This filter holder is well suited for particle removal from samples and reagents for analytical methods, such as NMR samples as it is unaffected by chemicals and contains no trace elements which could be released into the liquid being filtered.
This polycarbonate filter holder has been designed for the use of 25 mm filters for the filtration of aqueous solutions.
This polycarbonate filter holder has been designed for the use of 13 mm filters for the filtration of aqueous solutions.
16214 is recommended for the filtration of volumes of up to about 100 ml.
Made of stainless steel, this holder is heat resistant and the chemical compatibility depends on the inserted filter type only.
Re-usable syringe filter holders are available in Stainless steel, Polycarbonate or PTFE for the use of 13 or 25 mm Filter.
The hydrophilic cellulose acetate membrane filters combine high flow rates, good chemical resistance (pH 4-8) and thermal stability with very low adsorption characteristics. They are excellently suited for use in pressure filtration devices.
The cellulose nitrate (CN) or also called mixed cellulose ester (MCE) membrane filters are composed of cellulose nitrate and a small content of cellulose acetate. They are recommended for a broad range of applications like the filtration of aqueous solutions or for sample preparation.
The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.
Polyamide membrane filters are hydrophilic and chemical resistant to alkaline solutions and organic solvents.
Polyethersulfone membrane filters are hydrophilic, have high flow rates, a low non-specific protein adsorption and are chemically resistant over a pH range of 1 – 14.
The white and hydrophilic polycarbonate track-etched membrane filters are manufactured from high grade polycarbonate film using track-etched technology.
The regenerated cellulose membrane filters are made of regenerated cellulose reinforced with a cellulose nonwoven.
