Description
The Mixpac MFQ 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. MFQ mixers are the 1:1 and 2:1 ratio version of the QUADRO line and carry green elements with a white interface. The 4:1 and 10:1 version is the MFQX, which uses an orange 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 MFH series. Both run the same 1:1 and 2:1 F-System cartridges, so the choice comes down to nozzle length, tip style, and bore.
- Shorter overall. MFQ nozzles run 100 mm to 198 mm. The MFH helix line runs 156 mm to 362 mm. Where fixture clearance is tight, QUADRO is the shorter option.
- Three tip styles. Stepped, straight, and luer. The MFH 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. MFQ starts at 5.3 mm against MFH’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 MFQ 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 MFQ model code
Using MFQ 08-24T as the example:
| Code segment | Meaning |
|---|---|
| MFQ | Mixer, F-System, QUADRO design. No X means 1:1 and 2:1 (white interface). An X means 4:1 and 10:1 (orange 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, D is straight. |

Choosing an MFQ 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 the ratio before anything else. MFQ is 1:1 and 2:1 only. If your cartridge is 4:1 or 10:1, you need the MFQX with the orange interface.
Compatible F-System cartridge assemblies
| Cartridge system | Ratio | Fill volume | Mixpac article |
|---|---|---|---|
| F-System 200 Industrial | 1:1 | 210 ml | AF 200-01-10-01 (PP), AF 200-01-30-01 (PA) |
| F-System 200 Industrial | 2:1 | 215 ml | AF 200-02-10-01 (PP), AF 200-02-30-01 (PA) |
| F-System 400 Industrial | 1:1 | 395 ml | AF 400-01-10-01 (PP), AF 400-01-30-01 (PA) |
| F-System 400 Industrial | 2:1 | 400 ml | AF 400-02-10-01 (PP), AF 400-02-30-01 (PA) |
The 200 and 400 designations refer to the cartridge body size, not the fill volume. Running a 4:1 or 10:1 cartridge instead? Use the MFQX series with the orange interface. The ratios do not interchange.
MFQ 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 (this page) | 1:1 and 2:1 | QUADRO, green elements with white interface | 100 to 198 mm | Stepped, straight, or luer |
| MFQX | 4:1 and 10:1 | QUADRO, green elements with orange interface | 101 to 198 mm | Stepped, straight, or luer |
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 MFQ and MFQX mixers?
MFQ mixers have a white interface and are built for 1:1 and 2:1 cartridges. MFQX mixers have an orange interface and are built for 4:1 and 10:1. Both use green QUADRO elements and the same lengths and bores, but the ratios do not interchange. Check the interface color on the nozzle against the ratio on your cartridge.
What is the difference between MFQ and MFH mixers?
Both fit the same 1:1 and 2:1 F-System cartridges. MFQ uses square QUADRO elements in a square housing and runs 100 to 198 mm with three tip styles. MFH uses round helix elements and runs 156 to 362 mm with a stepped tip only. The QUADRO line is the shorter option and the only one with a luer tip.
What do the numbers in MFQ 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. No X in the name means it is the 1:1 and 2:1 version.
Which MFQ 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.
Which MFQ diameter should I use?
Match the bore to your bead and flow requirement. A 5.3 mm bore gives the finest bead and lowest output. A 10.7 mm bore gives the highest flow and lowest pressure drop, which helps on higher viscosity materials and larger beads.
Does an MFQ mixer need a converter or retaining nut?
No. The MFQ mounts directly to the F-System cartridge with a twist and lock connection. No converter, no retaining nut, no tools.
