National Science and Technology Innovation Fund Project
GWJ-16The Type 2 Particle Detector is an upgraded version developed by Tianjin Tianda Tianfa Technology Co., Ltd. based on the GWJ-5 Particle Detector. It uses laser light resistance method, imported high brightness laser light source, 16 channels, and can set nearly 5000 particle sizes. It is mainly used for the detection of particles and particle size distribution in large and small injections, infusions, high viscosity, colored and organic samples in the 2010 edition of the Chinese Pharmacopoeia. It adopts high-precision laser sensors, with a wide detection range, stable performance, and is not easily blocked, making it convenient for users to maintain themselves. Different specifications of sensors can be replaced; And it adopts the internationally advanced precision plunger pump sampling system, which has the advantages of adjustable sampling volume, high sampling accuracy, not affected by the viscosity of the sample, and strong corrosion resistance.
GWJ-16Compared with similar imported instruments, the particle detector has basically the same technical indicators and higher cost-effectiveness.
