Description
The Mixpac MBH static mixer by medmix (formerly Sulzer Mixpac) is a disposable helix mixing nozzle for dispensing two-part adhesives from B-System AB cartridges. MBH mixers are the 1:1 and 2:1 ratio version of the B-System helix line and carry a dust grey body with white elements. The 4:1 and 10:1 version is the MBHX, which has orange elements. Seventeen models are available, differing in bore, element count, and tip style.
B-System or F-System: check your cartridge first
B-System and F-System nozzles are not interchangeable. B-System covers the smaller 25 ml and 50 ml AB cartridges used for repair work, small assemblies, and sample quantities. F-System covers the larger 200 and 400 series cartridges used in production. If your cartridge holds 200 ml or more, you need an MFH or MFQ instead.
Reading the MBH model code
Using MBH 05-16T as the example:
| Code segment | Meaning |
|---|---|
| MBH | Mixer, B-System, helix design |
| No X | Version for 1:1 and 2:1 cartridges, with white elements. An X, as in MBHX, means 4:1 and 10:1 with orange elements. |
| 05 | Inner diameter, rounded down to a whole millimeter. Actually 5.4 mm on this model. The five bores run 3.2, 4.2, 5.4, 6.5, and 7.5 mm, coded 03, 04, 05, 06, and 07. |
| 16 | Number of mixing elements. MBH models have 6, 11, 12, 14, 16, or 20. |
| T | Outlet tip. T is stepped, D is straight, S is tapered, and L is luer slip. T does not stand for tapered. |

Choosing between the seventeen
All seventeen models fit the same B-System 1:1 and 2:1 cartridges. Four things change from model to model.
- Bore. The first two digits of the model code. A smaller bore holds less material, from 0.49 ml in the 3.2 mm 03-12D to 3.76 ml in the 6.5 mm 06-20T. A larger bore passes more material and generally gives more mixing margin, at the cost of more adhesive left in the nozzle. The 07-11D is the only 7.5 mm model.
- Elements. The 5.4 mm bore comes in five element counts: 6, 12, 14, 16, and 20 (05-06T, 05-12D, 05-14D, 05-16T, 05-20T). More elements means more mixing passes and a longer nozzle. Watch the bead before settling on a lower element count.
- Tip. Straight, tapered, stepped, or luer slip. Compare 03-16D with 03-16S, or 04-16D with 04-16S. The tapered version is 5.5 mm to 9.8 mm longer than the straight tip at the same bore and element count. The 03-16L is the only luer slip model.
- Retained volume. On a 25 ml or 50 ml cartridge, 0.49 ml to 3.76 ml stays in the nozzle at every changeover. Worth factoring in if you swap nozzles often or dispense in small shots.

Running a 4:1 or 10:1 B-System cartridge instead? Use the MBHX series with orange elements. The ratios do not interchange.
You also need a gun that matches the cartridge size, ratio, and flange. Call us with your cartridge and we will match the gun.
MBH compared to the other B-System mixers
The B-System line uses element color to tell the ratio version apart. White or green elements mean 1:1 and 2:1. Orange elements mean 4:1 and 10:1.
| Series | Mix ratios | Element design | Models |
|---|---|---|---|
| MBH (this page) | 1:1 and 2:1 | Helix, white elements in a dust grey body | Seventeen models, 03-12D to 07-11D |
| MBHX | 4:1 and 10:1 | Helix, orange elements in a dust grey body | Nine models, 03-16S to 06-20T |
| MBQ | 1:1 and 2:1 | QUADRO, green elements in a dust grey body | 05-16L, 05-24L |
| MBQX | 4:1 and 10:1 | QUADRO, orange elements in a dust grey body | 05-16L, 05-24L |
Performance in production
- Helical elements blend the A and B sides as the material travels the length of the nozzle.
- B-System twist and lock connection mounts directly to the AB cartridge with no converter and no tools.
- White elements in a dust grey body make the 1:1 and 2:1 version easy to tell apart from the orange element MBHX at the bench.
- Five bores from 3.2 mm to 7.5 mm let you size the bead and the mixer to the joint without changing cartridge system.
- Straight, tapered, stepped, and luer slip tips are available, with element counts from 6 to 20.
- Disposable construction avoids purging and cleanup between adhesive batches, and the smaller models hold as little as 0.49 ml at changeover.
Common applications
- Small-batch and repair bonding from 25 ml and 50 ml cartridges
- Two-part chemistries that ship in 1:1 and 2:1 cartridges
- Electronics and small component assembly where a fine bead is needed from the 3.2 mm and 4.2 mm models
- Sample and trial dispensing before committing to a production cartridge size
- Field service and maintenance work with portable cartridge guns
- Dispensing epoxy, polyurethane, silicone, acrylic, and MMA two-part adhesives and sealants

Ordering
The 06-20T can be ordered individually, which makes it the one to start with when you want to test a nozzle with your material. The other models are sold by the case, and the case size is shown on each model page. Pair them with matching B-System cartridges from the dispensers, mixers, and nozzles category. Call or email about case orders or availability on any model.
Frequently asked questions
What cartridges does an MBH static mixer fit?
Mixpac B-System AB cartridges in 1:1 and 2:1 ratios, covering the 25 ml 1:1, the 50 ml 1:1, and the 50 ml 2:1 sizes. B-System nozzles do not fit F-System 200 or 400 series cartridges, which use the MFH or MFQ instead.
What is the difference between MBH and MBHX mixers?
Element color and ratio. MBH has white elements and is built for 1:1 and 2:1 cartridges. MBHX has orange elements and is built for 4:1 and 10:1. Both use a dust grey body and mount to B-System cartridges, but the ratios do not interchange. Check the element color against the ratio printed on your cartridge.
Which MBH model should I start with?
The 06-20T is a good first test. It has 20 elements, the highest count in the series, and it is the longest nozzle at 157.0 mm. It can be ordered individually. If the joint needs a finer bead, step down a bore, to the 05-16T at 5.4 mm or the 03-16S at 3.2 mm. If the mixed bead shows streaking, color variation, or uneven cure, step up in element count at the same bore.
What does MBH 05-16T mean?
MBH is mixer, B-System, helix design. No X means the 1:1 and 2:1 version with white elements. The 05 is the inner diameter rounded down, actually 5.4 mm. The 16 is the number of mixing elements. The T is the stepped outlet tip. D means straight, S means tapered, and L means luer slip.
What is the difference between MBH and MBQ mixers?
Element design. MBH uses helical elements in a round bore and comes in seventeen models across five bore sizes. MBQ uses QUADRO elements in a square flow path, in a 5.3 mm bore with 16 or 24 elements. Both are built for 1:1 and 2:1 cartridges, both mount to B-System cartridges, and MBH has white elements where MBQ has green.
Can I buy a single MBH nozzle?
If you want to order one nozzle to check fit or test a material, ask for the 06-20T. Call or email about other models and case sizes.
How much adhesive stays in an MBH nozzle?
From 0.49 ml in the 03-12D and 03-12S to 3.76 ml in the 06-20T. On a 25 ml or 50 ml cartridge that is a meaningful share of the pack, so it is worth factoring in if you change nozzles between shots rather than running a cartridge through on one nozzle. The size chart above lists every model.
Does an MBH mixer need a converter or retaining nut?
No. The MBH mounts directly to the B-System cartridge with a twist and lock connection. No converter, no retaining nut, no tools.
