从Hong Kong供应商批量进口100pieces 13mm Sterile Nylon Syringe Filters

These 13mm sterile nylon syringe filters from A-Fit Biosciences (HK) Ltd. are supplied in boxes of 100 pieces and are intended for laboratory sample clarification ahead of chromatographic analysis. Each unit features a 0.22-micrometre nylon membrane housed in a compact 13mm body that connects to standard Luer-tip syringes. The filters are sterilised and individually sealed to reduce the risk of cross-contamination during sample preparation.

Nylon (polyamide) membranes are naturally hydrophilic and offer strong resistance to a broad spectrum of organic solvents, including alcohols, esters, and many hydrocarbons. This makes nylon filters a common selection in pharmaceutical formulation labs and environmental testing facilities where mixed aqueous-organic sample matrices are routine. Typical nylon membranes withstand temperatures up to approximately 100 degrees Celsius and maintain structural integrity under pressures commonly encountered in manual syringe filtration, though exact ratings vary by manufacturer.

Buyers in biotechnology, clinical diagnostics, and food-and-beverage quality assurance use nylon syringe filters to protect HPLC columns and ensure reproducible chromatographic baselines. The listing does not specify the housing material or exact pressure rating, so importers should request a technical data sheet from A-Fit Biosciences (HK) Ltd. before finalising a purchase. Confirm whether the supplier can provide lot-specific certificates of analysis and whether bulk-order pricing or staggered delivery schedules are available.

A-Fit Biosciences (HK) Ltd. operates from 15B, 15/F, Cheuk Nang Plaza, 250 Hennessy Road, Hong Kong. The supplier is classified as an imported-tier seller with a harbour trust tier, meaning it has passed foundational platform checks but does not hold an elevated verification badge. Its platform response rate is recorded at 0.00 percent with zero average response hours, so buyers should reach out through direct contact channels rather than relying on marketplace messaging for timely replies.

No information is provided about the company's founding year, workforce size, manufacturing partnerships, or distribution network. The product listing claims ISO and SGS certifications for the filters, but these assertions are not substantiated with certificate numbers or issuing-body details within the listing. Buyers are advised to request verifiable documentation and, if possible, arrange a third-party inspection or sample evaluation before placing a significant order with A-Fit Biosciences (HK) Ltd.
