Performance features:

  •  lMeet the testing requirements of multiple national standards for medical devices such as GB8368-2018 infusion sets and the 2020 version of the Chinese Pharmacopoeia.

  •  lUsing high-performance laser light source and wide energy compensation circuit, it can directly detect various colorless and colored clear test products without using 0.9% sodium chloride as eluent, which reduces detection costs.

  •  lUsing an advanced high-precision high-pressure syringe pump sampling 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 and the accuracy is high, regardless of the viscosity and viscosity of the test product. Effects of different altitude areas.

  •  lThe sampling slit and pipeline are made of imported 316L and PTFE materials, which can directly detect special solutions such as organic solvents and oil matrices.

  •  lIt is equipped with special testing procedures for infusion sets, medicine packaging materials, anesthesia packages, etc., making various tests simpler. There are few intermediate links in the operation and the detection time is short. It is suitable for large-volume inspection, improves work efficiency, and ensures the authenticity of the inspection data.

  •  lUsing a rotary paddle-type frictionless stirrer with settable speed to ensure the uniformity of particle distribution in sample containers of different shapes and volumes, avoiding the generation of particles due to friction, and improving the accuracy of data.

  •  lAdopts large-screen LCD display, powerful functions, user-friendly interface settings, simple and clear Chinese menu, and can display multi-channel test data and histogram information at the same time.

  •  lIt has the function of presetting the names of drugs and medical equipment, and stores hundreds of injection drug names and medical equipment names in the "Chinese Pharmacopoeia", making the operation easy and fast.

  •  lPermission management, microcomputer control, high degree of intelligence, can be connected to a computer or laboratory operation platform through the RS232 interface, and has automatic data processing and storage functions.
