100nm-1000μm is a separate size-range option and does not mean that any single diameter within the range can be selected. Only a 1g package is listed for this option.
Click a category button to switch groups. Each group shows 1–9 rows.
“—” indicates that the source list does not include that package option. The complete variant name combines PS microsphere powder, particle size and package weight. Example: PS Microsphere Powder_100nm_1g.
Check the particle size and package weight. Use a balance with suitable precision and clean tools to weigh the quantity required for your experiment, minimizing powder dispersal and cross-contamination.
Select the medium and dispersion conditions for your experiment. Record the sample mass, medium quantity and treatment process. Confirm solvent compatibility, sonication and shaking conditions according to the product instructions.
Reseal promptly after use to avoid moisture and contamination. Follow the bottle label and supplied instructions for storage temperature, shelf life and other conditions.
Provide PS microsphere powder, particle size, package weight and the required number of packages. Example: PS Microsphere Powder_100nm_1g, quantity: 2 packages.
If you need particle size distribution, batch test documentation, surface properties or dispersion suitability information, confirm the documentation for the selected variant before purchasing. Specify the intended medium and experimental application.
Select a size category. The left column shows the particle size, while the 1g and 2g columns show their respective retail prices. Each package option is a separate product; select the required package weight.
This row retains the size-range designation from the source list and is a separate option. It should not be treated as any single diameter within that range. If a specific diameter is required, select the corresponding individual nominal size from the table.
The products on this page are supplied by powder mass and have no dispersion concentration. When preparing a dispersion, record the actual sample mass, medium quantity and preparation method.
Follow the label and instructions for the powder product itself. Powders and dispersions are different product forms; confirm the medium, treatment method and storage requirements separately.
For product selection, quotations or bulk orders, provide the particle size, package weight, required quantity and experimental application.
