Blow Fill Seal : Aseptic Filling

Système de Filling-remplissage Parentéral Aseptique : Blow Fill Seal
Unlike traditional syringe filling methods, where the body is produced independently upstream, the Blow-Fill-Seal process patented by Brevetti Angela, enables the container to be manufactered inside the SYFPAC machine right up to the insertion of the stainless steel asceptic needle at the end.

The body is then filled and a plunger is put into position. As the final step, the last part of the pharmaceutical syringe is positioned in such a way that the plunger is covered and then hermetically sealed.

This makes the pharmaceutical syringe tamper-evident even without any additional blister packaging.

The main area for filling, component assembly and sealing, is protected from contamination by a sterile air shower. Furthermore, the BFS machine has automatic internal CIP / SIP procedures to sterilise and clean the circuit where solution and process air can pass.

Pharmaceutical syringes from 0.5 ml. to 20 ml.

Only two components, the medical grade inert polymers and stainless steel needles, are in contact with the Medical excipient (drug) / vaccine / filled liquid.

Both sides of the pharmaceutical syringe (needle and the plunger) are secured with hermetic plastic covers which are formed during the molding process.
These covers protect syringe from contamination and from the plunger being accidentally pushed
