Filter sheet
COEI-1-PLAQFI Depth filter sheets
- Objective, origin and scope of application
Depth filter sheets, belonging to the family of porous filter materials, are composed of organic and/or inorganic materials, and are generally used for clarification and/or microbiological stabilisation of liquids; their geometrical shapes are specific to the filtration systems defined by the manufacturers.
Perlite
COEI-1-PERLIT Perlite
CAS no.93763-70-3
Expanded perlite
- Object, origin and field of application
Perlite is a vitreous rock of volcanic origin, belonging to the rhyolite group. Like glass, perlite is made of aluminium silicate and has a chemically bound water content of 1% to 2%.
Oxygen
COEI-1-OXYGEN Oxygen
Egg (albumin of)
COEI-1-OEUALB Egg (Albumin of)
Ovalbumin
Albumen ovi
- Objective, origin and scope of application
The albumin of an egg is obtained by desiccating fresh egg whites. It is found in the form of a fine, white, very light powder which is not completely soluble in water, but is soluble in certain alka
Metatartaric acid
COEI-1-METACI Metatartric acid
Ditartaric acid
Acidum ditartaricum
SIN N°. 353
- Objective, origin and scope of application
Nanofiltration membranes
COEI-1-NANMEM Nanofiltration membranes
- Object, origin and scope of application
Membranes belonging to the family of semi-permeable membranes, these can be homogenous or composite membranes and are generally organic; they may have a spiralled or "spiral-wound", flat sheet or "frame and plate", tubular or hollow fibre configuration.
Ultrafiltration membranes
COEI-1-MEMULT Ultrafiltration membranes
- Object, origin and scope of application
Membranes belonging to the family of porous membranes, these can be organic or inorganic, and are generally anisotropic (asymmetric) or composite membranes; they may have a spiralled or "spiral-wound", flat sheet or "frame and plate", tubular or hollow fibre configuration.
Bipolar electrodialysis membranes
COEI-1-MEMBIP Bipolar electrodialysis membranes
- Object, origin and scope of application
A bipolar membrane is a thin, dense, insoluble wall composed of a polymer material functionalized by ionic groups. A bipolar membrane has an anionic face and a cationic face; it is equivalent to combining a cationic membrane and an anionic membrane into a single membrane.
Reverse osmosis membranes
COEI-1-MEMOSM Reverse osmosis membranes
- Objective, origin and scope of application
A reverse osmosis membrane is a membrane belonging to the group of semi-permeable thin-layer composites (known as TFC, or Thin Film Composites).
Electrodialysis membranes
COEI-1-MEMELE Electrodialysis membranes
- Objective, Origin and Scope of Application
An electrodialysis membrane is a thin, dense, insoluble wall composed of a polymer material that is permeable to ions. When placed between two solutions, it allows the selective transfer of ions from one solution to the other when acted upon by an electric field.
