GWF-7JA Particle Analyzer/Particle Detector

Performance characteristics:

Using high-performance laser light sources and light energy compensation circuits, various colorless and colored clear samples can be directly detected without the need for 0.9% sodium chloride as eluent, reducing detection costs.

■The channel can be freely set within the range of 1-500 μ m, with the ability to inject samples of any volume above 0.2 ml. It meets the testing requirements of multiple national standards for medical devices such as GB8368-2005 and the 2020 edition of the Chinese Pharmacopoeia, and is suitable for various experimental methods.

■Adopting an advanced high-precision high-pressure injection pump injection system, the sample injection volume can be set by oneself, and the injection speed can be set according to the viscosity of the sample; The injection speed is fast, the accuracy is high, and it is not affected by the viscosity of the sample and different altitude areas.

■There are specialized testing programs for infusion sets, drug packaging materials, anesthesia kits, etc., making various tests more convenient. There are fewer intermediate steps in the operation and shorter detection time, making it suitable for detecting large volume samples, improving work efficiency, and ensuring the authenticity of detection data.

■Adopting a controllable rotational speed rotary slurry frictionless stirrer ensures the uniformity of particle distribution in sample containers of different shapes and volumes, avoiding the generation of particles due to friction and improving data accuracy.

■Adopting a large screen LCD display with powerful functions and user-friendly interface settings, the Chinese menu is concise and clear, and can simultaneously display multi-channel test data and histogram information.

■It has the function of presetting drug and medical instrument names, storing hundreds of injection drug names and medical instrument names from the 2020 version of the Chinese Pharmacopoeia, and is easy and fast to operate.

■Microcomputer control, high degree of intelligence, can be connected to computers or laboratory operation platforms through RS232 interface, with automatic data processing and storage functions.
