Shimadzu, 208-90038-13, Tubing for Pumping Sample 1.65 mm ID (Pack of 12)

Shimadzu sample pump tubing is the replaceable sample-delivery line for compatible hydride vapor generation accessories in atomic absorption spectroscopy. The 1.65 mm internal diameter is larger than the corresponding reagent-pump tube and must be matched to the correct pump channel. The tubing provides a controlled path for transferring prepared samples into the reaction circuit, where consistent flow helps maintain repeatable vapor generation and analytical response. Wear, compression changes or blockage can alter delivery even when the instrument remains operational, so periodic inspection is important. During servicing, label all fluid lines, route the replacement tube through the specified roller positions and check connections for leaks. Prime the sample path and verify stable signal with suitable standards after maintenance. The twelve-piece pack is intended for repeated replacement of a consumable line; it does not include the pump mechanism, reaction manifold or vapor generator.
