Import 100pieces 13mm Sterile Mce Syringe Filters — Buy in Bulk from Supplier in Hong Kong

A-Fit Biosciences (HK) Ltd. supplies these 13mm sterile mixed cellulose ester (MCE) syringe filters in packs of 100 units, designed for sample preparation in analytical chemistry. Each filter has a 0.22-micrometre pore size to remove fine particulates before HPLC or FPLC injection, and the 13mm diameter fits standard Luer-lock syringes. The filters are individually packaged to maintain sterility throughout handling and storage.

MCE membranes are hydrophilic and offer broad chemical compatibility with aqueous solutions and many mild organic solvents, making them a standard choice in pharmaceutical quality control and environmental water testing. Typical MCE filters support a maximum operating temperature around 45 degrees Celsius and a burst pressure above 3 bar, though exact ratings should be confirmed with the supplier. The membrane is composed of cellulose acetate and cellulose nitrate, a combination that provides consistent flow rates and low protein binding compared to some alternative materials.

Laboratories in biotechnology, food safety, and clinical research use these filters to clarify samples prior to chromatographic analysis, reducing instrument downtime from particulate fouling. Buyers should verify the exact housing material (typically polypropylene) and whether the supplier holds ISO 13485 or equivalent quality certifications for medical-device-grade filtration products. A-Fit Biosciences (HK) Ltd. is based in Hong Kong, and importers should confirm lead times, freight options, and whether bulk pricing tiers apply before placing a large order.

A-Fit Biosciences (HK) Ltd. is registered at 15B, 15/F, Cheuk Nang Plaza, 250 Hennessy Road, Hong Kong. The supplier is listed as an imported-tier seller on the platform, and its trust tier is designated as harbour, indicating it has completed basic verification but has not yet achieved higher-tier status. The listing shows a response rate of 0.00 percent with an average response time of zero hours, meaning prospective buyers should not rely on prompt platform messaging and may need to contact the company directly to confirm stock and terms.

The company profile does not disclose years in operation, employee count, manufacturing capabilities, or client references. The product description references ISO and SGS certifications, but these claims are not independently verified in the listing data, so buyers should request copies of any relevant certificates before committing to an order. A-Fit Biosciences (HK) Ltd. appears to focus on laboratory consumables and filtration products, positioning itself as a sourcing intermediary based in Hong Kong.
