Anton Paar Laser Diffraction Particle Size Analyzer: Litesizer DIF — Particle Size Analyzers

Manufacturer: Anton Paar — Austria

Overview

The Litesizer DIF series offers advanced particle sizing from 10 nm to 3.5 mm. Drawing on nearly 60 years of laser diffraction expertise, this laser diffraction particle size analyzer offers a best-in-class optical setup with powerful 10 mW and 25 mW lasers and the widest range of detected diffraction angles from 0.01° to 170° on the market. The Kalliope software simplifies particle sizing with the laser diffraction particle size analyzer; no extensive training is required and measurements are performed with just three clicks. The Quick-Click system allows easy switching between dispersion units, minimizing errors. Safety features for both liquid and dry dispersion ensure effortless, secure operation. The laser diffraction particle size analyzer's robust metal housing and the isolated optical bench deliver reliability everywhere: from harsh environments to high-tech laboratories. Fueled by our pioneering legacy, this is next-generation laser diffraction technology – the Litesizer DIF series: From First to Best.

Particle Sizing in any Environment

Anton Paar's laser diffraction particle size analyzer is suitable for heavy industries, with high-quality components inside and out. A sturdy metal housing encases durable optical elements. The laser diffraction particle size analyzer is built to endure harsh environments. No dust or powder can penetrate the optical bench of the instrument, and the inside of the instrument is isolated from possible direct vibrations at the production site. All of this means savings on upkeep and repair costs.

Less Investment, Saved Bench Space – Compatibility Across the Board

Compatibility of dispersion units with Anton Paar's Litesizer DIA and Litesizer DIF instruments reduces investment costs and lab space usage. On top of this, all Litesizer instruments, including the Litesizer DIF laser diffraction particle size analyzer, can be operated using a single PC with the Kalliope software installed.

Kalliope: The Benchmark Software for Particle Sizing

With Kalliope, users of the laser diffraction particle size analyzer can get started quickly via the one-page-only workflow (setting parameters, acquiring, and working with results). Additionally, the QC mode offers consistent, reliable measurement results by customizing user management and locking delicate settings. The laser diffraction particle size analyzer in QC mode provides simple feedback if your product is within your defined limits. This means results in just three clicks and less training for new users. In addition, a pharma option with data security functions, user management, and audit trails is included, making Kalliope compliant with the US FDA's 21 CFR Part 11.

Efficient Dispersion, Maximum Safety

Litesizer DIF's Quick-Click feature connects the dispersion units in just one move – no hassle with cables, tubes, or pipes. The obscuration level indicator allows monitoring of the sample amount while adding it to the laser diffraction particle size analyzer, ensuring the right amount from the start. The Dry Jet dispersion unit has a suction check and built-in dust cover to minimize the risk of powder spread. The Liquid Flow unit automatically checks for sufficient liquid before sonication, preventing overheating. A dedicated module with high chemical resistance is available for aggressive liquids. The Liquid Flow Imaging unit combines laser diffraction and dynamic image analysis, adding shape parameters of particles from 5 µm in size.

On Quality, We Lead the Way

Litesizer DIF is the perfect tool for particle analysis due to its high-quality manufacturing. It features high-grade hardware, empowering the instrument to collect superior raw data. The laser diffraction particle size analyzer enables users to measure a broad range of samples, covering particle sizes from 0.01 µm to 3,500 µm with a single analyzer – without the need for additional investment.

A Decade of Confidence: 10-Year Laser Warranty

Each Litesizer DIF is built around a high-performance laser system engineered for decades of reliable operation. To support this, Anton Paar offers a 10-year laser warranty – a commitment that goes far beyond industry standards. This reflects our promise that this laser diffraction particle size analyzer's core optical performance will keep delivering consistent results, year after year, no matter the demands of your application.
