Optima - Performance

  • Leak tightness performance equals competition.
  • 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 alpha flange.
  • All beta flanges have wear limit indicators

Advantages of Optima 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 the ring

    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 on locating lugs of all flanges.

    The locating lugs on the stainless steel and aluminium flanges are replaceable making it easy for the user to restore the beat flange to ex-works condition at any time.

  • Easy to change lip seal

  • Reduction of the ring

    of potential contamination with new lip seal design.

  • Reduced docking torque

    from new design of locking ramps

  • Reduced docking torque

    by the use of a low friction surface finish on the lip seals.
