Description
Adhesive that cures inside the mixing nozzle is money in the trash. Every purge, every stop in the run, and every nozzle you pull off the cartridge takes retained adhesive with it. On expensive epoxies and thermally conductive pastes it adds up fast.
The Xemex X2-C8-8S Low-Waste Static Mixer holds 4.3 mL of retained volume and replaces 32-element mixers using eight Xemex elements. At 86.3 mm it’s the shortest 8-element mixer in the C-system line, which puts the tip closer to the work surface.
The 8.7 mm inner diameter supports higher throughput for mid to high volume dispensing. The stepped outlet tip trims back to set bead diameter, so one mixer covers a range of bead sizes without swapping parts.
The straight bell connection fits C-System cartridge and meter-mix dispensers, so it’s a direct swap without changing equipment. Compatible with epoxies, methacrylates (MMA), urethanes, and silicones. Designed and manufactured in the United States.

The Xemex element geometry completes mixing in fewer elements, which shortens the mixer and cuts the amount of adhesive trapped inside it.

Patented Xemex Mixing Technology
Xemex inserts are additively manufactured, which allows internal geometry that conventional molded elements can’t produce. Each element multiplies the striation count, so eight Xemex elements do the work of 32 traditional square or helical elements in a much shorter body.
Performance in Production
- Eight Xemex elements replace 32-element traditional mixers, the highest mixing margin in the C-system line.
- 4.3 mL retained volume in a mixer that does the work of a much longer nozzle.
- Shortest 8-element C-system mixer at 86.3 mm, which improves reach and control near the substrate.
- 8.7 mm inner diameter supports higher adhesive flow rates for mid to high volume work.
- Stepped tip trims back to set bead diameter without swapping mixers.
- Straight bell connection fits existing C-System cartridge and meter-mix hardware with no equipment change.
Installation and Handling
- Fits standard C-system straight bell cartridge and meter-mix connections.
- Trim the stepped tip back one step at a time until the bead size is right. You can go smaller to larger, not the other way.
- Purge a short bead before the first shot to confirm both sides are flowing.
- Suitable for manual, pneumatic, and meter-mix dispensing systems.
- Replace the mixer once adhesive begins curing inside the nozzle.
- Leave the spent mixer on the cartridge between runs to seal it, then fit a fresh one for the next job.
Common Applications
- Industrial manufacturing. Structural bonding and assembly at mid to high volume.
- Electronics. Potting and encapsulation where complete mixing prevents soft spots.
- Transportation and aerospace. Structural bonding on production and repair work.
- Gasketing and sealing with adjustable bead size
- High-ratio and harder-to-mix formulations where extra mixing margin matters
Waste Volume Comparison
Retained volume is the adhesive left inside the mixer when you stop dispensing. It’s gone on every purge, every stop, and every changeover. Here’s what the X2-C8-8S holds against the mixers it commonly replaces.
| Mixer Model | Waste Volume |
|---|---|
| Medmix MCH 10-32T | 19.00 mL |
| Medmix MCH 10-24T | 14.60 mL |
| Nordson 160-824 (7700904) | 11.00 mL |
| Nordson 160-632 (7700856) | 9.00 mL |
| Medmix MCQ 08-32T | 8.44 mL |
| Medmix MCQ 08-24T | 7.28 mL |
| Xemex X2-C8-8S | 4.3 mL |

C-System Options
Four C-system mixers share the same straight bell connection and 8.7 mm inner diameter. Pick element count first, then tip.
| Part | Elements | Replaces | Outlet | Length | Retained Volume |
|---|---|---|---|---|---|
| X2-C8-8S (this page) | 8 | 32 elements | Stepped | 86.3 mm | 4.3 mL |
| X2-C8-8L | 8 | 32 elements | Luer-Lock | 98.8 mm | 4.3 mL |
| X2-C8-7S | 7 | 18 to 24 elements | Stepped | 78 mm | 2.9 mL |
| X2-C8-7L | 7 | 18 to 24 elements | Luer-Lock | 90 mm | 3.0 mL |
Eight elements or seven is a tradeoff. The 8-element mixers do the work of a 32-element traditional nozzle and give you margin on harder-to-mix or high-ratio materials. The 7-element mixers replace 18 to 24 element nozzles and hold noticeably less adhesive, which adds up on high-cost material run at volume. Stepped or luer-lock comes down to whether you are laying a bead or running threaded needle tips.

Frequently Asked Questions
Why is the 8-element X2-C8-8S shorter than the 7-element X2-C8-7L?
The tip accounts for it. A luer-lock fitting adds about 12.5 mm of length over a stepped tip, which is more than the 8.8 mm an extra mixing element adds. So the 8-element stepped mixer comes in at 86.3 mm while the 7-element luer-lock version measures 90 mm. You get more mixing elements in a shorter overall package, though the 8-element holds more adhesive.
What is the difference between the X2-C8-8S and the X2-C8-8L?
The outlet. Both run eight Xemex elements on the same straight bell connection with an 8.7 mm inner diameter and both hold 4.3 mL. The 8S has a trimmable stepped tip for direct bead work at 86.3 mm overall. The 8L has a luer-lock outlet that threads on dispensing needles and precision tips at 98.8 mm overall.
Which mixers does the X2-C8-8S replace?
Eight Xemex elements deliver mixing performance equivalent to a 32-element traditional square or helical mixer. In practice it commonly replaces Medmix MCQ 05-24L, 08-24T, and 08-32T, Medmix MCH 05-18T, 05-24T, 05-32T, 06-24T, 08-18T, 08-24T, 08-32T, and 10-32T, and Nordson 160-624, 160-632, and 160-824.
Will the X2-C8-8S fit my cartridge?
It fits standard straight bell connections on C-System cartridge and meter-mix dispensers. If your hardware uses a bayonet, threaded, or F-style outlet instead, use the matching Xemex connection style from the comparison table above.
Customer Feedback
“The new Xemex mixer worked fantastic with Dow 3-4207. Greatly reduces wasted potting material and also mixed the 2 parts very well. This is exactly what we needed.”
Direct Customer Quote
“My customer had sporadic curing issues running EP965LVLX with a .187 x 48 helical mixer they were using. They dispensed test patterns with Xemex and got a complete cure. They told me these mixing sticks work great.”
Sales Representative, Eastern US
“My customer tested the Xemex mixer with an expensive thermally conductive paste. It was easy to see the cost savings from wasting less material in the mixer compared to the helical mixer they were previously using. They ordered 50 on the spot.”
