Application of high voltage power supply in throat swab

The epidemic has continued, and nucleic acid testing has become the norm in the country. Now all parts of the country have to do nucleic acid testing every week. Nucleic acid testing requires a large number of throat swabs, most of which are flocked swabs.

The principle of the flocking swab is to use the physical characteristics of the same-sex repulsion and the opposite-sex attraction, so that the villi are negatively charged, and the object that needs to be flocked is placed under zero potential or grounding conditions, and the villi are attracted by the plant body by the different potential , accelerates to fly vertically to the surface of the object to be flocked, and because the plant body is coated with adhesive, the fluff is vertically stuck to the plant body.

In electrostatic flocking, the electrostatic generator is very important. Dalian TSM's TD2200 (60KV, 600W) high-voltage DC series is suitable for throat swab flocking. This power supply adopts digital programming, which can meet various control requirements of customers. According to the set functional requirements, it has multiple protection functions of overvoltage, overcurrent, short circuit and sparking.
