Introduction: GWJ-5S particle detector is a general-purpose testing instrument in the series of particle detectors produced by Tianda Tianfa Technology Co., Ltd. that meets the requirements of GB8368 "Disposable Infusion Sets" and the requirements for particle pollution and filtration detection of various medical devices. It is mainly aimed at the requirements of large sampling volume, large particle size, and rapid detection, and also takes into account the requirements of the 2020 edition of the Chinese Pharmacopoeia for the detection of insoluble particles in injections. Mainly applicable to: "Disposable Infusion Sets" standard; "Chinese Pharmacopoeia" injection insoluble particle detection; pharmaceutical packaging materials, medical device particle pollution, filtration detection; water, organic solution and other particle pollution detection. Features: 1. Wide testing range, applicable to all current testing standards for medical devices and pharmacopoeia, including pollution and filtration standards for disposable infusion sets (GB8368-2018), blood transfusion apparatus, anesthesia apparatus, pharmaceutical packaging materials, and precision infusion filters, old and new Various testing standards currently adopted by medical device testing centers and drug testing centers such as standard push, pharmacopoeia standards, etc. 2. The particle size of the channel can be arbitrarily set to detect the particle size within the range of 2-100μm. It is flexible to use. Users can set the particle size by themselves to assess the test products and formulate their own internal control standards, especially for drug research units and testing centers. Multi-species detection has great advantages. 3. Using advanced plunger pump sampling system, the sampling speed is stable, the sampling accuracy is high, the sampling volume can be set arbitrarily, adapt to different sampling volumes, the sampling volume is as low as 1.25ml, which can meet the requirements of small-volume injections of medicines: sampling The volume is up to 500ml, which can meet the requirements of disposable infusion devices. 4. For the large-capacity detection of disposable infusion devices, the detection speed is fast, the detection efficiency is high, and the detection is 150ml per minute. 5. Rich in data processing functions, it can store blank data and data before filtering, and directly give the pollution index and filtering rate. 6. The magnetic stirring method (lower stirring) commonly used in the international photoresist method is adopted. Compared with the upper stirring, it has the characteristics of uniform stirring and not easy to generate air bubbles. 7. The detection room is closed, the sampling head is automatically raised and lowered, and the lifting position can be set arbitrarily; it is convenient to take and set out. 8. Large-screen LCD display, touch screen operation, can be connected to a standard keyboard, data input is extremely convenient. 9. The design of the full voltage range of 100-264V can overcome the fluctuation of the power grid, and the instrument does not need an external regulated power supply. Technical parameter: Optical system: laser photoresist method Detection range: 2～400μm Detection channel: 8 channels, the particle size can be arbitrarily set by the user at intervals of 0.1 μm in the range of 2 to 100 μm Sampling volume: 1.25～500ml, full volume Sampling speed: 15～150ml/min Sampling volume accuracy: <±1.5% Detection concentration: 0～10000 grains/ml Accuracy: ±10 % of specified value Repeatability: RSD < 2 % (particle count > 1000 particles/ml, 5ml sampling) Display operation: 5.7 inch LCD touch screen operation; can be equipped with standard keyboard Report format: test results, pollution index and filtration rate are given for infusion equipment standards; test results are given for other standards; Data output: built-in printer Database software: data storage statistical analysis function; Power supply: AC 100v～264V, 50Hz±1%, ＜80W Ambient temperature: 10～40 ℃
