Application of Closed Transfer Technology - Split butterfly valve and RTP
In the fields of pharmaceutical industry, biological industry, food, nuclear and others, we often encounter that the input and output of some special materials need to be carried out in a specific confined space to avoid contacting with the external environment. For example, sterile materials, highly allergenic materials and toxic materials.
At present, Geevo company has two transfer methods, which can meet above requirements for users.
A. Split butterfly valve, also called ab valve
Adopts split butterfly valve technology. it is made up of an active valve and a passive valve. Active valve is usually fixed in the need for frequent feed in and our of the port, and the passive valve can move, which connected to the transferable container. The transfer of material from one container to another container is being carried on sealing condition, and the sterile material transfer process guarantees the sterile situation won't be destroyed or avoid being spread of the powder, toxic materials in the container.
Interlock function: Only active valve and passive valve are mated completely, then can open the transfer channel.
When the transfer channel is opened, the passive valve cannot be disconnected.
PROCESS:
B. Rapid Transfer Port (RTP)
Rapid Transfer Port (RTP) is a double-door system, containing our transfer technology.
This system consists of two basic parts, alpha part and the beta assembly part.
The alpha part is normally mounted to the chamber of Isolator or glovebox and the Beta assembly part is mobile and connected to a container, bag or process component. When the two assemblies are mated, sterile or hazardous materials can be rapid l transferred in and out of the glovebox withour breaking containment, while maintaining the safety of the operators.
RTP is often used for material output and transport or for the removal of solid waste from the chambers.
Interlock System
prevent the improper operation of the transfer port which can compromise the containment and sterility of the barrier/isolator.
The interlocks are incorporated into the Alpha part and interface with the alpha port door handle to prevent:
- The Alpha door cannot be opened if the Beta container is incorrectly connected or placed.
- When the Alpha door is opened, the Beta container cannot be disconnected.
