How to better understand the Resin column Ion exchange column? 
An ion exchange column is a columnar pressure vessel used to perform ion exchange reactions, and is the exchange equipment for the tube-column method of ion exchange. It is often used in laboratory and industry. According to the regeneration method, it can be divided into three types: in vivo regeneration mixed bed, in vitro regeneration mixed bed, and anion resin external transfer regeneration mixed bed, and it can be divided into laboratory ion exchange columns and industrial ion exchange columns in terms of the scope of use.
The English name of ion exchange column is ion exchange column, which is equivalent to the ion exchange resin in the column to exchange with the solution in multiple batches, and the exchanged solution is separated from the ion exchange resin in time. The composition of the solution flowing through the ion exchange resin bed changes with time and bed height. This method is highly efficient and widely used in production. This equipment is mainly used in electric power, electronics, chemical industry, medicine, light industry, textile, metallurgy, national defense and other industries, pure water preparation, hard water softening; separation and purification of rare elements; food, drug decolorization and purification; chemical raw materials, extraction, refining, recycling; a variety of wastewater treatment.
Wenzhou City Sauter Pharmaceutical and Chemical Engineering Co., Ltd. manufacturing this equipment in strict accordance with the "steel welded atmospheric pressure vessel", "pressure vessel", "fixed pressure vessel safety technology supervision regulations" and "Drug Production Quality Management Code" GMP for design and manufacturing.
The resin column can be equipped with control system according to customer's requirements. The control part of this chromatography column includes liquid level display control. The liquid level display is installed on the side of the tank (glass plate liquid level meter), and the liquid level can be observed directly from the mirror.
The column and its accessories (such as sight glass, import and export, etc.) are reasonably distributed, so that both observation and operation are simple and easy. Please contact us for more information:
