All of Dec’s containment technologies and systems comply with pharmaceutical quality manufacturing standards and are available for aseptic operations. These can be easily integrated into existing production lines. Dec has designed various sterile isolator solutions with specific control over potential contamination sources. Operator intervention, which is the most frequent contamination cause, is eliminated.
To ensure the Sterility Assurance Level, the isolator is biologically decontaminated with VHP (Vaporized Hydrogen Peroxide), and the process equipment is sterilized with steam.
Depending on process requirements, Dec can provide both turbulent and laminar airflow isolator systems. Turbulent airflow comes in where the positive differential pressure and clean, i.e. aseptic condition and/or safe environment are maintained by using a forced ventilation system, mostly applied when handling powder with a risk of dust creation.
Unidirectional airflow systems ensure that particles are rapidly swept away from critical areas. It is therefore appropriate to use unidirectional flow in processes where mechanical equipment or material handling within the isolator produces particles that could contaminate the process, e.g. liquid filling.
Dec has furthermore developed a unique solution by using the PTS Powder Transfer System® to interface in a fully sealed way various process equipment and isolators system eliminating any risk of loss of sterility.
Sterility Testing Isolators
S-Test range systems are specifically designed to allow for sterility testing in an aseptic environment.
Fully integrated VHP systems are able to communicate with the isolator's PLC allowing for aseptic processing and decontamination as well as sterilization cycle management including aeration control to help with the removal of the VHP after the sterilization cycle. Once sterile, the samples can be membrane filter tested on the optionally integrated Millipore® Steritest system or Sartorius Sterisart®NF Units. Waste materials can be removed via the RTP or via the visor at the end of the testing procedure.
Dec's S-Test systems are available in a number of standard formats as well as tailor-made versions ranging from soft wall short-term to solid wall long-term use systems. They can feature continuous particle monitoring and airborne biological sampling methods.
These isolators are ideally suited to laboratories or where space is limited. They can be placed either adjacent to or incorporated into production lines in order to allow integrated process testing.
