Brief introduction:
Gwj-8 type insoluble particle detector is an advanced type developed by our company on the basis of GWJ- 5 type particle detector. It can set nearly 5,000 particle sizes, mainly for the new generation of particle detector of the 2015 edition of Chinese pharmacopoeia for the detection of particle size and particle size distribution of small-sized injection, infusion, high-viscosity, colored and organic samples. The high precision laser sensor has wide detection range, stable performance and is not easy to block. It is convenient for users to self-maintain and can replace sensors of different specifications. In addition, the precise plunger pump sampling system is adopted, which has the characteristics of adjustable sampling volume, high sampling precision, free from the influence of viscosity and strong corrosion resistance.
Compared with similar imported instruments, GWJ-8 type insoluble particle detector has basically the same technical indicators and extremely high cost performance.
Features:
1. the performance fully meets and is superior to the requirements of the 2015 edition of the Chinese pharmacopoeia, with built-in standards for the detection of pharmacopoeia, anesthesia apparatus and infusion apparatus, and can be directly used for the detection of contamination filtration rate of various volumes of injection, sterile powder and medical apparatus particle detection; Wide detection range, 1 ~ 500um; Built-in calibration curve, particle size distribution detection function; Can be in 1.2 ~ 100μ Within the scope of m, thousands of particle diameters are set by users for particle detection and analysis, and their own internal control standards are developed. In particular, it has great advantages for multi-variety detection of drug research units and testing centers.
2. High resolution >95%, better than the requirements of Chinese pharmacopoeia;
At the same time, according to the United States pharmacopoeia and ISO21501 for the resolution and various indicators of calibration instruments;
3. Precision syringe sampling system, sampling accuracy is better than 1%;
The minimum sampling volume is 0.2ml;
4. The magnetic stirring method (bottom stirring) commonly used by the upper photoresist method is adopted. Compared with the top stirring, it has the characteristics of uniform stirring and not easy to generate bubbles;
5. Close the testing room, the sampling head can be automatically raised and lowered, and the lifting position can be set at will. The convenient and flexible testing room structure can be used for taking and lofting samples.
6, large screen LCD display, touch screen operation, can be connected to the standard keyboard, data input is very convenient;
7. Easy to clean up and remove blockage of sensors;
8, the full voltage range of 100 ~ 264V design, can overcome the fluctuations of the power grid, the instrument without external stable voltage power supply.
