High purity Flow Tubes are available in a range of materials and lengths, so you can customize the tubes to your exact analysis requirements. Stainless steel Flow Tubes are intended as single use items, to avoid any carry-over from different sample matrices. Graphite Flow Tubes are designed to be cleaned wet chemically using mineral acids.

• Flow tubes, stainless steel, 20mm length; for general purpose usage, intended for single use to avoid memory effects (50 pieces)
• Flow tubes, stainless steel, 18mm length; for depth profiling, designed for single use (50 pieces)
• Flow tubes, graphite uncoated, 20mm length; for general purpose extra low detection limits. Can be acid cleaned with every mineral acid, including HF (singles)
