The Stainless Steel Sampling Bucket (SSSB) protects sample integrity after collection. It creates value where exposure, material loss, contamination or sample mix-ups can weaken the link between the sampled material and the analysis result.
In automated and repeatable sampling workflows, the SSSB provides a highly durable, cleanable and identifiable container for receiving, storing and transporting sampled material between the sampling point, sample preparation area and laboratory.
The SSSB is available in typical sizes of 5 L, 10 L and 15 L, with custom sizes available upon request. For applications with specific handling or process requirements, it can be customized with options such as wheels, an airtight lid, or an outlet chute.
The SSSB is designed for free-flowing bulk samples, including those that are hot, very wet, sticky, sharp-edged, dense or strongly abrasive. Its crack- and crevice-free stainless steel construction supports demanding industrial environments where durability and material compatibility matter.
A sampling bucket must do more than hold material. It must help protect the sample against exposure, loss, contamination and mix-ups after collection:
M&W JAWO Sampling offers both plastic (PSB) and stainless steel sampling buckets (SSSB) for different sample-handling requirements:
| Use the SSSB when… | Use the PSB when… |
|---|---|
| The sample is hot, very wet, sticky, sharp-edged, dense or strongly abrasive. | The sample is dry or moist, free-flowing and handled at -25 °C to +60 °C. |
| High mechanical strength, washdown tolerance, impact resistance or temperature durability are key requirements. | A robust, lightweight bucket, sealable storage and easy manual handling improve the daily workflow. |
| The sample has high contamination sensitivity, high value, aggressive chemistry or demanding cleaning requirements. |
Exposure, loss, contamination and mix-ups create the same commercial problem: The analysis can no longer be trusted as a reliable representation of the collected sample.
| 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. | Withstands temperatures up to 250 °C, heavy abrasion, wet and sticky materials, and aggressive chemistry. |
| 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. |
Contact M&W JAWO Sampling for guidance on choosing the right bucket for your sampling system, material and sample-handling process.
The right sampling bucket must fit the complete workflow: sample collection, storage, transport and analysis.

The SSSB is well suited for use with the Sample Magazine (SM) from M&W JAWO Sampling, where sampling buckets are filled automatically after the sampling process has been completed.
The Sample Magazine also functions as a storage unit, as multiple buckets can be installed inside the magazine. This allows the system to continue the sample collection routine without requiring each filled bucket to be replaced immediately. Instead, the Sample Magazine rotates to the next empty bucket, while the filled bucket remains stored for later removal. This reduces manual intervention, saves operator time and supports more consistent sample handling.
For applications requiring tighter sample control, the Sample Magazine can be supplied in a tight version where the buckets are lifted against a gasket to help keep them sealed.
The SSSB can also be used in systems where sampled material is split or directed into different sample routes, for example together with the M&W Dual Splitter (DS), where buckets are filled in parallel or according to defined sample routes.
The SSSB is relevant for industrial sampling systems where mechanical strength, chemical resistance, temperature tolerance and multi-bucket routines are important. It is especially useful where samples are collected into several buckets over time and where operators should not have to replace a bucket immediately after every filling cycle.
The table below shows typical application examples. It is not an exhaustive list of all industries or materials where the SSSB may be used.
| Industry | Typical Stainless Steel Sampling Bucket use |
|---|---|
| Mining | Iron ore, manganese ore, chromite, bauxite and other hard, coarse ores, wet or sticky drill cuttings and high-temperature samples where plastic containers would deform or wear prematurely. |
| Metals & Minerals Processing | Hot sinter, slag, calcine, abrasive concentrates and wet filter cake samples moving between production, sample preparation and laboratory analysis. |
| Cement | Hot clinker, kiln feed and abrasive cement mill samples at elevated temperatures or with high cleaning requirements between batches. |
| Fertilizers | Corrosive or hygroscopic materials such as ammonium nitrate, superphosphate and wet process intermediates where chemical resistance and thorough cleaning between samples are required. |
| Chemicals | Caustic soda, carbon black, soda ash, titanium dioxide, catalyst powders and similar aggressive or contamination-sensitive materials where verified chemical compatibility, full cleanability and controlled sample workflows are required. |
| Energy & Power Generation | Hot ash, slag, coke, petcoke and boiler residues where sample temperatures or abrasiveness exceed the operating range of HDPE containers. |
| Precious & Base Metals Recycling | Smelter samples, shredded e-scrap fractions, precious metal bearing slag and granulated metal residues where elevated temperatures, sharp or abrasive particles and the need for verified cleaning between high-value samples require stainless steel surfaces. |
| Laboratory & Research | Durable, fully cleanable containers for pilot-scale trials, method development and repeated-use workflows where cross-contamination must be eliminated between sample batches. |
| Food & Feed | Selected applications where stainless steel contact surfaces, validated cleaning procedures and compliance with food-contact hygiene standards are required by the process or customer specification. |

Available or application-dependent options include:
RFID makes it easier to connect the physical bucket to the correct sample, batch, line, shift or laboratory workflow. Where several buckets are handled at the same time, RFID can reduce the risk of manual errors and support traceability from sampling point to analysis.
