LA Range: LAPP

Bigneat manufactures and installs LAPP enclosures for sample/process protection.

Bigneat’s LAPP enclosure has been designed following years of practical experience and is an example of Bigneat’s innovation in design & technology.
LAPP enclosures provide downflow sterile ISO Class 5 Clean air to the work surface ensuring protection of the sample/process.

Access to the enclosure interior during operation can be gained through the three lower sliding windows within the lower hinged door (access 11.8″ high) and full height sliding doors allowing for access to the robotics system inside the enclosure during use, loading and maintenance.

Interlocking upper and lower main access doors are locked down with ‘T’ handles during operation.

This enclosure’s air flow is 100% pass through system, air in and air out. Product protection is a paramount function for the LAPP model with automatic fan speed control maintaining a minimum face velocity when one door is open which complies to recognised Standards worldwide.


  • Great ergonomics with access to four sides of the robotic platform.
  • Excellent all-round visibility of the enclosed system.
  • Easy touch, state-of-the-art control system – displays enclosure status and controls airflow system, hour counter.
  • Display shows status of enclosed robotic system which is mounted to enclosure exterior.
  • Audible and visual alarm indication of low airflow.
  • Door open warning alarm.
  • Display/lighting beacons show status of enclosed robotic system.


Options and extras

  • Additional electrical sockets to suit robotics system.
  • Computer shelf on flexible arm.
  • Hydrogen peroxide or alternative fumigation connections, night doors, removed for normal operation.
  • Under-bench storage and shelving to suit.
  • Universal control panel.
  • UV lighting, linked to timed on/off facility in control system.
  • Variety of door options.
  • Waste tips and plates chute and ventilated waste container.
