Rapid Transfer Ports (RTPs)
Find out how the 
can transform your processes
The 
rapid transfer system is a patented design. The design takes rapid transfer technology to a new level of performance. The alpha and beta flanges are fully compatible with the La Calhène DPTE® range of alpha and beta flanges.
The alpha ports have the same fixing diameters as the DPTE® alpha ports.
The security mechanism is 100% interlocked with the following automatic functions:
- The alpha port cannot be opened without a beta part connected.
- The alpha port cannot be opened if a beta flange is docked without the beta door.
- The beta cannot be detached from the alpha door whilst the alpha door is open.
- It is impossible to “cheat” the interlocks from the outside of the enclosure.
- No parts moving parallel to the axis of the alpha flange so no fragile membranes are used for sealing the security mechanism.
-
Standardised design. The security mechanism is standard for all diameters.
- Ergonomic design of Alpha door handle for easy operation when wearing neoprene or hypalon gloves
- Careful choice of materials for all components for minimum weight and optimum mechanical reliability.
- Designed for biodecontamination.
Leak tightness:
- 1.6 pa/min for a test pressure of 500 Pa ( for all diameters of both alpha and beta).
Surface finish:
- Better than 0.6 Ra (1.6μm compliant to ISO 1302).
Regulatory compliance:
- Conforms with cGMP regulatory requirements for transfer devices.
- Guaranteed zero contamination when used for transfers between a Grade A aseptic processing environment in a grade D background.
- Suitable for use in a non-classified environment.
- Suitable for use on BSL3 and BLS 4 enclosures.
- Suitable for use of OEB 5 hazardous compounds
Range of normal operating conditions:
- Temperature +16 ̊C to +30 ̊C
- Normal operating pressure range +/- 500Pa.
- Maximum permissible pressure = + 3800Pa RH 10 to 80% @ 25 ̊C
Autoclaving:
- 131 ̊C at 30 mbars max for stainless steel, aluminium autoclavable containers and autoclavable versions of the alpha port.

Performance
- Leak tightness conforms to ISO12469 and ISO10648-2
- TAMPER PROOF Interlocks:
- Alpha cannot be opened without beta
- Beta cannot be removed when alpha is open
- Cannot dock and open with a beta without beta door
- Safety button on door handle.
- Improved control of “ring of concern” with new seal design.
- Good ergonomics for ease of use:
- Low docking torque
- Handle can be placed in 4 different positions.
- Fully interchangeable parts.
- Major parts can be changed without dismantling the alpha flange.
- All beta flanges have wear limit indicators
Advantages of RTP
Alpha
-
Direct acting interlocks
The beta flange acts directly on the main-shaft of the security mechanism to ensure a positive, precise and reliable action.
-
No fragile membranes on moving parts
Use of O-ring seals only to guarantee long term reliability of leak tightness.
-
No damage to the beta parts
The innovative design of the security actuating mechanism in the alpha port ensures that no damage to the beta door occurs during the connection.
-
Ergonomic design
The handle can be positioned either horizontally or vertically
-
Reduction of potential contamination
with new lip seal design.
-
Reduced docking torque
from new design of locking ramps
-
Easy to clean, smooth, high quality finish
Finishes conform to ISO 1302 and smooth accessible surfaces for good cleanability. Crevasse free design, suitable for use in aseptic environments. Drain holes to prevent retention of cleaning fluids.
-
Design suitable for surface bio-decontamination
processes such as vaporised hydrogen peroxide
-
Bio-decontamination compatible materials for all components
Our ports are compatible with VHP, Chlorine dioxide, Formaldehyde etc. and non- oxidising cleaning agents such as Trigene and acid based oxidising disinfection products such as Virkon
-
Maintainability
Security mechanism, hinge and alpha door designed for easy maintenance and replacement without the need to dismantle the flange from the isolator. Security mechanism, hinge and alpha door design common to all port sizes
Beta
-
Optimal positioning of the lip seal
held in place by a securing ring which is either clipped (PE containers) or bolted to the flange (stainless steel containers) depending on the flange material.
-
Replaceable
locating lugs on the stainless steel and Aluminium flanges robust design made from low friction materials.
-
Wear indicators for stainless steel, aluminium and PE flanges.
The locating lugs on the stainless steel and aluminium flanges are replaceable making it easy for the user to restore the beta flange to ex-works condition at any time.
-
Easy to change lip seal
All our lip seals are made from silicone using high precision molding techniques.
-
Reduced docking torque and low friction silicone lip seals
from new design of locking ramps.
The : a state of the art for rapid transfer port
The innovative design of the security actuating mechanism ensures that no damage to the beta flange or door occurs during the connection. The interlock system acts directly on the main-shaft of the security interlocks to ensure a positive, precise and reliable action.
No fragile membranes are used for sealing the security mechanism. The use of o-ring seals only guarantees robustness and long term reliability of leak tightness.
The system includes new high performance for lip seals with lower torque and reduced zone of incertitude.
