Description General description This Wilmad 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 (3, 4 and 5 mm OD) 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. Features: • 5 PTFE coated stainless steel solvent transfer tubes fit 3, 4 and 5 mm NMR/EPR tubes • PTFE solvent cup and tubing make this unit fully resistant to common organic solvents • Flanged reservoir connection eliminates joint freeze • Greaseless 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 in., 7 in., 8 in. and 9 in. tube
