Laboratory z-arm kneader for high-viscosity materials
Ideal for R&D, this advanced Z-arm kneader efficiently handles high-viscosity materials, achieving thorough kneading and mixing for versatile applications from food to polymers, ensuring consistent quality in small-scale production.

Kneads, Mixes, and Extrudes High-Viscosity Materials
The GUITTARD LAB from HASLER Group is a robust Z-arm laboratory kneader and extruder designed for intricate laboratory and small-scale production processes. It stands out for its ability to knead, mix, and extrude high-viscosity materials across diverse applications such as fertilizers, ceramics, and battery components.
Employing a dynamic Z-arm mechanism, it ensures thorough mixing by rotating two blades on parallel shafts in contra directions, efficiently dispersing and breaking down material agglomerates. This kneader accommodates up to 30 liters, making it ideal for low-volume, high-precision batches in industries ranging from chemicals to food processing.
The equipment integrates seamlessly into laboratory settings with its straightforward installation—requiring only a power connection—and simple maintenance thanks to quick dismantling features. For operations demanding particular environmental safety and material properties, options like explosion-proof construction, vacuum systems, and heating elements are available, alongside stainless steel fabrication to resist corrosion.
GUITTARD LAB’s automated systems offer advanced operational flexibility, supported by a PC-based data acquisition tool that enhances monitoring and control capabilities. It complies with international standards such as CODAP, ASME, and TÜV, ensuring reliability and safety in your production line. For enhanced process efficiency, configuration support and customization options are offered to address specific operational needs, backed by HASLER Group’s comprehensive engineering support services.
