Import Desheng Product Tris — Buy in wholesale FOB from Supplier in China

Desheng Product Tris, also known as tromethamine or tris(hydroxymethyl)aminomethane, is a biochemical buffer with CAS number 77-86-1 and a molecular weight of 121.135 g/mol. It appears as a white crystalline powder with a melting point between 168 and 172 degrees Celsius. The compound is supplied with a pH range of 7 to 9 and is stable under room temperature conditions when stored in a light-proof, moisture-proof environment. This product is produced using HPLC-purified methods to ensure purity exceeding 99%, consistent with industry standards for diagnostic reagents.

Tris functions as a zwitterionic buffer with a pKa of 8.1 at 25°C, making it effective in the pH range of 7.0 to 9.2, which aligns with standard requirements for molecular biology and in vitro diagnostics. It is commonly used in nucleic acid extraction, PCR buffer systems, and electrophoresis applications. The supplier does not list certifications such as ISO or GMP, but their internal HPLC purity validation suggests suitability for sensitive laboratory use. The product is not formulated with stabilizers or preservatives, and users must prepare aqueous solutions using high-purity water, typically double-steamed, to avoid contamination.

This Tris buffer is purchased by diagnostic reagent manufacturers, research labs, and biotech firms in Asia, Europe, and North America for use in assay development and quality control workflows. Buyers typically order in bulk quantities of 1 kg or more, with packaging in sealed polyethylene-lined drums or aluminum foil bags. Lead time and Incoterms are not specified in the listing; buyers must confirm these directly with the supplier. The product is not classified as hazardous under GHS, but handling requires standard laboratory precautions due to its alkaline nature when dissolved.

Desheng Technology is a manufacturer based in Ezhou, Hubei Province, China, specializing in biochemical reagents for in vitro diagnostics. The company develops and produces Good's buffers including Tris, HEPES, MOPS, and TAPS, alongside chromogenic substrates and luminescent agents. Their profile indicates a vertically integrated operation with in-house R&D and production, but no details are provided regarding company size, workforce, export history, or third-party certifications. The supplier's response rate and average response time are listed as zero, suggesting limited or no active customer service engagement.

There is no verified information on export volumes, client names, or quality management systems such as ISO 13485 or CE marking. The listing confirms HPLC purification for all products and claims purity above 99%, but does not provide test reports or batch-specific certificates. Buyers should treat this as a direct manufacturer with technical capability but unverified compliance infrastructure. The physical address provided is consistent with industrial zones in Hubei, but no warehouse or logistics details are disclosed.
