Rotary Evaporator – 20LT

The 20LT Rotary Evaporator by Wiggens is a powerful and reliable solution for industrial and laboratory applications across South Africa. Designed for the efficient separation of volatile components from higher boiling point substances, this rotary evaporator uses high-quality borosilicate glass and PTFE materials for enhanced chemical resistance and safe operation.

Its hydraulic heating bath ensures precise thermal control while preventing overheating. A 7″ intuitive touch-screen display enables real-time monitoring and adjustment of key parameters such as temperature and rotation speed. Explore our full range of rotary evaporators and related solutions at Apex Scientific and visit our Insights page to learn more about their features and applications.

The 20LT Rotary Evaporator is an indispensable tool for laboratories in South Africa, expertly designed for both industrial and laboratory applications. This advanced equipment efficiently evaporates volatile components while separating them from higher boiling substances, thanks to its robust construction using borosilicate glass and PTFE, which can handle aggressive substances.

 

Efficient Heating and Safety Features

This rotary evaporator features a hydraulic heating bath that can automatically lower during power failures, preventing overheating and bumping of fluids. Additionally, the transparent protection shield enhances safety during the evaporation process, allowing for easy monitoring.

 

Superior Sealing System

A standout feature of the ST20 is its self-lubricating sealing system, which ensures perfect vacuum tightness up to 5 mbar. This design minimizes maintenance needs and significantly reduces process time by allowing for low evaporation temperatures. The thermostatic bath accommodates both water and oil, reaching maximum temperatures of 150°C, making it versatile for various solvents.

 

Advanced Monitoring and Control

The Rotary Evaporator – 20LT comes equipped with a 7″ touch-screen display that allows for precise measurement and monitoring of critical parameters, including:

  • Bath temperature
  • Vapor temperature
  • Rotation speed
  • Vacuum levels

 

These features ensure that users can easily set and track the necessary operational parameters for their specific applications.please reword and improve this content. i will use it to support a video of this equipment on my website product page. Please make it 80 words. can you also give me marketable and attention-grabbing title?
