The New LA-950 Laser Diffraction Particle Size Analyzer

Additional information

Product web page

Retsch Technology’s LA-950 Laser Diffraction Particle Size Analyzer is the second generation of the revolutionary LA-950 system, retaining the unparalleled measurement performance of the previous version with a number of usability and sampling system upgrades. The result is a truly unparalleled system for particle size analysis for a wide range of user requirements.
A thorough redesign of a number of components has enhanced the class-leading capabilities in speed, dynamic range, accuracy, and precision. At the same time, a number of customer requests have been incorporated into the system design to make the sample system change even faster, improve sampling system accessibility, and broaden the range of accessories available.
The LA-950 is available in a number of different versions to optimize the system for specific user requirements.

Features & Benefits

Widest Measurement Range Available
The revolutionary optical system design provides the widest dynamic range (0.01-3000 µm), while still offering the lowest detection limit and best small-size performance of any laser diffraction instrument.
The long focal length also allows for the best large-particle performance available.

Unequalled Accuracy, Precision and Reproducibility
The highly refined optical system, combined with improved components and an optimized algorithm, provide unmatched accuracy, precision and resolution.

• Accuracy guaranteed to within 0.6%
• Precision guaranteed to within 0.1%
• Stability and reproducibility from unit to unit ensured with rigid optics and detector calibration.
  

Fastest Sample-to-Sample Measurement Time – 60 Seconds
Automation built into the hardware and software ensures speed, reproducibility and ease of use. Complete sample analysis sequence is completed in 60 seconds, including fill, alignment, blank, measurement, drain and rinse cycles

Most Powerful Sampling Systems Available
The modular design allows for a range of sample dispersion systems to be offered to optimize the analyzer system for the end user's requirements. Each system has been improved over successive generations to include the features required in modern particle size analysis
The standard high-output centrifugal pump, capable of suspending even the largest dense particles, includes a powerful inline ultrasonic probe for dispersion of agglomerates and a standard fill pump to automate the analysis sequence. This allows the complete sample dispersion and analysis sequence to be handled without the need for external sample preparation.
Alternative sample systems are available in different volumes, for organic solvents, and with different pump types for specific applications.

Fastest Sampling System Change
The unique measurement cell system allows up to three sample dispersion systems to be mounted simultaneously on a cell tray. Changing between sampling systems only requires the tray to be moved from one position to another, in as little as ten seconds, without removing or replacing any hardware.
Alternative designs require removal of one sampling system and replacement with the next, requiring extra storage space and need to remove cell, connect tubing, electronic changes, add dry system, align components, etc.

Yes, I would like the vendor to send me additional information about this product.
