Sigma Aldrich Drying Tube Assy for Chemical Dryer ST/NS 34/35

The Sigma Aldrich Z222712 Drying Tube Assembly is a piece of laboratory glassware used to protect chemical reactions or reagents from moisture and other contaminants by placing a solid desiccant inside. Drying tubes are essential in synthetic organic chemistry, particularly when dealing with air-sensitive or water-sensitive reagents. The tube is charged with the desiccant and attached to the apparatus, allowing the small amount of air drawn into the system as it cools to be dried, preventing moisture from entering the reaction environment.

Used, in great condition.
