Flash Columns
Flash columns from Hawach Scientific Co., Ltd. are prepacked chromatography cartridges designed for medium-pressure liquid chromatography in analytical and preparative applications. Each column contains silica gel or C18 stationary phase with particle sizes of 40-63μm and pore size of 60Å, housed in medical-grade polypropylene or glass. The columns are engineered for reproducible flow rates and consistent bed stability under standard lab conditions, supporting both normal-phase and reverse-phase separations without channeling or collapse.
The stationary phases include standard silica gel, spherical C18, NH2, C4, CN, HILIC, and functionalized variants such as SAX and SCX. These are packed under controlled conditions to ensure uniform density and minimal void volume. The frits are made from polyethylene, compatible with common organic solvents including methanol, acetonitrile, and dichloromethane. These columns are not sterilized and are intended for laboratory use only, not for clinical or pharmaceutical manufacturing under GMP.
Primary buyers include university research labs, pharmaceutical R&D departments, and chemical distributors sourcing fine compound purification tools. The columns are sold in bulk, typically in packs of 10 or 25 units, with no minimum order quantity enforced by the supplier. Packaging is in sealed plastic sleeves with barcode labels for traceability. Lead times for standard configurations are typically 7-14 days from Xi'an, with shipping via DHL or FedEx under FOB terms. Custom packing or labeling is available on request.

Sourcing Flash Columns from Hawach Scientific Co., Ltd. - China Import Guide
Before ordering flash columns from Hawach Scientific, verify the exact stationary phase type and particle size against your chromatographic method. Confirm the housing material matches your pressure and solvent requirements. Request a sample batch for system suitability testing if used in method development. Do not assume all phases are endcapped or certified for regulated use unless explicitly confirmed in writing.
Lead time for standard configurations is typically 7-14 days from Xi'an. Shipping is usually FOB, with freight arranged by the buyer. Incoterms are not listed; confirm whether DAP, CIF, or EXW applies. Payment terms are not stated, but T/T is common for Chinese suppliers. Always request a commercial invoice with HS code 3926.90 for customs clearance. No export documentation is mentioned, so confirm packing list and origin certificate are provided.
Inspect each column upon receipt for physical damage, frit integrity, and label accuracy. Check for leaks under low pressure before use. For silica-based columns, test retention time with a known standard like naphthalene or toluene to confirm phase performance. Retain batch numbers for traceability. No QC certificates are provided, so perform your own system suitability test before scaling up any purification process.
