Laser Particle Sizer: Particle Size Analyzer - 0.5 to 1500 µm Range - 1 Minute Measurement Cycle

Laser Diffraction Particle Sizing for Routine and Research Work

Particle size checks often hold up a production batch or a QC release, especially when an instrument needs long cleaning and frequent alignment between samples. The compact design of the ANALYSETTE 22 NeXT Micro Laser Particle Sizer addresses that delay: a complete measuring cycle, including cleaning, typically takes about 1 minute. The ANALYSETTE 22 NeXT Micro Laser Particle Sizer measures particle size distribution from 0.5 to 1500 µm in solids, suspensions and emulsions, for production control and research and development laboratories.

Key Benefits

Efficiency

With one laser, the instrument records the full measuring range in a single scan, and SOP-based automated operation keeps steps consistent between operators. See the manufacturer's ANALYSETTE 22 NeXT Micro product page for application details.

Accuracy

Reverse Fourier optics with no moving parts, Fraunhofer or Mie evaluation and continuous logging of laser output support repeatable results in line with ISO 13320. For coarser fractions, it pairs well with a vibratory sieve shaker for particle size analysis.

Safety and comfort

The laser is Class 1 per IEC 60825-1 and aligns automatically, while fast cleaning reduces sample handling between runs. SQL-based data storage keeps results revision-proof.

Key Features

• Measuring range of 0.5 to 1500 µm
• Green 520 nm laser with automatic alignment
• Single-scan measurement across the entire range
• Wet, dry and small-volume cuvette measurement with the optional units
• 16-bit converter technology
• SOP-based automated operation in NeXT Control software
• SQL-based, revision-proof data storage

Solving Common Lab Problems

How does the ANALYSETTE 22 NeXT Micro Laser Particle Sizer shorten QC waiting time? Most measurements, cleaning included, finish in under a minute.

Can the ANALYSETTE 22 NeXT Micro Laser Particle Sizer handle very small samples? The optional cuvette works with 7 to 8.5 ml of dispersion and a few milligrams or millilitres of sample, within 0.5 to 250 µm depending on the sample.

What if samples react with water or standard seals on the ANALYSETTE 22 NeXT Micro Laser Particle Sizer? Optional conversion kits with FFKM seals, a PTFE flow plate and FEP-lined hoses are available for extreme chemical resistance.
