Laser diffraction particle size analyzer Winner2018

for environmental analysisfor quality controllaboratory

Overview
Winner2018 Basic is a fully automatic wet laser particle size analyzer based on Mie scattering, designed for rapid and repeatable granulometry of narrow-distribution samples. Measurement range: 0.1–450 μm. The instrument supports one-key SOP operation and is suited to research institutes, university labs, R&D centers and quality control departments.

Applications

• Metallurgy: metal oxides (alumina, aluminium hydroxide, zinc oxide, iron oxide, manganese oxide, lead oxide, etc.)
• Non-minerals: calcium carbonate, talc, kaolin, diatomite, graphite, mica, nepheline, pyrophyllite
• Chemicals: pigments, conductive pastes, fillers, dyes, paints, resins, plastic powders, synthetic rubber, photosensitive materials, toner, carbon black, inks, flame retardants, fluorescent powders, foaming agents, silica, microsilica, papermaking additives
• Agrochemicals: seed coatings, suspending agents, pesticides, herbicides
• Abrasives: silicon carbide, silicon nitride, emery, corundum, micron powders
• Energy & environment: coal-water slurry, power plant desulfurization slurries, water quality and dust monitoring

Advantages

• One-button fully automatic operation: SOP sequence automates water intake, degassing, dispersion, measurement, cleaning and data processing to reduce operator error.
• Integrated wet dispersion: ultrasonic (40 kHz / 60 W) + mechanical stirring (0–3000 rpm) with optional circulation (8 L/min) for consistent dispersion and reduced re-aggregation.
• Advanced optical design: Winner patented concentrated light Fourier transform and dual-spectrum optical path for wide dynamic range without lens-aperture constraints.
• Automatic optical alignment: precision hybrid stepping motor provides micro-motion centering down to 0.1 μm for stable, repeatable results.
• Automatic cuvette cleaning: ultrasonic cleaning at the sample window reduces manual maintenance and extends component life.
• Free fitting algorithm: original unconstrained fitting better reflects true particle size distributions.
