What are the key operating precautions for laboratory vacuum emulsifiers?
2025-11-07
Safe and effective operation requires following these guidelines:
Pre-Operation Check: Ensure the vacuum system is leak-free, the homogenizer rotor is securely installed, and all safety guards are in place. Clean the mixing chamber thoroughly to avoid cross-contamination between batches.
Material Preparation: Cut solid materials into small pieces (to speed up dissolution) and pre-mix low-viscosity liquids (to reduce homogenization time). Avoid adding excessive solid particles directly, as this may damage the shear rotor.
Vacuum Application: Gradually increase the vacuum level (avoid sudden high vacuum) to prevent material splashing. Monitor the vacuum gauge during operation—if pressure rises unexpectedly, stop and check for leaks.
Speed Control: Start the homogenizer at a low speed, then gradually increase to the target speed (high-speed operation should not exceed the recommended duration to prevent overheating of the motor).
Post-Operation: Turn off the homogenizer first, then release the vacuum slowly. Clean the equipment immediately after use (use neutral detergents; avoid abrasive cleaners that scratch the chamber surface).
