Bayonet Mixer Nozzle

For 50 mL Dual Cartridges (1:1 and 2:1 Ratios)

Btektech’s bayonet mixer nozzle delivers consistent, on-ratio blending for two-component adhesives in 50ml cartridges. Its secure twist-lock interface and multiple tip styles support precise, controlled dispensing in demanding production environments.

Product Advantages & Technical Features

Designed for flawless small-volume dispensing, this high-performance bayonet mixer nozzle guarantees homogeneous mixing of two-part epoxies, polyurethanes, and silicones — whether applied manually or with pneumatic guns. The robust bayonet twist-lock system allows tool-free, ultra-fast nozzle changes, keeping production lines moving without interruption.

Perfectly supports 1:1 and 2:1 ratios with outstanding mixing consistency
Secure bayonet interface engineered for hundreds of repeated attachments
Wide selection of tip styles: stepped, tapered, straight, Luer lock, Luer slip, and H-tapered
Traditional round helical mixing elements for thorough blending
Shorter square-profile mixing elements that dramatically reduce retained volume and material waste while preserving excellent homogeneity

Product Applications & Industries

Engineered for applications that demand absolute ratio accuracy and repeatability from 50 ml dual cartridges. Its advanced traditional helical or square mixing elements and low-shear flow path produce uniform curing results across challenging chemistries.

Frequently Asked Questions (FAQ)

Q1 What cartridge systems does this bayonet mixer nozzle fit?

It locks securely onto all industry-standard 50 ml dual cartridges and reliably handles 1:1 and 2:1 mix ratios with zero leakage.

Q2 Can I attach dispensing needles for micro-precision output?

Yes, models with luer-lock outlets accept precision needles directly, enabling consistent beads well below 1 mm for electronics and medical assembly.

Q3 How many mixing elements provide the best performance?

More elements ensure superior homogeneity, especially with high-viscosity or fast-reacting materials, delivering uniform cure and maximum bond strength in critical assemblies.

Q4 Are these nozzles reusable?

They are engineered as single-use to eliminate cleaning, prevent cross-contamination, and guarantee consistent, contamination-free results every time.

Q5 What materials are used in the nozzle construction?

The housing uses tough, chemical-resistant polypropylene (PP), while the mixing elements are precision-molded from low-friction POM (Acetal) for smooth flow, minimal pressure drop, and long-term reliability.
