GWJ-8 Particle Detector
The GWJ-8 particle detector is an upgraded version developed by Tianjin Tianda Tianfa Technology Co., Ltd. based on the GWJ -/5 particle detector. It uses a laser photoresist method, imported high brightness laser light source, and 8 channels. The new generation particle detector can be set with nearly 5000 particle sizes, mainly for detecting particles and particle size distribution of large and small injections, infusions, high viscosity, colored and organic samples in the 2010 edition of the Chinese Pharmacopoeia. The high-precision laser sensor used has a wide detection range, stable performance, and is not easily blocked; Convenient for users to maintain themselves and can replace sensors of different specifications; And it adopts the internationally advanced precision plunger pump sampling system, which has the characteristics of adjustable sampling volume, high sampling accuracy, not affected by the viscosity of the sample, and strong corrosion resistance.
Compared with similar imported instruments, the GWJ-8 particle detector has basically the same technical indicators and extremely high cost-effectiveness.
Performance characteristics:
The latest model in 2009 fully meets and exceeds the requirements of the 2010 edition of the Chinese Pharmacopoeia in terms of performance. It is equipped with pharmacopoeia, anesthesia equipment, and infusion equipment testing standards, and can directly perform particle contamination filtration rate testing for various dosages of injection solutions, sterile powders, and medical equipment;
Wide detection range, 1-500 μ m; The instrument has a built-in calibration curve and the ability to detect particle size distribution; Users can set thousands of particle sizes within the range of 1.2-100 μ m for particle detection and analysis, and develop their own internal control standards, which has great advantages for multi variety testing in drug research units and testing centers;
Has high resolution,>95%, better than the requirements of the Chinese Pharmacopoeia; At the same time, instruments that can be calibrated for resolution and various indicators according to the United States Pharmacopeia and ISO21501;
Advanced precision syringe sampling system with sampling accuracy better than 1%; The minimum sampling volume is 0.2ml;
Adopting the magnetic stirring method (bottom stirring) commonly used in international photoresist instruments, compared with top stirring, it has the characteristics of uniform stirring and less generation of bubbles;
Closed testing room, automatic lifting of sampling head, adjustable lifting position; Easy to take and layout; Flexible testing room structure, capable of directly testing various dosages of injections (1-500ml bottles, bags, etc.);
Large screen LCD display, touch screen operation, can be connected to a standard keyboard, and data input is extremely convenient;
Easy to clean and remove blockages from sensors;
Designed with a full voltage range of 100-264V, it can overcome power grid fluctuations and the instrument does not require an external voltage regulator.
