Columns gauze tube

Montz, Gempak 2AT202,Ralu-Pack 250 YC, MeUapak 250 Y of sheet metal, plastic and gauze tube column with regularly stacked 25—50 mm Bialecki rings etc. 

An alternate method of applying countercurrent extraction is illustrated in Fig. 4-19. The extraction tube contains a series of agitators driven by a rotating central rod and separated by sections of wire gauze which act as phase separators. The solution is fed in at the center of the column, the heavier solvent is fed in at the top, and the lighter solvent is fed in from the bottom. The material in the solution is par-... 

The other characteristics of rotating columns are comparable to those of concentric-tube and multiple-tube columns, and of columns with wire-gauze or wire helix elements (sections 7.3.1 and 7.3.4). 

One way of maximising the area-to-volume ratio is to create a porous working electrode with a very large active surface. This can be achieved in various ways, e.g. use of stacks of metal gauze, sintered metal tubes, reticulated vitreous carbon or packed beds along the lines of HPLC columns composed of conducting material, such as carbon particles or silver granules. One method of construction is to fuse...
