Import 250ml Pfa Gas Wash Bottles — Buy in wholesale FOB from Supplier in China

Nanjing Binzhenghong Instrument Co, Ltd. supplies PFA gas wash bottles in a 250ml capacity, part of a range that also covers 100ml, 500ml and 1000ml sizes. These vessels are constructed from perfluoroalkoxy (PFA) fluoropolymer, a material selected for its broad chemical inertness and thermal stability. The 250ml unit features a porosity dispersion disk and an FEP stopper with dedicated inlet and outlet ports for controlled gas flow. Temperature resistance spans from -200°C to +260°C, allowing use across cryogenic through high-temperature protocols. The translucent body permits visual monitoring of liquid level and bubble formation during operation. MOQ is stated as one piece, with some items held in stock for prompt dispatch.

PFA was chosen over borosilicate glass or PTFE for applications where metal leachables must be eliminated and long-term chemical storage stability is required. The material is non-stick and therefore straightforward to clean between runs, a critical factor in trace analysis where carryover must be minimised. Break resistance exceeds that of conventional glass gas wash bottles, reducing replacement frequency in busy laboratories. The FEP stopper maintains seal integrity while resisting attack from concentrated acids, bases and organic solvents that would degrade standard elastomeric closures. In standard laboratory practice, these bottles are filled with water for humidification, concentrated sulphuric acid for drying, or selective absorbents for targeted contaminant removal.

Typical purchasers include environmental testing laboratories, semiconductor fabrication facilities, pharmaceutical QC departments and academic research groups running ICP-MS, GC or other gas-dependent analytical techniques. The 250ml size suits bench-scale work and method development before scale-up to larger vessels. Buyers should confirm with Nanjing Binzhenghong Instrument Co, Ltd. whether the specific absorbent or scrubbing liquid they intend to use is compatible with the FEP stopper material over extended contact periods. Incoterms, lead times and exact stock levels for the 250ml variant should be verified directly with the supplier, as these are not specified in the listing materials.

Nanjing Binzhenghong Instrument Co, Ltd. is located at 301, Building 10, Baijiahui Chuangxin Community, No. 699-18, Xuanwu Avenue, Xuanwu District, Nanjing City, Jiangsu Province, with postal code 210000. The supplier holds a harbour trust tier on the platform, which represents a baseline verification level. The response rate is recorded at 0.00% with an average response time of zero hours, indicating that no enquiry response data is currently available through the platform interface. Buyers should therefore anticipate that direct follow-up via email or telephone may be necessary to establish communication.

The company lists laboratory plasticware and fluoropolymer analytical equipment, with this particular product line focusing on PFA gas wash bottles for gas purification and conditioning applications. No information is provided about year of establishment, factory floor area, employee count, annual revenue, export licence status, ISO certifications, or named client references. The listing does mention that some items are held in stock and can be dispatched promptly, though it does not specify which sizes or quantities. Prospective buyers are advised to request a current stock list and to verify quality control documentation for the specific batch they intend to purchase.
