CHEMGLASS CG-1854-01 NMR TUBE CLEANER 5-POSITION

All glass and PTFE design cleans five NMR tubes of the same, or various, lengths and diameters. PTFE adapter has five positions with flexible 1/8” PTFE tubing supplied in 9” lengths that can be cut to desired height. The NMR tube is placed over the tubing and seats in the adapter, leaving a small space between the end of the PTFE tubing and the inside bottom of the NMR tube. With the stopcock in the closed position, the reservoir is connected to a low vacuum source. Cleaning solvent is added into the adapter followed by air drying to complete the process in seconds.
