Shimadzu, 038-00155-03, Sample cup. 20 mL, 0113-03

The Shimadzu 20 mL sample cup is a laboratory consumable for holding liquid specimens used in compatible atomic absorption autosampler workflows. The cup measures approximately 28 mm in diameter and 48.5 mm in height, providing a defined geometry for supported rack positions and sample aspiration procedures. It can be used in suitable Shimadzu sample introduction systems, including furnace and flame micro-sampling arrangements where the specified cup holder is fitted. The open vessel is intended to contain prepared standards, blanks or digested analytical samples for aspiration; it is not a storage vial with a sealed cap or a volumetric measuring flask. Correct placement and liquid height help achieve reliable uptake without the autosampler probe touching the vessel base. Sample solutions must be chemically compatible with the cup material and the instrument's handling procedure. Use clean cups to reduce carryover and matrix contamination between samples. Confirm rack and method compatibility before using replacement cups.
