Description

With its intuitive operation, sterile connections can be to be carried out in a simple three-step operation, even in an unclassified environment, without compromising the sterility of the fluid paths.
Key design features such as the anti-actuation tabs and tamper-resistant protective cap give end users more confidence in operation and security of supply.
The Kleenpak Presto sterile connector brings enhanced levels of quality assurance with 100% inspection at point of manufacture that allows device traceability, as each device has its own serial number. The manufacturing process of Kleenpak Presto sterile connectors brings an enhanced level of quality assurance, with the use of an automatic vision system that ensures the absence of defects in the membrane and membrane welding.
Available in a variety of sizes – 6.35 mm (¼ in.), 9.53 mm (⅜ in.), 12.7 mm (½ in.), 15.8 mm (⅝ in.), 19 mm (¾ in.) hose barb, and 12.7 mm (½ in.) sanitary connection – the Kleenpak Presto sterile connector can be used in upstream processing, downstream processing, and formulation and filling. Made from Bisphenol-A (BPA) free Polyethersulfone (PES) the Kleenpak Presto sterile connector is compatible with a wide range of process fluids and solvents.

Testimonials
The Pall Kleenpak Presto sterile connector is a welcome addition to the space of aseptic connections in the bio-pharmaceutical industry. It overcomes some of the major downsides of other connection technologies with unique attributes and error-proofing designs.
- The tamper-proof cover ensures that the critical membrane surface is not disturbed, unlike alternative devices with covers which can be removed and replaced.
- The pull tabs include a rigid “guide track” which ensures the operator pulls the tabs perpendicular to the device. This avoids many possible failure modes that are present with competitor’s devices.
- The twist-to-lock mechanism provides visual indication of a successful connection, but also reduces the force required to pull the membranes because the full compressive force between the two halves is not engaged until after membrane removal and twisting. The twisting mechanism is intuitive and does not add significant complexity to the connection.
The Kleenpak Presto sterile connector is my first recommendation for connection of single-use systems because none of the other devices on the market combine all of these attributes with a compact form-factor. The extensive validation data provided by Pall reduced the resources needed to implement these devices and provides assurance of their ability to maintain aseptic fluid pathways in our manufacturing processes.

Easy-to-Use Operation
Preparation

Remove the protective cap from both connectors by pulling the tab in the direction shown above.
1. Connection of the devices

Connect the two devices together ensuring the membranes are in the same direction and the blue tabs lock together – an audible click is heard.
2. Membrane removal

Remove the tabs by pulling both tabs at 90 degree to the connector assembly.
3. Actuation

Actuate the assembly by turning each device into each other as shown above.
The connection is confirmed by the audible click and also the alignment of the colors as seen above.
