PLANETARY BALL MILLS
A PTFE-contact milling jar for applications where chemical compatibility and the working surface are important selection factors.
A PTFE-contact milling jar for applications where chemical compatibility and the working surface are important selection factors. Use the material name PTFE when specifying the item rather than relying on a trade name alone.
The jar working surface forms part of the contact system between sample, media and mill. Material selection should balance the required mechanical action with chemical compatibility and the acceptable contribution from wear.
Chemical resistance is not a universal solvent, temperature or pressure approval. Check the sample, liquid, seals and complete jar construction together.

Compatible chemical, polymer and laboratory mixing or milling processes.
Suitability depends on the actual sample, process and analytical requirements; a listed application is not a guaranteed final-particle-size result.
Specify dimensions, support construction, closure and seal requirements, including any proposed vacuum or atmosphere operation.
State the required grade, quantities, drawings and destination when requesting a quotation. Confirm what is included, the document requirements, packing and commercial terms; no generic delivery time or universal custom capability is assumed.

Match polytetrafluoroethylene (PTFE) to the sample chemistry and the elements or residues that matter to the analysis. Then confirm the dimensions, complete loaded mass and operating arrangement against the selected mill.

The speed reference/unit and temperature sensor position are not fully documented. Speed and cumulative processing time both changed, so this is not a controlled speed-only experiment. No particle-size result was obtained. It illustrates why cooling-area and sample/jar temperatures must be distinguished.
For a polytetrafluoroethylene (PTFE) comparison, use matched sample portions and the same measurement/dispersion method. State the jar, media, mass/volume loading basis, processing schedule and contamination measurements. A change in material grade alone is not established as the cause of a result.
These anonymous records are not operating instructions. Measurement and dispersion methods are not fully specified in the test summaries; results apply to the reported samples and conditions.
Discuss a matched sample evaluationSpecify PTFE, the required dimensions and the complete jar/seal arrangement. A trade name does not define the grade, construction or operating limits of the supplied component.
Listed nominal volumes: 25mL, 50mL, 100mL, 250mL, 500mL, 1L, 1.5L, 2L, 2.5L, 3L, 4L, 5L, 10L, 15L, 20L, 25L. Check external diameter, complete lid-inclusive height, holder/clamp geometry and loaded mass. Specify dimensions, support construction, closure and seal requirements, including any proposed vacuum or atmosphere operation.
No. Allow space for media and material movement, and check the permitted loaded mass. Chemical resistance is not a universal solvent, temperature or pressure approval. Check the sample, liquid, seals and complete jar construction together. Agree the charge for the actual polytetrafluoroethylene (PTFE) jar and process.
Consider the sample chemistry, the jar working material, contamination limits and the required result. Chemical resistance is not a universal solvent, temperature or pressure approval. Check the sample, liquid, seals and complete jar construction together. Confirm the complete pairing before specifying a diameter mix or media charge.
Specify dimensions, support construction, closure and seal requirements, including any proposed vacuum or atmosphere operation. A proposed custom feature is subject to engineering confirmation and is not automatically included with a standard jar.
Membrane formulation: XQM-0.4A, 60 g in 100 mL PTFE jar, 15 h. The record documents a PTFE-jar procedure, not a particle-size or chemical-compatibility certification. The supplied jar grade, seal and part number are not identified. A material-family observation does not certify the supplied part or grade.
