Product details
GWJ-5SParticle detector
GWJ-5SThe particle detector is a new generation particle detector developed by Tianjin Tianda Tianfa Technology Co., Ltd. based on the GWJ-3/4/5 particle detector, mainly for detecting particle contamination of medical equipment such as infusion equipment, anesthesia equipment, and drug packaging materials in GB8368-2005 "Disposable Infusion Equipment". Adopting high-precision laser sensors and internationally advanced plunger pump sampling systems, it has the characteristics of wide detection range, stable performance, easy blockage, fast sampling speed, high accuracy, and strong corrosion resistance.
GWJ-5SCompared with similar imported instruments, the Type 2 particle detector has basically the same technical indicators and extremely high cost-effectiveness.
Scope of application
Particle contamination and filtration of disposable infusion equipment;
Drug packaging material testing;
Anesthesia puncture kit, centrifugal plasma separator, etc;
Precision infusion filter;
Injection testing.
Technical indicators:
Optical system: Laser photoresist method
Detection range: 2-400 μ m
Detection channels: 8 channels, with particle sizes ranging from 2 to 100 μ m that can be set arbitrarily by the user at intervals of 0.1 μ m
Sampling volume: 1.25-500ml, full volume
Sampling speed: 15-150ml/minute
Sampling volume accuracy: ＜ ±1.5 %
Best detection concentration: O~10000 particles/ml
Accuracy: ± 10% of the 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 a standard keyboard
Report format: The standard for infusion equipment provides test results, contamination index, and filtration rate; Other standards provide test results;
Data output: built-in printer; RS232 interface external computer
Database software: data storage, statistical analysis function;
Power supply: AC 100V~264V, 50Hz ± 1%, ＜ 80W ;
Environmental temperature: 10-40 ℃
Performance characteristics:
The detection range is wide and can be applied to all current medical device and pharmacopoeia testing standards, including disposable infusion set contamination, filtering out new and old standards (GB8368-1998, GB8368-2005), blood transfusion equipment, anesthesia equipment, drug packaging materials, precision infusion filters, pharmacopoeia standards, and various testing standards currently used by medical device testing centers and drug testing institutes;
The particle size of the channel can be set arbitrarily within the range of 2-100 μ m for flexible use. Users can set their own particle size to assess the samples and develop their own internal control standards, which is particularly advantageous for multi variety testing in drug research units and testing centers;
Adopting an advanced plunger pump sampling system, the sampling speed is stable, the sampling accuracy is high, and the sampling volume can be set arbitrarily to adapt to different sampling volumes. The minimum sampling volume is 1.25ml, which can meet the requirements of small volume injection of drugs. The maximum sampling volume is 500ml, which can meet the requirements of disposable infusion equipment;
For large capacity detection of disposable infusion equipment, the detection speed is fast and the detection efficiency is high, with a detection rate of 150 ml per minute;
Rich data processing functions, capable of storing blank data and pre filtered data, directly providing pollution index and filtering rate;
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;
Large screen LCD display, touch screen operation, can be connected to a standard keyboard, and data input is extremely convenient;
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.
