Import 25ml Pfa Volumetric Flask For Analysis — Buy in wholesale FOB from Supplier in Mexico

PFA (perfluoroalkoxy) volumetric flasks are precision-calibrated containers manufactured from soluble polytetrafluoroethylene, a fully fluorinated polymer that provides exceptional chemical inertness for trace-level analytical work. This 25ml capacity unit features a transparent, pear-shaped body with a narrow neck to facilitate accurate meniscus reading and controlled liquid agitation, with scale lines calibrated using an electronic balance to one-thousandth precision. The flask accepts either threaded or plug-in cap configurations, and the complete size range spans 10ml through 1000ml for method scalability across protocols.

The PFA material delivers operating temperature stability from -200°C to +260°C, rendering it suitable for cryogenic sample preparation through to heated digestion procedures. Its non-stick, low-adhesion surface prevents sample retention on inner walls or at the bottle mouth, eliminating cross-contamination between sequential analyses. Metal element background is suppressed to below 0.01PPb for lead and uranium, achieving detection limits compatible with ICP-MS ultra-trace work; this low-leach characteristic is standard for fluoropolymer labware intended for semiconductor and environmental monitoring applications.

Target buyers include analytical laboratories running isotope analysis, environmental testing facilities, semiconductor fabrication plants, polysilicon producers, photovoltaic cell manufacturers, and lithium battery research groups. Typical procurement involves confirming cap style (threaded versus plug-in), verifying calibration certificate availability, and establishing whether lot-specific trace metal analysis data is provided. The supplier's listed address places operations in Nanjing with Mexico declared as origin country; buyers should clarify actual manufacturing location and any associated customs documentation before placing orders.

Nanjing Bin Zhenghong Instrument Co., Ltd holds a Harbor trust tier on the source platform, with a listed address in Nanjing, 210018. The supplier's origin country is declared as Mexico, though the operational headquarters and postal code correspond to Nanjing, China; this discrepancy in geographic attribution is a point buyers should clarify directly with the company before proceeding. The response rate stands at 0.00% with zero average response hours recorded, indicating no historical engagement data is available through the platform's tracking systems.

The supplier's profile does not state year of establishment, employee count, revenue figures, factory certification status, or named client references. No ISO, GMP, or laboratory accreditation credentials are mentioned in the available data. Buyers are advised to request a supplier capability questionnaire, recent audit reports, and sample calibration certificates during initial qualification. The product description emphasises ICP-MS-grade low background as a key differentiator, suggesting the supplier targets high-purity analytical markets, though independent verification of trace metal test data should be obtained.
