Malvern Panalytical 9.0mic/15ml POLYMER STA LTX4209A

Polystyrene latex particle size standard supplied as a 15 mL aqueous polymer suspension (LTX4209A) with a nominal diameter of 9.0 μm. Designed to provide NIST-traceable calibration for particle sizing and laser particle counters, it includes a Certificate of Calibration and Traceability to NIST. Primary uses are instrument calibration, validation and routine performance checks for particle size analyzers and laser-based counters.

Key Features:

• Nominal diameter: 9.0 μm (monosized polymer particles).
• Packaged volume: 15 mL aqueous suspension in a dropper-tipped bottle.
• Material: Polystyrene polymer particles; white/colorless suspension.
• Concentration: 0.3% solids (optimized for dispersion and dilution).
• Refractive index: 1.59 at 589 nm; particle density: 1.05 g/cm³.
• Includes Certificate of Calibration and Traceability to NIST; stability: minimum 24 months.

Advantages:

• Provides NIST-traceable calibration for accurate and auditable particle-size measurements.
• Monosized polystyrene spheres minimize shape-related measurement bias, improving comparability across instruments.
• Supplied at an optimum concentration and dropper-tipped packaging for easy handling, dispersion and dilution, with at least 24 months stability.
