Particle size analyzer, SALD-7500NANO

Shimadzu (Japan)

Description

Laser diffraction particle size analyzer

A precise and highly sensitive instrument designed to measure particle size distribution in the range of 7 nm to 800 nm. It is an excellent solution for research in nanotechnology and life sciences.

Features

  • Wide measurement range — from 7 nm to 800 μm, suitable for studying nano- and microparticles at concentrations from 0.1 ppm to 20 wt.%.
  • High-resolution front “Wing” detector collects scattered light up to 60°, ensuring stable and accurate measurements.
  • Damped frame isolates the optical system from vibrations and shocks, eliminating the need for frequent optical alignment.
  • Enables measurement of fine bubbles (100 nm – 60 μm) and real-time tracking of size changes.
  • Consistent measurement conditions (light source, optics, algorithm) ensure reliable data comparison across concentration ranges.
  • Optional WingSALD bio software enables quantitative aggregation analysis (mg/mL) of biopharmaceutical samples.
  • Continuous measurement function (1-second interval) provides real-time monitoring of particle distribution.
  • WingSALD II software includes automatic refractive index adjustment (LDR method), simplifying analysis even without reference data.
