The product is a gravity chromatography empty column, using high-purity ultra-high molecular weight polyethylene (UHWMPE) as raw material processed by special process, with not suitable for bubbles and hydrophilicity, and this material has been proved by many applications to have the advantages of clean and non-toxic, not combined with biomolecules and low solubility. The cylinder height is 66 mm, the inner diameter of the cylinder is 12.7 mm, and the total filling volume is 6 mL. The sieve plate is placed at the upper and lower ends of the packing matrix during filling and can be used for most chromatography packing filling.

Different specifications of gravity chromatography columns are shown in the figure below：
