| A new application of the
WALL WETTER |
WW
CRYSTAL PLUS |
| BEST FOR A BATCH
CRYSTALLIZATION WITH FINE TRAP. |
|
¡STRUCTURE
WW crystal plus system consists of a WALL
WETTER and a vessel with two separated jackets
and each jacket would be controlled at different
temperature levels. In case the
upper jacket will be heated it shall work
as a fine trap.

|
¡EXAMPLE
|
Change of concentration
|
 |
Comparison of average crystal sizes
|
 |
¡FEATURES
- The average crystal size becomes larger than by the conventional
method.
- Decreasing fine crystals. ¨ easy filtration
- After concentration the crystallization starts soon.
- It becomes shorter than the conventional system.
- A distribution of crystal size becomes narrow.
- Easy cleaning in a vessel.
- Less contamination. GMP applicable.

¡Polymorphs control
By controlling the temperature of the upper
jacket and the lower jacket the temperature
of the slurry could be controlled accurately.It
might make possible to get polymorphs.
