Sterile Ampoules Dry Sterilization Potting

Although the ampoules in the sterile workshop are treated with water or compressed air after washing, the inner wall of the ampoules cannot be guaranteed to be completely dry. At the same time, the ampoules can only remove dust, impurity particles and slightly larger bacteria after washing. The activity of bacteria to remove biological particles; the conventional process is to place the washed ampoules at 350-450 ° C for 6-10 minutes to achieve the purpose of killing bacteria and heat sources and drying the ampoules.

There are many types of potting machines. According to the sealing method, they can be divided into fusion sealing potting machines and wire drawing potting machines. The fusion sealing potting machines are often sealed by melting the glass of the ampoule itself. The hidden danger of capillary pores is easy to occur at the sealing of the ampoule wire neck, and it is difficult to identify it during inspection. The ampoule is prone to leakage after a long time; the wire drawing potting machine is equipped with a wire drawing pliers mechanism on the basis of melting and sealing. The improvement of the potting machine avoids the shortcomings of the melting and sealing machine, and the sealing effect is ideal. The injection filling device consists of a needle, a needle holder and a needle holder seat. The needle is fixed on the needle holder and slides up and down along the cylindrical guide on the needle holder to complete the filling of ampoules. When the gas is used to increase the stability of the preparation, the inflation needle and the filling needle are installed side by side on the same needle holder and act together. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for sterile workshops and sterile rooms.

The bottle-missing and can-stop device in aseptic pharmaceutical cleanroom is composed of swing rod, travel switch, tension spring and solenoid valve. tank liquid, so as not to waste and contaminate the machine; when there is no ampoules on the toothed plate at the filling needle of the filling station due to the blockage of the ampoules in the feeding bottle or the lack of bottles, the contact between the pendulum rod and the ampoules is empty, and the pull The spring pulls down the pendulum rod until the contact of the pendulum rod is in contact with the contact of the travel switch, and the travel switch is closed. At this time, the current that contacts the solenoid valve can open the solenoid valve, causing the solenoid valve on the switch circuit to act, causing the ejector rod to lose pressure. The top action of the rod controls the injection site, so as to achieve the function of automatic stop irrigation.

Ampoule sealing methods include fusion sealing and wire drawing sealing. Fusion sealing is a form of sealing in which the rotating ampoule neck glass is melted under the heating of flame and closed by the action of surface tension. When melting under heating, the neck bottle is closed mechanically. The wire drawing seal is mainly composed of a wire drawing device, a heating device and a bottle pressing device. When the ampoule that is canned and filled with inert gas enters the position through the action of the bottle shifting tooth plate, the neck of the ampoule rests on the groove of the fixed tooth plate, and the lower part of the ampoule rests on the groove of the fixed tooth plate. On the rollers of the turbine box, and the bottom on the semicircular support.
