CT15R-MF

The CT15R-MF is a 15 mL metal-free centrifuge tube engineered for workflows where trace metal contamination from standard labware would compromise results. Manufactured from high-purity polypropylene using non-metallic tooling, more than 21 elemental impurities are controlled to below 1 ppb, verified by ICP-MS — making it the required format for trace metal analysis, ICP-OES/ICP-MS sample preparation, and any assay sensitive to metal ion interference at sub-ppb levels.

◆ >21 elemental impurities <1 ppb — ICP-MS verified; Certificate of Analysis available for each lot

◆ Non-metallic mold tooling — eliminates mold-surface metal leaching that can affect standard PP tubes without compromising dimensional accuracy or wall uniformity

◆ 15,000×g centrifuge rating — conical bottom ensures complete pellet recovery; identical performance spec to standard CT15 line

◆ Rack pack format — 25 pcs/rack, pre-organized for sequential sample processing; reusable autoclavable PP racks compatible with interlocking workstation setups

◆ Storage to −80°C — suitable for long-term cryogenic storage of trace-element-sensitive samples

◆ DNase/RNase-free, endotoxin-free, sterile — shelf life 5 years

Ideal for: ICP-MS/ICP-OES sample preparation, trace metal analysis, environmental monitoring, food safety testing, drug development, clinical diagnostics requiring ultra-low metal background
