Stainless steel spring shaped packing is made of thin metal wire into a spiral shaped spring coil, which disperses the liquid into an extremely thin liquid film through the capillary action of the metal wire. The diameter of the spiral coil is about 2.4mm, and it is used in laboratory distillation columns with a plate height ranging from 25 to 58mm. Similar types of spiral shaped packing include triangular, square, and polygonal ones. Generally made of metal wire or glass wire, it belongs to the category of high-efficiency fillers.

Stainless steel spring packing is also a type of Fenske packing, which is made of thin metal wire into a spiral spring coil. The liquid is dispersed into an extremely thin liquid film by the capillary action of the metal wire. The diameter specifications of the spiral coil range from Φ 1.5 to Φ 12 and are commonly used in laboratory distillation columns. It is also one of the high-efficiency packing materials commonly used in laboratories and is mainly used for high-purity distillation experiments in laboratories.
