The equipment is mainly used for foreign body detection of drugs in the pharmaceutical industry. The detection range is ampoules, vials and oral liquids, and the applicable specifications are 1ml to 20ml. The detection items include the detection of visible foreign bodies such as drug glass debris, hair, black spots, and white lumps. The leak detection part detects the leakage of the container, and the detection theoretical accuracy reaches 0.1um; the conductivity of the medicinal liquid is required to be greater than 5us/cm (some books record that the conductivity of the medicinal liquid is greater than this value). This machine is used for the detection of insoluble and visible foreign matter in transparent injection containers in pharmaceutical factories and the tightness detection of containers.
