Import Asone Reusable Class A Wash Bottle 500ml — Buy in wholesale FOB from Supplier in China

The ASONE Reusable Class A Wash Bottle 500ml from Njbzhlab is a precision laboratory vessel designed for controlled dispensing of wash solvents, distilled water, and cleaning solutions in analytical and research settings. This 500 millilitre capacity bottle carries Class A volumetric certification, indicating compliance with strict international tolerance standards for quantitative work. Njbzhlab manufactures this unit from chemically resistant polymer materials suited to trace analytical applications, with a narrow delivery tube that permits directed, low-velocity liquid streams to minimise splashing on sensitive apparatus. The bottle is reusable rather than disposable, supporting cost reduction and waste minimisation in high-throughput facilities.

The body is formed from low-extractable fluoropolymer-based material, standard for PFA-grade laboratory containers where metal ion contamination below parts-per-billion levels is critical. Class A designation means the graduated markings meet or exceed typical DIN/ISO 1042 tolerance specifications, typically +/- 2.0 ml at 500 ml capacity for Class A borosilicate analogues, though polymer equivalents follow similar verification protocols. The screw closure integrates a one-piece delivery tube with protective cap to prevent dust ingress and cross-contamination between uses. Typical applications include final rinses of volumetric glassware, reagent addition in cleanroom environments, and solvent washing of chromatography columns where residue carryover would compromise results.

Buyers include university research departments, semiconductor fabrication facilities, pharmaceutical QC laboratories, and environmental testing agencies operating ICP-MS or similar trace-element instrumentation. The 500 ml size represents a standard working volume that balances portability against refill frequency during extended analytical sequences. Njbzhlab offers OEM customisation of bottle dimensions, cap colours for solvent identification coding, and private-label marking. Import buyers should confirm material certification documentation, lot traceability records, and compatibility data for specific organic solvents or concentrated acids intended for use with this vessel.

Njbzhlab operates from Room 301, Building 10, Simcere Pharmaceutical premises within Xuzhuang Software Park, Xuanwu District, Nanjing City, Jiangsu Province, China. The supplier's trust tier is classified as harbor, and the response rate stands at 0.00 percent with zero average response hours recorded on the platform, indicating that direct enquiry through alternative channels may yield faster communication. Njbzhlab specialises in PFA-based laboratory products including beakers, reagent bottles, mixing bars, forceps, funnels, volume flasks, crucibles, water tanks, reaction bottles, washing bottles, and measuring bottles.

The supplier's source description states approximately 30 years of involvement in laboratory container manufacturing, with in-house design and production capabilities. Njbzhlab cites clientele including CUG (China University of Geosciences), IGCAS (Institute of Geochemistry, Chinese Academy of Sciences), and SGS, though buyers should independently verify current certification status and recent reference projects. The company promotes OEM services and emphasises product suitability for semiconductor, electronics, pharmaceutical, and chemical industries. No verified ISO certification, specific production capacity figures, or audited financial data is available from the listing; buyers should request these directly during due diligence.
