Karvil
Removes air bubbles and moisture while improving reaction quality and product density.
Integrated water mold temperature controller maintains stable heating for laboratory reactions.
SS304 mirror polished mixing chamber and sigma blades ensure easy cleaning and contamination-free processing.
The laboratory mixer uses the same Sigma mixing principle as industrial models, allowing users to optimize formulations before mass production.
Two counter-rotating Sigma blades continuously divide, stretch, compress and fold materials inside the mixing chamber. Under vacuum conditions, air and moisture are removed while temperature is accurately controlled through the jacket connected to the water mold temperature controller. The result is highly efficient mixing with excellent reaction consistency.
Solution:
Dual Sigma blades continuously fold, stretch and compress materials to achieve highly homogeneous mixing.
Solution:
Integrated vacuum system reaches -0.09 MPa to eliminate bubbles and improve reaction stability.
Solution:
Water mold temperature controller provides accurate heating between 35°C and 100°C (customized).
Solution:
Mirror-polished SS304 contact surfaces and manual tilting discharge make cleaning fast and convenient.
