NMR Tube Washers

Wilmad Labglass 2nd generation Multi-Tube Jet Solvent Washer/Dryer is recommended for research labs that routinely clean NMR and EPR tubes; a single unit can accommodate up to 5 tubes at once. When an inverted tube is inserted onto the solvent transfer tubing and the open end is immersed under wash solvent in the solvent cup, a reliable vacuum-tight seal will be formed and generate solvent flow under vacuum. After solvent is fully consumed, air flow will follow to turn the unit into a dryer. A filter flask with vacuum sidearm is required and can be purchased separately, see page 50.

Features:

• 5 PTFE coated stainless steel solvent transfer tubes fit 3, 4, and 5mm NMR/EPR tubes
• PTFE solvent cup and tubing make this unit resistant to common organic solvents
• Flanged reservoir connection eliminates joint freeze
• Grease-less joint between the solvent cup and glass reservoir eliminates possibility of contamination
• Complete disassembly without tools for easy cleaning
• Hands free during washing/drying cycle
• Calibrated length mark for 4, 7, 8 and 9” tube

Multi-Tube Jet Solvent NMR/EPR Tube Washer/Dryer

After fitting the washer to a filter flask, an inverted sample tube is inserted into the washer and solvent is introduced into the reservoir using a series of wash bottles. You can perform numerous wash steps and finish by pulling vacuum to dry the tube.

Wilmad Labglass Universal Solvent Jet Washer can be used for any length sample tube by a simple adjustment of the flexible PTFE tubing. It is especially recommended for cleaning gas-tight sample tubes.

By loosening and re-tightening the tubing 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 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 and the 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.
