DESCRIPCIÓN GENERAL
DESCRIPCIÓN GENERAL
The cell essentially consists of a transparent polycarbonate chamber which has a piston assembly fit to the top and a double flange base fit to the bottom.  Three (or six) simple thumbscrew are used to clamp the upper part of the cell to the base, which make assembly and disassembly a very quick and simple operation. The base of the cell has four inlet points for top and drainage/back pressure, cell pressure and bottom drainage/pore water pressure. 
Base adapters, plinths, top caps, porous disc, rubber membranes and sealing rings are not included.
See accessories.
