Custom Purified Solvents

If the basic specification is not what you're looking for then let us work with you to produce a profile of your solvent, based on your processing requirements. A unique specification is drawn up for you, so you get a consistent, controlled grade of solvent time after time. Just give us the following information:

Solvent specification Certification (certifcate of analysis or conformity) Packaging required (size and material) Brief details of application

Using a ROMIL-PUROM™ solvent, that is ‘fit for your purpose’, could well improve the yield and quality of your final product. And because you pay only for the performance you need you’ll save money at the same time.
