The Pure Solv Micro solvent purification system is designed as both an economic and space friendly alternative to the larger more traditional free standing units, only 12in. W x 13in. D x 19in. H. This purification system will remove water from approximately 100 L of solvent using the same proven design as the Innovative Technology, Inc. Pure Solv MD system. Pure Solv Micro is perfect for the researcher with modest requirements for a single anhydrous solvent who prefers the convenience of having a dedicated solvent drying and dispensing station. No longer do you have to share; now you can have your own.

We provide different vaccum equipments:

• Gauges and Manometers - (32)

• Manifolds - (55)
