2016/3/22 · PVDF Polyvinylidene fluoride. PVDF (polyvinylidene fluoride) is a hydrophobic, solvent resistant membrane that exhibits low levels of UV absorbing extractables. PVDF is useful for HPLC sample filtration, as well as general biological filtration. PVDF is considered to be one of the lower protein binding membranes.

The polar fractions containing GDGTs were filtered through a 0.45 μm Teflon syringe filter and dissolved in 99:1 hexane: isopropanol for analysis on an Aijiren series high-performance liquid
• Millex-LCR filter contains a Millipore-exclusive hydrophilic PTFE membrane and are HPLC-certified for low levels of UV-absorbing extractables. They provide the cleanest sample for HPLC analysis. • Durapore® (PVDF) filters combine fast flow with
Organic acids in wines were analyzed by high-performance liquid chromatography (HPLC) (Dionex IC-500, Milano, Italy) using a system with diode array detection (DAD), column Aminex HPX-87H (9 µm
PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media solutions.
2018/11/15 · Before use, all solvents were filtered through a 0.2 µm filter from Sartorius Stedim (Goettingen, Germany), and before HPLC analysis, all samples were filtered through a 0.2 µm single use syringe filter from Phenomenex (Bologna, Italy). 2.5. Statistical analysis
The 1‐mL volume of the concentrated extract was filtrated through a 0.20‐μm syringe filter into an Eppendorf tube for the HPLC injection. Instruments The SHISEIDO SP^LC chromatographic system was equipped with a SP3201 pump, an SP3023 autosampler system and a programmable SP3213 fluorescence detector (Shiseido, Tokyo, Japan).
4.13.4.2 Using Filter Membranes for Increased Diffusion Filter membranes are also used as culture substrates to support the long-term viability of tissue slices and layers of cultured cells. Unlike nonporous culture surfaces, culture medium can diffuse through porous filter membranes and cellular waste products can diffuse away from the cell mass into the membrane.
The 305/306 Pumps can be used in either isocratic or gradient HPLC with a wide range of flow rates from 10 µL/min to 200 mL/min. Simple Control Achieve reliable chromatographic separation with the 305 and 306 Pumps using easy method development through TRILUTION® LC software or using a standalone keypad, depending on the model.
The pores of an HPLC syringe filter will typically be 0.2, 0.22, or 0.45 µm in size. Syringe filters utilize different polymer membranes depending on the intended application; hydrophilic materials like nylon, MCE, and PES should be used for purifying oils or alcohol, whereas hydrophobic membranes like PTFE-B or PVDF are best applied to organic solvents, gases, or vapors.
