GWJ-4AThe Type 2 particle detector is an upgraded version developed by Tianjin Tianda Tianfa Technology Co., Ltd. based on the GWJ-4 particle detector. It uses laser light resistance method, imported high brightness laser light source, 6 channels, and can set 10 particle sizes. It is mainly used for the detection of particles and particle size distribution in large and small injections, infusions, high viscosity, colored and organic samples in the 2010 edition of the Chinese Pharmacopoeia.
GWJ-4ACompared with similar imported instruments, the particle detector has basically the same technical indicators and higher cost-effectiveness.
Technical indicators:
●Detection range: 1-500um;
●Detection channel: ≥ 2um, ≥ 5um, ≥ 8um, ≥ 10um, ≥ 12um
≥15um, ≥ 20um, ≥ 25um, ≥ 50um
≥100um；
●Pharmacopoeia channel: ≥ 10um, ≥ 25um
●Test range: 0-999999 pieces
●Sampling volumes: 0.2ml, 0.5ml, 1ml, 2ml, 5ml, 100ml
●Sampling speed: 5-80ml/min, adjustable
●Accuracy: ± 10% of the specified value
●Channel resolution: ≥ 90％
●Best test concentration: 0-10000 particles/ml (5% coincidence error)
●Relative standard deviation: RSD ≤ 2% (standard particles ≥ 1000 particles/ml)
●Mixing method: magnetic stirring
●Mixing speed: 0-2000 revolutions per minute
●Sampling and layout method: The sampling head is automatically raised and lowered, and the position can be adjusted
●Display operation: dot matrix LCD display screen, thin film buttons, can be matched with standard
keyboard
●Data output: Embedded micro printer
●Power supply: 100-264V, 50-60Hz
●Environmental temperature: 10-40 ℃
Performance characteristics:
●The performance fully meets and exceeds the requirements of the 2010 and 2005 editions of the Chinese Pharmacopoeia, with pharmacopoeia testing and anesthesia equipment, which can directly detect particle contamination in various dosages of injection solutions, sterile powders, as well as medical equipment such as drug packaging materials and anesthesia equipment;
●High precision laser sensor, stable performance, wide detection range (1-500um), not easily blocked; Double stable optical circuit ensures the accuracy of low transmittance and colored sample detection;
●Adopting advanced syringe sampling system, with high sampling accuracy and stable speed; High suction force, capable of directly detecting high viscosity samples such as iodothyrol;
●The minimum sampling volume is 0.5ml, which can directly detect small injections;
●The sampling head is automatically raised and lowered, and the sampling position can be set arbitrarily, making it convenient for various packaging and sample collection;
●High degree of intelligence, automatic processing and storage of data; Dot matrix large screen LCD display, fully Chinese menu interface, easy to operate;
●An external standard keyboard allows for easy and flexible input of drug names, batch numbers, specifications, and other information;
●The instrument adopts the magnetic stirring method commonly used in international photoresist instruments. Compared with the rotary blade stirring method, it has the advantages of uniform stirring, less generation of bubbles (photoresist instruments are easily affected by bubble interference), and improved detection accuracy and repeatability;
●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.
●Provide paid 3Q files and 3Q verification services based on user needs
