumed, including discarded paste ÷ number of comparable studies completed.
Keep staff time, electrodes, preparation gel, and other supplies outside this paste-only calculation, or itemize them separately. The goal is to understand purchasing consumption, not to reduce the amount of paste required by the product instructions or clinical procedure.
We do not assign a universal patient yield to either jar. For planning the rest of the cart, use our EEG and sleep lab electrode supply checklist.
Check the remaining shelf life before accepting a larger order.
Weaver describes a three-year labeled shelf life and prints the lot and expiration information on each container. That is not a promise of three years remaining on the day your order arrives, and opening a jar does not restart its expiration clock.
Ask about the available lot when remaining shelf life matters to the order. Compare expected use with the marked date and applicable handling requirements. Do not apply general jar-storage guidance to a single-use cup after opening.
Our NuPrep and Ten20 storage, cleanup, and shelf-life guide covers the detailed handling questions. Keep that guidance with the stock-management process rather than treating a discount as permission to keep unsuitable paste.
What to confirm before ordering Ten20 in quantity
| Quote detail | What to record |
|---|---|
| Manufacturer reference | Exact item number and whether the container is a jar, tube, or single-use cup. |
| Priced quantity | Containers per pack, grams per container, and number of packs. Do not rely on the word "case" alone. |
| Comparable total | The selected format's price after applicable discounts, plus delivery and fees, with consistent tax treatment. |
| Stock requirements | Original containers needed at each location, remaining shelf life, and acceptable lot information. |
| Delivery requirement | Required quantity, destination, and arrival date; confirm availability for the actual order. |
A precise request might read: "Please quote four packs of Weaver 10-20-4: twelve 4 oz / 114 g jars in total. Confirm price, shipping, available quantity, and remaining shelf life. We will provide the delivery ZIP code and required date."
Send our team the item number and pack quantity when you need clarification. A low per-container price is not useful if the quoted quantity or format is different from the one your department approved.
Ten 20-size and cost questions
Does a 4 oz three-pack contain 4 oz altogether?
No. Each jar contains 4 labeled ounces. Three jars total 12 oz / 342 g. Likewise, three 8 oz jars total 24 oz / 684 g.
How do I check a listing described as TEN20-8J conductive paste, 3/pack?
Weaver identifies its 8 oz jar three-pack as 10-20-8. Some marketplaces use the part number TEN20-8J. They are the same product. Match that reference, three jars, and 228 g per jar to the quote before treating a seller's different code as the same package.
Can I compare Ten20 by fluid ounces or milliliters?
Use the labeled net mass for these comparisons. Do not substitute fluid ounces, milliliters, or gross shipping weight for the stated grams of paste. When a listing uses a different unit without enough detail, request clarification before comparing its unit price.
Is an 8 oz jar a stronger version of Ten20?
The size describes the amount supplied, not a stronger grade. The manufacturer's common jar and tube instructions cover both jar references. Choose the package for the approved workflow and consumption rather than assuming a performance difference from its size.
Can we buy NuPrep instead if its price per gram is lower?
No. They perform different jobs. Our Ten20 vs. NuPrep guide explains the paste used with the recording electrode versus the preparation gel used before placement. A lower unit price does not make the products substitutes.
Choose the package around the work, then compare the price.
Start with the approved format and number of original containers you need. Compare equal amounts of paste, check remaining shelf life, and use actual consumption when evaluating longer-term cost.
Review our current Ten20 4 oz and 8 oz three-jar options to select the package and confirm today's price.
Ten20's manufacturer instructions limit use to compatible non-gelled neurodiagnostic electrodes and intact skin. Avoid eye contact, respond to irritation, and do not use it with current-inducing electrodes such as TENS or NMES stimulation electrodes. This purchasing comparison does not replace those instructions.
