Sterile Syringe Filters, Hydrophobic PTFE, 25mm, S2636-11-50EA, i-Quip (CAT#: STEM-GC-1426-Y)

Needle filter shell is made of polypropylene plastic, the upper and lower part is welded together by ultrasonic waves, which is the preferred method for filtering small amount of HPLC and GC samples.

Membrane Material: Hydrophobic PTFE
Pore Size: 0.22μm
Filter Dia.: 25mm
Package: 1 box (50 pcs)

Polyvinylidene fluoride (PVDF) membrane: minimum protein binding, for aqueous and mild organic solutions.
Hydrophobic PTFE membranes: compatible with more aggressive organic solutions and can also be used to filter aqueous solutions
Nylon membranes: have broad chemical compatibility for filtration of aqueous and organic solutions.
Hydrophilic PTFE membranes: with low protein binding rate.
MCE membranes: used for filtration of water, buffers, and salt solutions.
Polyethersulfone (PES) membranes: for ultrafast filtration of tissue culture media, additives, buffers and other aqueous solutions.
Cellulose acetate (CA) membranes: Excellent for filtration of biological/immunological samples, cell culture media components, and most other aqueous solutions and reagents.
