CT50B-MF 50 mL Metal-Free Centrifuge Tube (CAT#: STEM-AL-3089-ZJF)

CT50B-MF is a metal-free polypropylene centrifuge tube for laboratory sample processing and storage. The vessel is configured for centrifugation of liquid samples and suspended material. Its trace-metal-controlled construction reduces background contamination in elemental analysis workflows. The tapered base directs sediment toward the bottom for pellet recovery. The clear tube body supports visual inspection of sample level and separation progress. A fitted cap provides contained handling during processing and storage. Graduations and a writing area support volume reading and sample identification. Bulk packaging supports laboratories with frequent tube consumption. The tube is intended for contamination-sensitive analytical preparation.
