  • Dry laser particle size analyzer (OASIS/Dry):
    1. Dry sample testing is not affected by the limitations of media and dispersants in wet testing, and does not require any dispersants or solvents;
    2. Instantaneous dispersion and measurement, fast testing accuracy, high analysis efficiency, and only a few seconds from sample injection to result output;
    3. Easy control of dispersed energy (dispersed pressure can be adjusted between 0.1-6Bar according to material characteristics);
    4. Samples ranging from a few milligrams to several kilograms can be measured each time, ensuring representativeness of the sampling and minimizing sampling errors to the greatest extent possible;
    5. A uniquely designed decentralized system with self-cleaning function, which does not require disassembly for cleaning and can continuously test many different materials without causing cross contamination.


  • Wet laser particle size analyzer (OASIS/Wet):
    1. Wet sample wet measurement, directly measuring various suspensions or emulsions, etc;
    2. The sample pool is equipped with high and low liquid level detectors, fully automatic feeding, circulation, cleaning, and waste liquid discharge; The sample volume of the automatic monitoring system;
    3. Equipped with a 60W adjustable power ultrasonic analysis, the ultrasonic time is set according to the material, and two mechanical stirring dispersers with stepless speed regulation are used to achieve the best dispersion effect of the tested material;
    4. A stable peristaltic pump cycle is operated, and the pump speed can be infinitely adjusted according to the different samples being tested;
    5. The fully automatic system has a self-cleaning function, which avoids cross contamination between different samples;



  • Large particle materials are tested using a large range lens, while small particle materials are tested using a small range lens. Different testing lenses are selected in a targeted manner to ensure that the particle size distribution of the tested sample falls exactly at the optimal position of the selected lens range, fully ensuring the maximum resolution of the measurement and the highest accuracy and reliability of the test results;

  • The system will automatically adjust the laser beam to the corresponding output diameter based on the selected different lenses, ensuring the best diffraction intensity on the detector;

  • Fully automatic focusing system, always ensuring that the center of the laser beam, lens center, and detector center are on the same straight line, and ensuring that the detector is always in the best testing state;

  • The large amount of signals collected during testing are promptly transmitted to the computer through high-speed TCP/IP for processing, ensuring that no testing information is lost;

  • Powerful operating software with multiple report formats to choose from. Test results of different batches of samples can be compared on the same interface, and customers can customize the result output format; And it includes FDA CFR 21 Part 11 Model data;

  • The main body and casing of the instrument are all made of high-quality stainless steel, which is durable and long-lasting;
