Wilmad Universal Jet Tube Cleaner W/24/40 Joint For 2.5 mm

Universal Solvent Jet Washers for NMR and EPR Sample Tubes

The Universal Solvent Jet NMR Tube Washer can be used for any length NMR sample tube by a simple adjustment of the flexible PTFE tubing.By loosening and retightening the fitting on the assembled washer head, the PTFE tubing that extends into the sample tube is adjusted to the proper length. The washer head is then affixed to a filter flask (with vacuum sidearm) and the side tubing is inserted into a washing solvent reservoir. After an inverted sample tube is placed over the PTFE tubing, a vacuum is applied to the flask, sample tube is pressed against the rubber gasket to form an air-tight seal that starts the solvent flow.By lifting the PTFE tubing out of the solvent reservoir, the sample tube can be air-dried.
