The IonKleen SL purifier has been specifically designed for the removal of metal ions from organic solvents and mixtures of organic solvents and resins. It is well-suited for use with raw materials used in the production of photoresists and for ultra high purity solvent applications. By utilizing ion exchange groups, which are covalently bonded directly to the surface of a traditional membrane filter, the IonKleen SL purifier provides spontaneous and immediate metal removal from various base solvents and resin solvent mixtures.
- 90% metal removal
- Simplifies purification techniques
- High capacity
- Shipped dry
- Manufactured in a cleanroom environment
The IonKleen SL purifier is recommended for solvent point-of-use purification and for use in purifying the precursor materials (solvents, resins and polymers) used in the manufacture of photoresists. It has also shown positive results in the purification of bulk and point-of-use IPA dispense.
