New long-life protection column comes outTime：2019-12-15 Zhansa officially launched a new type of long-life protection column. The protection column adopts an epoch-making adaptive structure, which can effectively compensate for the slight collapse of the column head during the use of the protection column. Its very simple and fast packing also adopts the wet method instead of the traditional dry packing of other guard columns, which can effectively protect the preparation column and reduce the frequency of packing. |
