Import Bangkai Column Chromatography Silica Gel 60 — Buy in wholesale FOB from Supplier in China

Bangkai Column Chromatography Silica Gel 60 is a synthetic amorphous silicon dioxide adsorbent produced by Qingdao Bangkai Hi-Tech Materials Co., Ltd. in Shandong, China, with CAS number 7631-86-9 and chemical formula SiO2. The supplier specifies 99% purity, white powder appearance, and a 60 Angstrom pore diameter, placing it within the standard pore size classification for routine chromatographic separations. The specific surface area is reported at 450-600 m2/g, with pore volume of 0.5-0.7 ml/g, values consistent with high-surface-area silica gel manufactured by controlled precipitation and ageing processes.

The product functions as an adsorbent in column chromatography for preparative and analytical scale separations of organic compounds, with the 60 Angstrom pore size suited to molecules below approximately 4000 Daltons. Industrial silica gel of this type is typically produced by acidifying sodium silicate solution to form a hydrogel, followed by washing, drying, and controlled milling to achieve the desired particle size range for column packing. The pH is listed as negotiable, indicating the supplier may adjust surface acidity or offer neutralised variants for acid-sensitive compound purification.

Primary users include pharmaceutical manufacturers performing API intermediate purification, natural product isolation laboratories, and chemical synthesis groups requiring scalable flash or gravity column chromatography. The powder form requires careful slurry packing or dry loading techniques depending on column diameter and solvent system. Importers should discuss whether the supplier offers narrow particle size fractions (e.g., 40-63 micrometres for flash chromatography, 63-200 micrometres for gravity columns) and whether the material requires activation before use.

Qingdao Bangkai Hi-Tech Materials Co., Ltd. is headquartered at No.2 Jinsheng 2nd Road, Jihongtan, Qingdao, Shandong Province, 266000, China, operating as a chemical auxiliary agent and adsorbent manufacturer under the Bangkai brand. The company holds a Harbor trust tier on its marketplace profile, with recorded response metrics showing 0.00% response rate and zero average response hours. This profile pattern indicates minimal platform-mediated communication, so prospective buyers should seek direct contact through the supplier's official channels to evaluate technical enquiry handling and sales support responsiveness.

The supplier's disclosed product range spans coating auxiliary agents, petroleum additives, surfactants, and chromatography materials, with silica gel powder positioned across industrial and laboratory grades. No information is available on manufacturing scale, number of production lines, quality control laboratory accreditation, or key account relationships. The source description references ISO standards in general terms without certificate numbers or certifying body names. Buyers should request current quality system certificates, manufacturing process descriptions (sol-gel versus precipitation), and evidence of batch release testing protocols before reliance on the material for critical separations.
