Stainless steel resin column

Stainless steel resin column is a commonly used equipment in laboratory and industry, mainly used in the process of substance separation, purification and preparation.

• Column: The column of stainless steel resin is usually made of stainless steel, which has the characteristics of being strong and durable, strong resistance to pressure, etc., can withstand certain pressure and temperature changes, suitable for various industrial environments. Stainless steel material also meets GMP (good manufacturing practice) requirements, ensuring the hygiene and safety of equipment.
• Resin bed: The resin bed is the core part of the adsorption column, which is filled with macroporous resin or other types of resin. The resin has good adsorption properties and can selectively adsorb specific components in the mixture to achieve separation and purification of substances.
• Inlet and outlet: The inlet and outlet are located at the upper and lower ends of the column, respectively, for feeding and discharging. The inlet introduces the solution to be treated into the adsorption column so that it can fully contact with the resin bed; the outlet discharges the solution after adsorption treatment.
• Filter device: the column usually has a filter device inside, such as stainless steel filter screen or stainless steel water cap, which is used to prevent resin particles from entering the solution and ensure the purity of the discharge liquid.

1. Adsorption: The solution to be treated enters the resin column through the feed port, and after full contact with the resin bed layer, the specific components in the solution are adsorbed by the resin, so as to realize the separation of substances.
2. Elution: After the resin column is adsorbed, it needs to be eluted with eluent to replace the target substance adsorbed on the surface of the resin, forming an eluent containing high concentration of target substance.
3. Regeneration: After several cycles of adsorption and elution, the adsorption performance of the resin may gradually decrease. At this time, the resin needs to be regenerated to restore its adsorption activity.

• Pharmaceutical industry: used for the extraction and purification of active ingredients of traditional Chinese medicine, such as ginsenosides, flavonoids, alkaloids and other separation; can also be used for the purification of intermediates and raw materials of western medicine, remove impurities and isomers, improve the quality and efficacy of drugs.
• Food industry: can be used for the production of food additives, such as the extraction and purification of sweeteners, pigments, spices and so on; can also be used for the removal of harmful substances in food, such as the adsorption and separation of pesticide residues, heavy metal ions and so on, to ensure food safety.
• Environmental protection: widely used in wastewater treatment, such as adsorption to remove organic matter, heavy metal ions, dyes and other pollutants in wastewater, reduce the COD (chemical oxygen demand), BOD (biochemical oxygen demand) and color of wastewater, so that it can meet the discharge standards or reuse standards.
• Chemical industry: used for product separation and purification in organic synthesis reactions, such as catalyst recovery, organic intermediates refining; can also be used for chemical raw material pretreatment, remove impurities and harmful substances, improve the quality of raw materials and reaction activity.

• Efficiency: The resin column has high adsorption capacity and separation efficiency, which can quickly and effectively extract the desired substances from the mixture.
• High selectivity: the resin can selectively adsorb according to the molecular size, polarity, functional groups and other characteristics of the target substance, and has high affinity for specific substances.
• Good stability: Stainless steel resin column usually has good mechanical strength and chemical stability, can operate stably in a wide range of temperature, pressure and pH.
• Simple operation: The operation process of the equipment is relatively simple, easy to master and control. By adjusting the flow rate, temperature, pressure and other parameters of the inlet and outlet liquid, it is convenient to realize the adsorption, elution, regeneration and other operation processes.
• Reusable: The resin can be reused many times after proper regeneration treatment, which reduces production costs and resource waste.
