The Rotary Evaporator Explosion Proof – 20LT by Wiggens is a cutting-edge solution for laboratories in South Africa, specifically designed for both industrial and laboratory applications. This large-capacity rotary evaporator effectively meets all process requirements while utilizing robust borosilicate glass and PTFE, enabling safe handling of aggressive substances.

 

Efficient Operation Under Various Conditions

This rotary evaporator operates seamlessly under both vacuum and atmospheric conditions. The rotation of the 50 or 100L evaporation flask within its thermostatic bath promotes forced convection, ensuring uniform distribution and preventing sedimentation. With a high evaporating exchange surface, this unit facilitates optimal evaporation rates, making it essential for various laboratory processes.

 

Safety Features for Enhanced User Protection

Safety is paramount in laboratory operations, and the Rotary Evaporator Explosion Proof – 20LT excels in this regard. It incorporates a transparent protective shield over the thermostatic bath, providing maximum safety against glass breakage and high-temperature sprays. The hydraulic system automatically lowers the bath during power failures, door openings, or overheating, ensuring that operations can be managed safely.

 

Maintenance-Free Vacuum Sealing System

One of the standout attributes of this rotary evaporator is its self-lubricating sealing system, which guarantees perfect vacuum tightness without the need for maintenance. This feature not only simplifies operation but also reduces downtime, allowing for continuous workflow.

 

Advanced Monitoring and Control

The Rotary Evaporator Explosion Proof – 20LT includes a sophisticated electronic controller that allows users to manage parameters easily. The graphical color display, featuring a 7″ touch-screen, provides real-time monitoring of key operational conditions. Users can save and recall up to 20 customizable methods, enhancing flexibility in various applications.

 

Versatile Applications Across Industries

This rotary evaporator is widely utilized in industries such as pharmaceuticals, chemicals, cosmetics, herb extraction, petrochemicals, and food processing. It is suitable for a broad range of applications, including:

  • Continuous and discontinuous distillation
  • Solvent recycling
  • Reflux reactions
  • Component drying
