Syringe Filter Millex-CR, 13 mm, PTFE, 0.45 µm, non-sterile, hydrophilic, 100 pc/PAK

Lowest extractables, optimizing background levels of sensitive analyses like UHPLC and LC-MS
Filtration of protein-containing aqueous or organic solutions
Available in 0.20 μm and 0.45 μm pore sizes and three diameters to suit your application needs
Polypropylene housing material offers low levels of extractables and broad chemical compatibility.

Sterile Millex filter units are available in a larger 33 mm housing with either MCE, PVDF or PES membranes.
Faster flow rate:
The larger filter surface area increases flow rate and throughput. It also makes it easier to filter solutions because it reduces the pressure required to empty the syringe.
Higher operating pressure:
Millex filters have a maximum housing pressure of 10.5 bar (150 psig), which means you can filter solutions faster than before.
Color-coded:
The color-coded band on the Millex housing clearly indicates which membrane is inside.
