Dixon Ring Tower Packing

Dixon Ring Tower Packing from Jiaxing Xudong Industry Equipment Co., Ltd is a structured mesh packing designed for laboratory-scale distillation and mass transfer applications. The rings are formed from fine stainless steel mesh with an outer diameter of 6 mm and a height of 3 mm, matching standard laboratory column dimensions. These dimensions allow for uniform packing density and predictable void fractions in small-diameter columns, typically under 50 mm internal diameter. The material is non-reactive and suitable for use with organic solvents, acids, and aqueous systems commonly found in analytical chemistry setups.

The performance of these rings relies on surface tension effects: when wetted, the mesh expands its effective surface area, enhancing vapor-liquid contact. This behavior is typical of high-efficiency mesh packings in lab distillation, where surface-to-volume ratio is critical. Unlike random packing such as Raschig rings, Dixon rings require pre-wetting to achieve optimal mass transfer rates, a procedural step documented in laboratory manuals for fractional distillation. The supplier provides rings in bulk quantities, typically sold by weight or by volume for column filling, with no minimum order specified in the listing.

These packings are primarily purchased by research laboratories, university chemistry departments, and small-scale pharmaceutical development units conducting batch distillation or solvent recovery. Buyers often require consistent ring geometry and material purity to ensure reproducible results. Trade terms are typically FOB Shanghai, with packaging in sealed plastic bags inside cardboard boxes. Lead time is not confirmed in the listing; buyers should request it directly from the supplier. Packaging may vary based on order volume and shipping method.

Jiaxing Xudong Industry Equipment Co., Ltd is a manufacturer based in Baibu Town, Jiaxing, Zhejiang, China, focused on laboratory and pilot-scale process equipment. The company's profile indicates experience in producing glassware, distillation components, and structured packings for research use. No information is provided regarding company size, years in operation, or export history. The supplier's trust tier is listed as harbor, indicating basic platform verification but no third-party certification or audit records visible in the listing.

The supplier does not claim certifications such as ISO or CE, nor does it list client names or production capacity. Their listing emphasizes technical accuracy of laboratory packings rather than commercial scale. Buyers should confirm material grade, dimensional tolerances, and batch consistency directly with the supplier before placing orders. The company has no public website or contact details beyond the platform profile, and response rates are currently unrecorded.
