General description

The glass frit in the side-arm permits filtration of excess reagents and solvent removal with complete recovery of the resin for the next reaction. The "Schlaker" tube (derived from "Schlenk" and peptide "shaker") is designed for running oxygen and moisture sensitive reactions on a solid-phase resin.

Made of heavy-wall glass, with glass stopcock and frit (porosity 25-50 mm) on side-arm, and a plain or a threaded 14/20 top joint. Compatible with Schlenk glassware. Compatible with the Aldrich All-in-One Glassware Kit.

Schlaker Tube Technique

1. Place resin in the tube
2. Evacuate and purge with N2 to remove oxygen via a rubber septum or a septum-inlet adapter in the top joint
3. Stir gently while heating in an oil bath for high temperatures, or place on a shaker for room temperature reactions
4. When the reaction is complete, apply positive N2 pressure through the septum in the top joint, and vacuum to the side-arm
5. Tilt the Schlaker tube on its side to allow solvent and excess reagents to flow out, leaving the resin behind
