Since 1982, M&W JAWO Sampling has been a pioneer in automated sampling, with over 1,000 projects implemented across 85 countries — making us one of the world’s oldest, most experienced, and trusted specialists in the field.
We offer a complete range of automated solutions that cover the entire sampling lifecycle. Beyond collecting accurate and representative samples of bulk materials, granules, and fines, our expertise extends to integrated sample preparation, automated material transportation, and advanced online analysis units. This ensures a seamless process where your data remains the reliable foundation for every business decision.
What sets us apart is our commitment to customization. We understand that no two plants are identical; therefore, we don’t offer “one-size-fits-all” products. Instead, every system—from the primary sampler to the final analysis unit—is engineered-to-order to fit your specific plant layout and unique operational requirements.
As a true one-stop shop, we handle everything in-house: from mechanical and electrical engineering to manufacturing and our own PLC control systems. By owning the entire production process, we guarantee faster delivery times and the lifelong availability of spare parts. Whether you are in mining, metals & minerals processing, fertilizers, energy, or cement, we provide the security that only a manufacturer with 40 years of global expertise can deliver.

Our complete in-house capabilities include:
With all core competencies in-house, M&W JAWO Sampling delivers complete turnkey sampling and sample preparation solutions…
Technically driven project management with one dedicated point of contact. Mechanical, electrical and control system expertise combined with structured execution. FAT coordination and systematic verification that delivered systems comply with contractual and technical requirements.
Documentation, manuals and acceptance records are included. Installation supervision and SAT support are provided, while commissioning involvement is defined case by case. This ensures controlled interfaces and predictable execution across the entire sampling lifecycle.
Mechanical, electrical and process engineering focused on automated representative sampling, plant integration and long-term operational reliability.
Where relevant, we test and evaluate sampling solutions using customer materials (e.g. copper concentrates, minerals, fuels) to understand the impact of particle size, moisture, segregation and flow behavior — ensuring the right design choices from the outset.
In-house manufacturing including CNC machining as well as welding and metalwork, ensuring full control of tolerances, materials and build quality — from individual components to complete sampling systems.
Integrated automation and control systems enabling reliable operation, data integrity and seamless integration with plant control systems.
System assembly, functional testing and complete technical documentation to support commissioning, handover and contractual or regulatory requirements.
Structured quality assurance throughout engineering, manufacturing and testing — ensuring consistent performance and traceability.
Ongoing service support and in-house manufactured spare parts, ensuring short lead times and availability throughout the system lifecycle.
You will be assured sampling solutions which produce consistent samples for your quality analysis – accurately and precisely representing the total lot.
Obtaining representative samples of the total lot before analysis is crucial – otherwise, there is little point in having made significant investments in laboratory equipment and analytical competencies.
From the beginning, in1982, M&W JAWO Sampling has been pioneer and led the way in the development, engineering and production of automated sampling equipment and solutions – with over 1,000 projects completed in more than 85 countries around the world
