System Description

The Alpha XT system is a proprietary Alpha port that allows docking the beta flange and opening the alpha door without the gloved entry of the operator into the isolator chamber.

Features

Operation solely from the non-sterile (operator) side
Optional funnel actuator to engage/disengage a funnel into component delivery position
Built on La Calhene's 190 alpha port but adaptable to any other alpha port manufacturer
Minor modifications to the alpha port with no impact on the port's door interlock functionality
Separate actuators for the door locking, door opening and funnel positioning functions
Positive position lock of the alpha door in the open position
Positive position lock of the funnel in the engaged and the disengaged positions
Clean aseptic zone design compatible with wash down operations and VHP decontamination
Leak tight construction
Modular design is easily incorporated in new isolator systems or retrofitted into existing installations

Specifications

Nominal port size: 190mm, 270mm, 350mm, 460mm
Adaptable to La Calhene and CRL alpha ports
Alpha/Beta door interlock functionality: unaffected
Alpha door positive lock in the open position
Alpha door rotation: 90 degrees
Funnel rotation: 90 degrees
Configurable for right hand and left hand operation
Orientation: Operable from vertical to 45 degree inclination
Compatible with wash down operations
Compatible with VHP decontamination
Leak tight: Ammonia leak test at 250 pascal internal pressure.
Funnel configuration: As required by the application

Advantages & Applications

Alpha XT Advantages

All docking operation a are conducted from the operator side of the isolator
Manipulation of the delivery funnel is conducted from the operator side of the isolator
Funnel is precisely positioned concentric to the alpha port inside diameter

Alpha XT Applications

Transfer of sterile components from a BetaBag directly into the vibratory bowl of the filling line without the operator entering the isolator chamber.
Transfer of sterile components from a tank directly into the vibratory bowl of the filling line without the operator entering the isolator chamber. See Beta NR-HP system for details.
Transfer of sterile components through the bulkhead of a class 100 suite.

Beta NR-HP Application

The Alpha XT permits docking a tank containing cleaned and sterilized stoppers and featuring a beta flange without operator entry into the isolator system. To facilitate the docking process, the tank could include DDP's Beta NR-HP flange which, by virtue of its NR flange incorporating DDP's proprietary NR Technology, permits rotation of the beta flange without rotation of the tank.

Retrofit of existing systems

The Alpha XT's modular design and flexibility in configuration make it conducive to retrofit of the component introduction system of existing filling lines to achieve the elimination of operator entry into the isolator chamber during transfer operations.
