This 1000ml volumetric flask from Nanjing Binzhenghong Instrument Co, Ltd. is manufactured from virgin PFA (perfluoroalkoxy) resin, a fluoropolymer known for its exceptional chemical inertness and thermal stability. It meets Class A tolerance standards per DIN EN ISO 1042, ensuring precise volume measurement for analytical work. The flask features a screw cap design rather than a traditional ground-glass stopper, which reduces the risk of sample contamination from external sources.
PFA offers distinct advantages over borosilicate glass, PTFE, and polypropylene in trace analysis. Its non-porous, low-adhesion surface minimizes sample carryover between uses, a critical factor when working at parts-per-billion or parts-per-trillion detection levels. The material withstands repeated sterilization cycles via autoclaving (heat), ethylene oxide (gas), or chemical disinfectants without degrading, making it suitable for both inorganic trace metal work and sensitive biological sample preparation.
Laboratories conducting ultra-trace environmental analysis, semiconductor chemical purity testing, and pharmaceutical quality control are typical buyers of PFA volumetric flasks. The 1000ml capacity is commonly used for preparing standard solutions and diluting high-purity reagents. Buyers should confirm the exact MOQ, unit pricing, and lead time directly with Nanjing Binzhenghong, as these trade terms are not specified in the listing and may vary depending on order volume and destination.

Before placing an order for PFA volumetric flasks from this Nanjing-based supplier, confirm the exact unit price, volume-based discounts, and minimum order quantity. The listing does not specify these trade terms, and they are essential for budgeting, especially if you are ordering for a multi-user laboratory or reselling. Also ask whether the supplier can provide a proforma invoice with HS code and declared value for customs clearance in your country.
Shipping PFA labware from China typically involves air freight for smaller orders or sea freight for bulk shipments. PFA flasks are relatively lightweight but require careful packaging to prevent cracking or scratching of the graduated markings. Request that the supplier use individual carton inserts or foam padding, and confirm the estimated lead time from order confirmation to dispatch. Clarify whether the quoted price includes export packaging or if it is charged separately.
Quality verification on receipt should include a visual inspection for clarity, absence of bubbles or inclusions in the PFA body, and legibility of the graduation marks. If your application demands verified Class A accuracy, consider requesting a batch calibration certificate or performing a gravimetric check with deionised water at 20°C. For trace-metal work, a blank acid leach test on a sample flask from the batch can confirm that the PFA does not contribute measurable contamination.
