04. Sterile Liquid Transfer Port (SLTP)

What's the Sterile Liquid Transfer Port SLTP System?

The Sterile Liquid Transfer Port – SLTP system is designed for the transfer of critical fluids during pharmaceutical and biopharmaceutical production. It eliminates the need for physically moving boxes and tote bags, reducing the risks associated with breakage, spillage, and product loss. This system provides a practical, safe, and simple solution for transferring large volumes of liquid between rooms while minimizing the risk of cross-contamination. With proper installation, there is no need for revalidation between product transfer processes.

SLTP offers optional purification ports and comes in customizable sizes ranging from 4″ to 8″. It can be tailored to meet specific customer requirements, utilizing standardized components such as blind holes or multiple ports. The system can be equipped with gas pipe connectors, diaphragm valves, pressure gauges, and sterilizing filters, among other accessories, to accommodate various room configurations and fulfill diverse customer needs.

Key Features of Sterile Liquid Transfer Ports

YOUTH’s sterile liquid transfer ports boast a range of features that set them apart. First and foremost is their meticulous design and construction, which ensures optimal performance and durability. The ports incorporate advanced sterility assurance mechanisms, such as double-door systems and aseptic connections, to prevent the ingress of contaminants during transfers. Additionally, YOUTH’s transfer ports are compatible with various containers and equipment, making them versatile and adaptable to different manufacturing and research processes.

Applications of Sterile Liquid Transfer Ports

Sterile liquid transfer ports find application across a spectrum of industries. In pharmaceutical manufacturing, these ports are vital for aseptic filling, sampling, and product transfers between different production areas. Biotechnology research and development laboratories rely on transfer ports for contamination-free cell culture transfers, media additions, and sample handling. Even clinical laboratories benefit from the use of sterile liquid transfer ports, ensuring accuracy and reliability in diagnostic testing.

The steps for using the fluid pass-through system (SLTP)

  1. Preparation: Ensure that the installation location for the SLTP system is ready, and all components and accessories of the system are prepared.
  2. Size verification: Select the appropriate SLTP size based on requirements and ensure it accommodates the desired fluid capacity and pipe connections.
  3. Installation preparation: Clean and sanitize the SLTP components as necessary to meet hygiene standards. Inspect and confirm the integrity and sealing of all connection parts.
  4. Installation of the SLTP system: Install the components and accessories of the SLTP system at the prepared location following the installation guide and drawings. Ensure connections are securely tightened and properly installed to ensure system stability and safety.
  5. Connect the pipelines: Connect the pipelines for the fluid to be transferred to the inlet and outlet of the SLTP system. Use appropriate fittings and seals to ensure a secure and reliable connection between the pipelines and the SLTP system.
  6. Fluid transfer operation: Start and control fluid transfer using the appropriate control devices according to the operation manual and process requirements. Ensure the system operates according to predetermined parameters and procedures.
  7. Monitoring and adjustment: Regularly monitor the operating status and fluid transfer process of the SLTP system. Make adjustments and optimizations as needed to ensure efficient and safe fluid transfer.
  8. Maintenance and cleaning: Perform regular maintenance and cleaning of the SLTP system, including cleaning and sanitizing the components and accessories of the system. Ensure system reliability and compliance with hygiene standards.

Types of Sterile Liquid Transfer Ports

Sterile liquid transfer ports come in different types, each catering to specific requirements. Passive transfer ports provide a sealed barrier, allowing transfers without breaking containment. Active transfer ports, on the other hand, utilize mechanisms such as peristaltic pumps or venting systems for more controlled transfers. Both single-use and multiple-use transfer ports are available, offering flexibility in terms of usage and cost-effectiveness. Single-use transfer ports provide the advantage of disposability, eliminating the need for cleaning and validation, while multiple-use transfer ports are designed for repeated use with proper maintenance and sterilization procedures.
