Description
The Mixpac MFQX static mixer by medmix (formerly Sulzer Mixpac) is a disposable QUADRO mixing nozzle for dispensing two-part adhesives from F-System cartridges, also called F-Series cartridges. MFQX mixers are the 4:1 and 10:1 ratio version of the QUADRO line and carry green elements with an orange interface. The 1:1 and 2:1 version is the MFQ, which uses a white interface. Six sizes are available across four bore diameters and three outlet tip styles.
QUADRO or helix: which F-System mixer to run
QUADRO mixers use square-profile elements in a square housing rather than the round helix elements in the MFHX series. Both run the same 4:1 and 10:1 F-System cartridges, so the choice comes down to nozzle length, tip style, and bore.
- Shorter overall. MFQX nozzles run 101 mm to 198 mm. The MFHX helix line runs 156 mm to 363 mm. Where fixture clearance is tight, QUADRO is the shorter option.
- Three tip styles. Stepped, straight, and luer slip. The MFHX line is stepped tip only. A luer tip matters when the nozzle feeds a valve or fitting rather than dispensing straight to the part.
- Smaller bores available. MFQX starts at 5.3 mm against MFHX’s 6.0 mm, and the 05 series are the shortest F-System mixers in either line.
- Element count is mostly fixed. Four of the six MFQX sizes carry 24 elements. Only the 05-16L (16) and the 08-32D (32) differ, so bore and tip are the real selection variables here, not element count.
Reading the MFQX model code
Using MFQX 08-24T as the example:
| Code segment | Meaning |
|---|---|
| MFQ | Mixer, F-System, QUADRO design |
| X | Version for 4:1 and 10:1 cartridges (orange interface). No X means 1:1 and 2:1 (white interface). |
| 08 | Inner diameter, rounded. The 05 is 5.3 mm, the 07 is 7.5 mm, the 08 is 8.7 mm, the 10 is 10.7 mm. |
| 24 | Number of mixing elements |
| T, L, or D | Outlet tip. T is stepped, L is luer slip, D is straight. |

All MFQX models use green QUADRO elements with an orange interface. The 08-24T-S13 is the greenLine version of the 08-24T, built from recycled content rather than virgin plastics, with identical dimensions and performance. It is not a stocked item. Call for availability and lead time.
Choosing an MFQX nozzle
- Start with the tip. If the nozzle feeds a valve, manifold, or fitting, the 05 series luer tips are the ones that mate. If it dispenses to the part, the stepped tips cover 7.5 through 10.7 mm bore. The 08-32D straight tip suits applications needing an unstepped outlet.
- Then the bore. Larger inner diameter means higher flow and lower pressure drop. Smaller bore gives a finer bead and tighter placement.
- Element count only matters at the ends of the range. The 05-16L runs 16 elements for lower resistance in the smallest bore. The 08-32D runs 32 for materials needing more mixing passes. The other four are all 24.
- Check retained volume. Every nozzle holds material that stays inside at changeover, from 3.07 ml on the 05-16L to 14.92 ml on the 10-24T. Worth calculating if you change nozzles often or dispense small shots.

|---|---|---|---|
| F-System 200 Industrial | 4:1 | 225 ml | AF 200-04-10-01 (PP), AF 200-04-20-01 (PBT) |
| F-System 200 Industrial | 10:1 | 250 ml | AF 200-10-10-01 (PP), AF 200-10-20-01 (PBT) |
| F-System 400 Industrial | 4:1 | 415 ml | AF 400-04-10-01 (PP), AF 400-04-20-01 (PBT) |
| F-System 400 Industrial | 10:1 | 490 ml | AF 400-10-10-01 (PP), AF 400-10-20-01 (PBT) |
The 200 and 400 designations refer to the cartridge body size, not the fill volume. Running a 1:1 or 2:1 cartridge instead? Use the MFQ series with the white interface. The ratios do not interchange.
MFQX compared to the other F-System mixers
The F-System line uses interface color to signal mix ratio. White or natural means 1:1 and 2:1. Orange means 4:1 and 10:1.
| Series | Mix ratios | Element design | Length range | Tip options |
|---|---|---|---|---|
| MFH | 1:1 and 2:1 | Helix, white elements | 156 to 362 mm | Stepped |
| MFHX | 4:1 and 10:1 | Helix, orange elements | 156 to 363 mm | Stepped |
| MFQ | 1:1 and 2:1 | QUADRO, green elements with white interface | 100 to 181 mm | Stepped or luer slip |
| MFQX (this page) | 4:1 and 10:1 | QUADRO, green elements with orange interface | 101 to 198 mm | Stepped, straight, or luer slip |
Performance in production
- Square QUADRO element geometry divides and recombines the A and B sides through a square flow path rather than a helical one.
- Twist and lock F-System connection mounts directly to the cartridge with no converter and no tools.
- Disposable construction avoids purging and cleanup between adhesive batches.
- Shorter nozzle bodies across the whole line help where fixture clearance or operator reach is limited.
- Luer tips on the 05 series mate with valves and fittings, which the stepped-tip-only helix lines cannot do.
- Higher element counts add nozzle length and flow resistance. Check clearance and gun thrust before moving from 16 or 24 to 32 elements.
Common applications
- Electronics and communications assembly where a small bead and short nozzle are needed
- Metered dispensing through valves or fittings using the luer tip sizes
- Aerospace and aircraft sub-assembly with two-part structural adhesives
- Automotive body, glass, and trim attachment with methacrylate or polyurethane
- Transportation, marine, and composite assembly with structural adhesives
- Dispensing epoxy, polyurethane, silicone, acrylic, and MMA two-part adhesives and sealants

Frequently asked questions
What is the difference between MFQX and MFHX mixers?
MFQX uses square QUADRO elements in a square housing. MFHX uses round helix elements in a round housing. Both fit the same 4:1 and 10:1 F-System cartridges. MFQX nozzles are shorter across the board and offer three tip styles. MFHX offers more bore and element combinations and goes up to 363 mm.
What do the numbers in MFQX 08-24T mean?
The 08 is the inner diameter rounded down, actually 8.7 mm. The 24 is the number of mixing elements. The T means a stepped outlet tip. The X means it is the 4:1 and 10:1 version.
Which MFQX tip style do I need?
A stepped tip dispenses straight to the part and covers the 07, 08, and 10 bore sizes. A luer tip on the 05 series mates with valves, manifolds, and fittings. The straight tip on the 08-32D gives an unstepped outlet where a consistent bore to the opening matters.
What is the MFQX 08-24T-S13?
It is the greenLine version of the MFQX 08-24T, built from recycled content instead of virgin plastics. Dimensions, element count, retained volume, and box quantity are identical to the standard 08-24T. It is not a stocked item at Chemical Concepts. Call (800) 220-1966 for availability and lead time.
How much adhesive stays in an MFQX nozzle?
Retained volume runs from 3.07 ml on the MFQX 05-16L to 14.92 ml on the MFQX 10-24T. See the size chart above for the value on each model. Worth checking if you change nozzles often or dispense small shots.
Will an MFQX mixer work on a 1:1 cartridge?
No. MFQX nozzles are built for 4:1 and 10:1 ratios and carry an orange interface. For 1:1 and 2:1 F-System cartridges, use the MFQ series with the white interface.
Does an MFQX mixer need a converter or retaining nut?
No. The MFQX mounts directly to the F-System cartridge with a twist and lock connection. No converter, no retaining nut, no tools.
