Luer to fused silica capillary adapters are useful for quick and easy column rinsing/flushing or filling for storage. Conical bore fused quartz in polymer Luer-lok fitting accepts capillary in three size ranges: 0.090mm to 0.200mm OD (micro CE), 0.150mm to 0.375mm OD (CE and micro GC) and 0.300mm to 0.750mm (GC). Every well equipped laboratory should have a few handy for tackling unforeseen problems like contaminated columns. Best practice wet storage for CE columns is easily facilitated when combined with IQ column end caps. Reusable if columns cut with reasonable care.
