We offer automatic injectable Vial Liquid Filling with vacuum stoppering
systems. These are available in very compact models and requires less
space. Further, these machines are specifically designed for filling,
Stoppering and Sealing for Small Batches / R&D Purpose. This machine
basically performs three operation:

• Filling


• Rubber Stoppering


• Vial Sealing

Further it can also be used for both Full & Half Stoppering.

Application:

The vacuum stoppering unit is typically used to insert and seat stoppers - or plunger rods - in unit dose syringes
Other application it is used in includes evacuation glass tubes sealed with stopper on both ends

Construction:

• The vacuum stoppering chamber consist of stainless steel vacuum chambers with an air-driven transfer punch plate assembly & separate control box


• The latter automatically controls the process in the chamber


• During operation the loaded syringe rack is put in the chamber, the transfer punch plate is moved by a short stroke sufficient to seal the stopper to the syringe; a vacuum is reached; and then released


• The venting of the chamber restores atmospheric pressure creating a pressure differential between the top and bottom of the stopper,? thus providing a final seating of the stopper in the syringe.
