Particle analyzer GWF-8JDS

• Meets the requirements of national standards such as the 2020 edition of the Chinese Pharmacopoeia, the United States Pharmacopoeia, and GB8368 for infusion equipment. It has multiple specialized testing procedures that can directly detect the size and quantity of insoluble particles in injections, sterile powders, and infusion equipment.

• N adopts high-performance laser light source and optical energy compensation circuit to ensure the testing accuracy of various colorless and colored clear samples.

• N adopts a high-precision and high-pressure injection pump sampling system, which can set the injection volume and injection speed according to the tested sample variety and viscosity. The injection accuracy is high, meeting the detection requirements of high viscosity samples, and is not affected by factors such as location, meeting the usage requirements of different altitude areas.

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

• N can set channels arbitrarily, with an accuracy of up to 0.1 µ m, and has multiple counting methods such as cumulative and differential values to meet the requirements of particle detection in different fields.

• N has multiple built-in calibration curves, which can simultaneously meet the calibration and verification requirements of multiple standards such as the 2020 edition of the Chinese Pharmacopoeia, the United States Pharmacopoeia, and ISO21501. It can automatically calibrate channels and injection volumes to ensure the accuracy of sampling volume, particle counting, and sensor resolution, thereby ensuring the accuracy of instrument testing.

• N has a dedicated testing program for small volume injection solutions (small injections), which can set the dosage according to the labeled amount of small injections, and automatically convert it into the size and quantity of particles per container after testing, in compliance with the 2020 edition of the Chinese Pharmacopoeia and international general requirements.

• N adopts a propeller type frictionless stirrer with adjustable speed to ensure the uniformity of particle distribution in containers of different shapes, avoid particle pollution caused by friction, and improve data accuracy.

• N Color touch screen operation, Chinese input, easy and fast operation, powerful functions. It can display multi-channel test data and histogram information simultaneously.

• N has the function of preset drug and medical instrument names, with a built-in database of injection drug names and medical instrument names in the 2020 edition of the Chinese Pharmacopoeia, making operation convenient and fast.

• N has functions such as hierarchical (four level) management, data backup and recovery, storage and retrieval, and real-time recording of all device and user actions and behavior events. Meet the requirements for data audit tracking in computerized systems.
