Membrane Types & Applications :

Nylon 66

• hydrophilic membrane
• filtration rate: fast
• strong protein binding capacity
• solvent compatibility: “weak” organic solvents (alcohols, acetonitrile), aqueous solutions, base solutions, THF
• not recommended for: strong acids, halogenated hydrocarbons
• use: for general filtration and filtration of HPLC samples

PTFE

• hydrophobic membrane
• filtration rate: medium
• low dissolution, best solvent resistance
• solvent compatibility: “strong” organic solvents, strong acids, strong alkalis, chlorinated hydrocarbons
• not recommended for: aqueous solutions
• use: for organic solvents, general filtration and filtration of HPLC samples

M. E. Cellulose (mixed cellulose ester, nitrate and acetate)

• hydrophilic membrane
• filtration rate: medium
• solvent compatibility: aqueous solutions, ”weak” base solutions, hydrocarbons
• not recommended for: ”strong” organic solvents, strong acids, strong bases
• used for the filtration of aqueous solutions, biological samples and HPLC samples

• 13mm S. S.316 Filter Holder
• HPLC Needle
• 5ml Gas Tight Syringe
• Nylon 66 Membrane Filter13mm x 0.2μ (Pk. of 100 Nos.)
