A representative sample only remains useful if it is handled correctly after collection. The Stainless Steel Sample Bucket (SSB) from M&W JAWO Sampling is a robust sample container for receiving, storing and moving sampled material in industrial sampling and sample preparation workflows.
The SSB is available as a standard version with lid and can be customised for specific handling requirements with options such as wheels, airtight lid, outlet chute and Radio Frequency Identification (RFID). Typical volumes are 6 L, 10 L and 15 L, and the bucket can also be customised to match the handling route, material characteristics and sampling system layout.
The SSB receives and holds sampled material after it has been collected by the sampling system. It supports the physical step between sample collection, internal transport, sample preparation and laboratory analysis.
A sample bucket is an important part of the sampling chain. Automated sampling systems are designed to collect representative increments from the material stream, but the sample can still lose value after collection if it is exposed to contamination, moisture change, wrong identification, sample loss or inconsistent handling. The SSB supports controlled sample handling where cleanability, durability and traceability matter.
| Feature | What it means | Benefit |
|---|---|---|
| Crack- and crevice-free design | Reduces areas where residual material can remain after emptying or cleaning. | Helps reduce contamination risk between samples and supports more reliable sample handling. |
| Stainless/acid-proof steel | Available in EN 1.4301 and EN 1.4401. | Supports demanding industrial environments where durability and material compatibility matter. |
| TIG-welded construction | Provides a controlled welded design for industrial use. | Supports long service life and predictable handling in daily operation. |
| Customised configuration | Can be supplied with wheels, airtight lid, outlet chute or other adaptations. | Allows the bucket to fit the sampling system instead of forcing operators to adapt the process. |
| RFID option | Electronic identification can be added to tag the bucket. | Supports traceability, correct handling and reduced risk of sample mix-ups. |
The SSB uses stainless/acid-proof steel, controlled TIG welding and a crack- and crevice-free construction to support robust and cleanable sample handling. Surface finish can be adapted depending on the application, including 2B cold-rolled finish, sanding to the required grit size, electro-polishing or glass-bead blasting.
Where required, the bucket can be configured for the actual sampling system instead of being treated as a generic container. RFID identification can be added to connect the physical bucket to the correct sample, batch, line, shift or laboratory workflow. In sampling operations where several buckets are handled at the same time, this can reduce the risk of manual errors and improve traceability.
The SSB is relevant for industrial sampling systems where the collected sample must be handled in a controlled, durable and cleanable container. It is especially relevant in Mining, Metals & Minerals Processing, Cement, Fertilizers, Chemicals and Energy & Power Generation. It may also be relevant in Precious & Base Metals Recycling, Laboratory & Research and selected Food & Feed applications, depending on material compatibility, cleaning requirements and the required bucket configuration.
| Industry | Typical relevance for Stainless Steel Bucket |
|---|---|
| Mining | Robust handling of abrasive ores, concentrates, coal and similar bulk materials. |
| Metals & Minerals Processing | Controlled sample handling between production, preparation and laboratory analysis. |
| Cement | Durable handling of clinker, cement, raw meal, lime and other dusty or abrasive materials. |
| Fertilizers | Controlled handling of granules, powders and chemically active materials. |
| Chemicals | Cleanable handling where material compatibility and controlled workflows are important. |
| Energy & Power Generation | Sample handling for coal, coke, petcoke, ash and biomass-related applications. |
| Precious & Base Metals Recycling | Relevant where material value, contamination risk and traceability requirements are high. |
| Laboratory & Research | Relevant where durable, cleanable containers are required in controlled sample workflows. |
| Food & Feed | Relevant only where stainless steel handling, cleaning requirements and material-contact conditions are suitable. |
The SSB can be used in sampling workflows for a wide range of dry bulk materials where a robust and cleanable sample container is required. Final suitability depends on the material, sample volume, cleaning requirements, temperature, moisture, abrasiveness and the required handling route.
| Material group | Typical sample materials |
|---|---|
| Coal, Coke & Petcoke | Coal, coke, petcoke and fly-ash where robust sample handling is required. |
| Iron, Chrome & Manganese | Iron ore, iron concentrate, iron pellets, chrome ore and manganese ore. |

| Gold & Precious Metals | Gold ore, gold concentrate, gold tailings and mixed precious metals concentrate. |
| Bauxite, Lithium, Magnesit, Titanium & Specialty Ores | Bauxite, spodumene/lithium materials, magnesit and other specialty ores, subject to application review. |
| Cement & Lime | Clinker, cement, raw meal, limestone, lime and cement by-pass dust. |
| Fertilizers | Potash, phosphate, urea, NPK and ammonium nitrate. |
| Chemicals & Plastics | Carbon black, catalyst, plastic granulates, powder, polysilicon and talc. |
| Recycled Materials | Battery/black mass, catalyst, industrial by-products, metal scrap and selected mixed recycled streams, subject to compatibility and safety review. |
| Food & Agriculture | Animal feed pellets, grains, seeds and sugar only where stainless steel handling, cleaning and any material-contact requirements are suitable. |

The SSB is often used as part of a larger M&W JAWO Sampling system. In systems where sampled material must be split or directed into different sample routes, the bucket may be used together with the Diverter Gate (DG) or the Dual Splitter (DS).
For complete sampling-system context, the SSB can also be positioned within the Bucket Sampling Solution, where sampled material may pass through equipment such as a bucket sampler, screw conveyor, rotary tube divider, diverter gate, dual splitter and sample container route.
The right sample bucket should fit the sampling process, not just the shelf. Contact M&W JAWO Sampling if you need a stainless steel sample bucket configured for your material, sampling system and handling requirements.
