Malvern Panalytical 1.112mic/15ml POLYMER STANDARD LTX4011A

Polystyrene polymer (latex) particle size standard LTX4011A (mean diameter 1.112 µm) supplied as a 15 mL suspension for instrument verification and routine validation. It provides a monodisperse, certified-size dispersion for verification of particle-sizing systems including dynamic light scattering (DLS) and other sizing techniques used in quality assurance and instrument performance checks. The formulation is supplied at 1% solids (w/v) in 15 mL and is optimized for easy dispersal and colloidal stability; dispersions can be stored at room temperature with storage lifetimes of months or years.

Key Features:

• Particle size: 1.112 µm (mean diameter).
• Volume: 15 mL suspension.
• Material: polystyrene latex (polymer) monodisperse spheres.
• Concentration: 1% solids (w/v) in 15 mL.
• Manufacturer part code: LTX4011A.
• NIST-traceable / certified-size dispersion.

Advantages:

• Enables objective verification and routine performance checks of particle-sizing instruments (for example DLS), supporting instrument validation workflows.
• Monodisperse, near-spherical polystyrene particles provide an unambiguous sizing reference and improve measurement reproducibility.
• Supplied as a 1% solids in 15 mL formulation optimized for easy dispersal and colloidal stability, simplifying sample preparation and handling.
• Dispersions can be stored at ambient temperature for months or years, aiding routine laboratory use and verification scheduling.
