Kontes Vacuum Flasks, Airless/Straus

Round bottom type developed by Kontes for solvent storage as required by many inorganic reactions. Dry, deoxygenated, and grease-free solvents are maintained in this state for relatively long periods of time. Solvent integrity is provided by the Kontes HI-VAC valve which provides access to the flask contents. Quantities of solvent are withdrawn from the flask using either a cannula or a syringe with a proper length needle.
