Solvent purification

Solvent purification: on-site distillation vs. pre-purified canisters

Problem: A) Solvents of very high purity (e.g. moisture or oxygen free) are needed in organic chemistry research and they cannot be easily purchased or poured from open bottles. Dedicated stills occupy hood space and can be hazardous.
Solution: Purchasing purified canisters of solvents with purging and scrubbing dispensers.
Cost: The start-up costs can be more expensive than distillation and annual costs are about $1,000 per solvent greater as well. See our in-depth cost comparison.
Benefit: There may be some labor savings and safety improvements are invaluable. Gaining hood space is also precious. This eliminates need for cooling water which can amount to tens of thousands of liters every year.
