A primary sampler can collect the right increment, and that sample can be processed correctly — yet the result can still be compromised before it reaches the laboratory. Moisture loss, dust ingress, carry-over, overflow and sample mix-ups can turn good sampling into unreliable data.
The M&W JAWO Sample Magazine (SM) is the final collection and storage stage of an automated sampling system. It receives the sampled material, fills a dedicated bucket, keeps it inside a closed housing and indexes the next bucket automatically. Operators do not need to stand at the filling point.
That matters commercially. A lost fine fraction can change particle-size distribution. Uncontrolled moisture exchange can affect a contractual result. An incorrectly labelled bucket can attach a correct sample to the wrong batch. The SM is designed to protect the sample after collection, when it may wait hours or even days before it is taken to the laboratory.
Installed at the end of the sampling line, the SM receives material through a top-mounted inlet. Before filling, the selected bucket is raised towards the inlet. This closes the transfer gap so the increment enters the bucket rather than landing in the housing. After the assigned increments have been collected, the bucket is lowered, the carousel indexes and the next empty bucket is raised. In the tight version, each bucket is lifted and pressed against a gasket to maintain sealing during both filling and storage.
Filled buckets remain inside the closed housing until an operator removes them through the access door. The safety switch deactivates the carousel before access is possible.
M&W JAWO offers three collection concepts. The right choice depends on sample-integrity requirements, access during operation, storage capacity and whether interleaved samples are needed.
In short: choose SM for maximum enclosure and sample integrity; SML for continuous access; DS for compact dual-container collection and interleaved sampling.
Every Sample Magazine is engineered according to the specific characteristics of the application, including:
Process and material data
Installation data
Send us the required sample mass per lot, lots between operator visits, material properties, collection interval and available space. We will recommend the SM configuration, bucket type, sealing and identification method for your duty.

The SM is positioned downstream of the primary sampler and any sample processing and handling equipment. Filled buckets containing the final samples are then delivered to sample preparation or the laboratory.
M&W JAWO Sampling can engineer the complete process — from primary sampling through secondary sampling, division, crushing and material transfer to sample collection and storage, including system automation and control. This ensures seamless integration of all interfaces, allowing the complete process to operate as a single, cohesive solution.
The Sample Magazine consists of a carousel carrying the sample buckets inside a closed housing, a top-mounted inlet, a bucket lifting mechanism and a drive motor, with a junction box and control interface.
In batch tracking mode, the carousel moves to the position assigned to the active batch, allowing several batches or material streams to be collected in parallel within one unit.
The Sample Magazine is used wherever an automated sampling system produces samples that must be stored, identified and transported without losing the properties that were sampled. Final suitability depends on the material, required sample mass, collection interval and installation conditions.
Dry and moist free-flowing bulk materials including coal, coke, ores, concentrates, cement, clinker, limestone, fertilizers, biomass, chemicals, aggregates and recovered fractions. Very sticky or bridging materials require an individual assessment because build-up at the inlet or bucket rim can affect transfer and stored mass.
*Indicative values from previous projects
Functionally, yes. These terms describe equipment that fills, stores and often identifies sample containers at the end of an automated sampling system.
Standard configurations range from six to ten buckets and 3.6 to 120 litres. The SM is custom-designed, so other quantities and volumes can be considered for the duty.
Yes. Batch tracking can assign defined buckets to defined batches, vendors, grades or process streams. The carousel then indexes to the assigned position.
Samples can be identified manually or with optional RFID configured to the required read point and data workflow. RFID can link the physical bucket to the relevant sample, batch, shift or laboratory record.
The SM access door is safety-interlocked and the carousel is deactivated before access. Sampling is therefore paused during bucket removal; if continuous access is required, consider the Linear Sample Magazine (SM-Li).
It is intended for dry and moist free-flowing bulk materials including coal, coke, ores, concentrates, cement, clinker, limestone, fertilizers, biomass, chemicals, aggregates and recovered fractions. Very sticky or bridging materials require individual assessment.
Usually it can, provided the sample route can be directed to the inlet and sufficient floor area and access clearance are available. Final suitability is confirmed from the layout and sampling regime.
The applicable international sampling standards are agreed in the project specification. The equipment is engineered according to TOS principles, international sampling standards and other guidelines relevant to the delivery.
