Eight independent positions
Process multiple formulations, compositions or control samples in parallel instead of repeatedly cleaning and reloading one large jar.
MJ-15-25SS Stainless Steel Ball Milling Jar
1. An eight-position, 25 mL-per-position SUS304 milling set developed for parallel laboratory sample processing.
2. The sample tubes are mounted at an inclined angle to increase milling energy compared with a conventional vertical planetary arrangement, making the set suitable for high-throughput material screening and comparative experiments.

Laboratory multi-station ball milling jar: Designed for efficient parallel material screening
Traditional laboratory milling often requires samples to be processed sequentially, which increases experiment time and can introduce differences between batches. The MJ-15-25SS divides the workflow into eight independent small-volume stainless steel tubes in each set. When installed in the specified MSK-SFM-15 or MSK-SFM-1 system, four sets can support simultaneous milling of up to 32 different materials or formulations under coordinated operating conditions.
Inclined tube placement
Each stainless steel tube is held at an angle. According to the supplied specification, this arrangement provides higher milling energy than a traditional vertical planetary setup.
Small 25 mL format
Suitable for early-stage screening and small sample quantities where conserving research material and increasing experimental coverage are important.
SUS304 construction
The stated SUS304 stainless steel material provides a durable metallic milling container for compatible laboratory powders and samples.
Standardized comparison
Parallel tubes help researchers compare several samples within the same milling run, reducing time-related variation between separate batches.
Modular set configuration
One set includes eight tubes and two holders. Multiple sets can be arranged according to the compatible machine configuration.

From sequential testing to parallel screening
| Evaluation point | Single-jar sequential workflow | MJ-15-25SS parallel workflow |
|---|---|---|
| Sample handling | Samples are loaded and processed one after another. | Eight independent samples can be loaded in one set. |
| Experimental comparison | Separate runs may introduce time and condition differences. | Multiple samples can be processed during the same operating cycle. |
| Cleaning frequency | One shared jar may require cleaning between every material. | Independent tubes reduce changeover between parallel samples. |
| Screening throughput | Limited by repeated runs. | Up to 32 materials are stated when four sets are installed on a compatible system. |
| Typical value | Useful for larger individual batches. | Useful for formulation screening and small-volume research. |
This comparison describes workflow differences, not guaranteed processing performance. Actual output depends on machine settings, loading, material properties and grinding media.
Typical high-throughput research tasks
Composition screening
Compare several raw-material ratios or additive levels during early-stage formulation development.
Battery materials
Prepare multiple small powder batches for exploratory cathode, anode or solid-electrolyte research, subject to contamination requirements.
Ceramic powders
Mix or mill several ceramic formulations in parallel before pressing, sintering or characterization.
Catalyst development
Screen different supports, active components or preparation conditions using independent small-volume tubes.
Mechanical alloying
Evaluate multiple metallic powder combinations where SUS304 contamination is acceptable and operating limits are confirmed.
Teaching laboratories
Allow several groups or sample sets to run within a coordinated laboratory milling workflow.
Operating workflow
Recommended preparation sequence
1. Plan the matrix
Assign each tube a sample ID and define equal or intentionally varied processing conditions.
2. Load consistently
Add the specified sample and grinding media while keeping each tube within confirmed loading limits.
3. Secure the holders
Close every tube correctly, place all tubes in the holders and install the set according to the ball mill manual.
4. Run and document
Use approved settings, monitor the cycle and record tube position, speed, time, media and sample details.
What to confirm before purchase
Sample chemistry: review corrosion, reaction and contamination risks associated with SUS304 stainless steel.
Grinding media: select material and size according to the sample, target particle size and acceptable contamination.
Processing method: state whether milling is dry or wet and identify any solvent used.
Batch loading: confirm the permitted sample and media charge rather than filling to the nominal 25 mL volume.
Supply scope: verify tubes, lids, holders, seals, media and any adapters in the formal quotation.
MJ-15-25SS FAQ
How many samples can one MJ-15-25SS set process?
One set contains eight independent 25 mL tubes. The actual usable sample charge is lower than the nominal tube volume because space is required for grinding media and movement.
How can the system process 32 materials?
The specification states that four eight-position sets can be used on a compatible MSK-SFM-15 or MSK-SFM-1 configuration: 4 × 8 = 32 samples. Confirm the exact machine setup before purchase.
Why are the stainless steel tubes inclined?
The inclined arrangement changes the motion of the media and sample. The product sheet states that it provides higher milling energy than a traditional vertical planetary ball mill arrangement.
What is included in one set?
The stated configuration includes eight SUS304 tubes measuring Ø26 mm × 57 mm and two ball mill jar holders. Confirm lids, seals, fasteners and media in the quotation.
Will SUS304 contaminate the sample?
Any metallic milling container can contribute wear-related contamination depending on material hardness and operating conditions. If iron, chromium or nickel contamination is unacceptable, discuss an alternative jar or media material.
