Filter Membranes

Hawach Scientific Co., Ltd. produces two main types of filter membranes: round disc membrane filters and roll type membrane filters. Both formats are designed for filtration and sterilisation of liquids, gases and other sample streams. The membranes remove microorganisms and particulate matter without altering the composition of the processed material. The company offers a broad range of pore sizes and material constructions.

Available membrane materials include PTFE, PVDF, Nylon, MCE, cellulose acetate, PES, glass fibre and polypropylene, covering most chemical compatibility requirements. In the filtration industry typical pore size selections run from 0.1 µm to 5 µm, allowing removal of bacteria and fine particulates. Standard operating temperature for PTFE and PVDF membranes is up to 120 °C, while most polymeric variants tolerate a pH range of 0 to 14. Typical pressure ratings are up to 2 bar for low‑pressure applications.

Common applications are water treatment, pharmaceutical processing, food and beverage production and laboratory sample preparation, where manufacturers and testing labs frequently source these membranes. Hawach offers OEM services and custom dimensions, so buyers should confirm minimum order quantities, lead times and preferred Incoterms directly with the supplier. Trade terms such as payment method and inspection requirements are negotiated per order.

Hawach Scientific Co., Ltd. is based in Xi'an, Shaanxi Province, China, with the address Room 1519‑1521, Building A1, No.32 Jinye Road, postal code 710077. The supplier is listed with a harbour trust tier, indicating a verified business profile within the marketplace. Current response statistics show a response rate of 0 % and no recorded average response time, which suggests limited communication activity. The company’s product catalogue focuses on filtration media for diverse industrial uses.

The listing states that Hawach provides both disc and roll membrane formats and can supply a wide selection of polymeric and inorganic materials. OEM services and custom size manufacturing are explicitly mentioned, allowing buyers to request dimensions beyond the standard offerings. No additional certifications, production capacity or years of operation are disclosed in the profile. Prospective importers should therefore obtain confirmation of any quality certifications and production capabilities directly from the supplier.
