PTFE Syringe and Vent Filters - Sterlitech non-sterile PTFE syringe filters stand up to the most aggressive solvent, acid and base Yes, for water and some aqueous solutions, a hydrophobic membrane syringe filter installed in the tubing between the vacuum pump
Captiva syringe filters are typically used to prepare small-volume samples for HPLC and ion chromatography. They allow for high flowrates and loading volumes, and also extend column lifetimes considerably. Find out more here.
Cytiva. a PTFE membrane that provides highly efficient filtration in a very small area. Capsules with 1.0 µm pore size are supplied with a solvent-resistant polypropylene prefilter for extended life and are intended for use with highly contaminated solutions. The 0.05 and 0.1 µm filter devices.

Replaces SLLGH25NK, 0.20 µm pore size, 33 mm diameter, Millex-LG hydrophilic PTFE membrane. All Photos ( 1) eCl@ss: 32031690. Pricing and availability is not currently available.
This technique can be used for most membrane filters with a single refractive index. The refractive index for Durapore membrane is 1.42 and for MF membrane its 1.50. Please note that this does not work for polycarbonate membranes because these membranes have more
Choose a filter or membrane based on: 1) Chemical compatibility of the membrane and housing with your sample matrix. 2) Size and amount of particulates in the sample. 3) Potential interactions (binding) between the membrane and sample components. 4) Special considerations such as requirement for prefilter or inorganic ion certification.
Glass fiber filter papers are commonly used as pre-filters in many filtration devices and for filtration of viscous or otherwise hard-to-filter samples with high solids content. These hydrophilic filters feature high-dirt loading capacity, and excellent compatibility with organic solvents and acids.
