Malvern Panalytical 900nm/15ml NANOSPHERE SIZE STANDARD. LTX3900A

Malvern Panalytical 900nm/15ml NANOSPHERE SIZE STANDARD (LTX3900A) is a calibrated polystyrene sphere suspension supplied as a 15 mL dropper-tipped bottle for particle size verification and instrument calibration. The product provides monodisperse, spherical polymer particles with a nominal diameter of 900 nm and is intended for use in particle sizing techniques such as dynamic light scattering and electron microscope calibration. A Certificate of Calibration with traceability information is provided with each lot.

Key Features:

• Nominal particle diameter: 900 nm
• Container volume: 15 mL dropper‑tipped bottle
• Material: polystyrene spheres in aqueous suspension
• Concentration: optimized (approximately 1% solids)
• Particle density: 1.05 g/cm³; refractive index: 1.59 at 589 nm (25°C)
• Size distribution: ≤ 10%
• Includes Certificate of Calibration traceable to NIST

Advantages:

• Provides a certified, traceable reference for verification and calibration of particle sizing instruments.
• Monodisperse spherical particles minimize shape-related measurement variability and simplify method validation.
• Supplied at an optimized concentration for easy dispersion and colloidal stability, reducing sample preparation time.
• Packaged in a 15 mL dropper bottle for convenient, controlled dispensing during routine checks.
