KC pore-water pressing bench, stainless steel cylinders

22.200 - Pore water pressing bench - Stainless steel
22.200 SS - Pore water pressing bench with stainless steel cylinders:

The KC Pore water pressing bench allows pore-water extraction of any kind of sediments, from sediments rich in organic material, to sandy sediments.

Sediment cores are segmented and placed in the pressing house, which is closed by means of the handle on top of the house. An over-pressure is applied (fed-in) at the reduction valve and the valves of the houses in operation are opened. The resulting compression of the sediment matrix leads to expelling of the pore-water, which is sampled in containers beneath the pressing house. Operation in a glove bag prevents atmospheric contamination with, for example, oxygen, so anaerobic analysis of the pore-water is possible.

The cylinders and all accessories are also available as AISI 316 stainless steel for special purposes. The water will be in contact with stainless steel only. See ordering details below. The cylinders will also fit on previous delivered models.
