LBT-1301 Fully Automatic Laser Particle Size Intelligent Analyzer

Description

Product Introduction

Graphite, photosensitive materials, fuels, ink, metallic and non-metallic powders, calcium carbonate, kaolin, coal-water slurry, aluminum‑silver paste, manufactured sand, and other powdered materials.
Product Features:

★Optical Path Design: Employing convergent-beam Fourier transform measurement technology, the instrument achieves a wide measurement range even at a very short focal length, effectively enhancing its resolution. A unique high-density detector array delivers robust performance in measuring small particles, enabling the LBT-1301 to provide reliable, seamless measurements across the entire size range.

★ Fully Sealed Fiber‑Optic Semiconductor Laser: The LBT‑1301 employs a highly stable, long‑life, fully sealed fiber‑optic semiconductor laser. Its outstanding stability ensures reliable test repeatability.

★ Fully Automated Testing: Truly fully automated—your only task is to load the sample; no interference, and no manual data selection required.

★ Ultrasonic Dry‑Boil Protection: Through dedicated research and development, the LBT‑1301 features ultrasonic dry‑boil protection, preventing damage to the ultrasonic transducer when no water is present.

★ Adjustable ultrasonic power: To accommodate the dispersion requirements of various samples, the LBT-1301 offers adjustable ultrasonic power ranging from 0 to 20 milliwatts.

★ Dust‑proof and Shock‑resistant Design: The instrument features a fully sealed enclosure, significantly extending the service life of its internal components. Its unique shock‑absorbing structure effectively mitigates external vibrations, ensuring more stable and reliable test results.

★ Enhanced Corrosion‑Resistant Design (Optional): Depending on the customer’s specific requirements, the unit can be equipped to resist acids, alkalis, oils (including all solvent oils), and organic solvents such as acetone, phenol, n-hexane, and other organic solvents.

★ Automatic Optical Path Alignment: When minor optical path deviations occur due to replacement of the sample window, the instrument can automatically adjust the optical path.

★ Unique Micro‑Volume Circulation System: The entire dispersion circulation system has been optimized, allowing tests to be conducted with as little as 120 mL of dispersant, truly enabling micro‑volume circulation testing. The optimized design ensures that no residual waste liquid remains after draining, thereby guaranteeing the accuracy of subsequent test results. (Micro‑volume testing is available as an optional feature.)

★ Bubble‑free design: The innovative design ensures that no bubbles enter the sample window during testing, eliminating bubble‑induced interference.

★ Residue-Free Design: The instrument’s piping and drainage system have been optimized to ensure no liquid remains in the tubing or within the circulation pump, thereby preventing any interference with subsequent test results.

★ Sample Window Quick-Change Mechanism: A newly designed quick-change mechanism makes replacing the sample window faster and more convenient.
