solvent compatibility ptfe membrane filter 0.45um for hplc

The built in 0.45µm PTFE (Teflon) membrane is made with very high purity materials and has extremely low extractables. This unit is the choice of many laboratories working with agressive, organic solvents that desire faster filtration than using traditional 47mm membranes. Use with house vacuum or vacuum pumps and filter directly into any HPLC solvent reservoir bottle that has GL-45 screw threads to very quickly and easily filter and degas your HPLC solvents right into your mobile phase

0.22 μm hydrophilic PTFE membrane filter bubble points are above or equal 0.1MPa and 0.06MPa respectively, diameters ranging from 13mm, 25mm, 47mm to 90mm, 142mm, 293mm. Hydrophilic PTFE membrane pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents.

Nylon and PTFE (Teflon) membranes have broad chemical compatibility and can be used to filter most HPLC and GC fluids/solvents. PTFE can also be used to filter air or gases. Nylon is good for DMSO. PES and CA/SFCA membranes are compatible with non-alcoholic aqueous solutions and

The low-binding PTFE membrane is the best option for leachable free filtration whenever highest chemical compatibility and pH values of 1 - 14 are needed. For hydrophilic solutions pre-rinsing with a solvent is necessary to make the hydrophobic membrane permeable for aqueous liquids.

PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals.. Review the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products in the cart below.

PTFE Syringe Filter Polypropylene Housing: Pore Size: 0.45um PTFE membrane filter for hplc Whatman. Discounting solvent compatibility PTFE membrane filter for sale.

PP membrane is suitable for organic solvents, and is very suitable for HPLC mobile phase filtration and degassing especially acetonitrile. 0.45 membrane filter has a long service life, is suitable for position difference filtration, high-viscosity, multi-suspended matter sample filtration, and the filtration accuracy is stable and reliable.

13 mm Acrodisc syringe filters are designed for the filtration of sample volumes up to 10 mL. They feature an effective filtration area of 1.0 cm 2 and a polypropylene housing which has excellent chemical compatibility properties. The syringe filters are HPLC certified for low levels of UV-absorbing extractables, preventing spurious peaks on

In most cases, CHROMAFIL filters will have only short contact with a solvent. In these cases they may be used despite limited compatibility. For example, a PTFE filter with PP housing does not liberate any UV-detectable substances during filtration of 5 ml THF, although PP shows only limited resistance towards THF.

relate to a membrane that may respond almost immediately to immersion in solvent. In addition, solvent-membrane compatibility requires additional consideration of filtration-specific factors. None of these published compatibility guides, for example, monitors the solvent’s ability to wet a membrane or increase extractables. 4.

Nov 03, 2020 · 0.45um hydrophilic PTFE syringe filters all use high-quality microporous membranes, which have low sample adsorption and ensure maximum recovery of small or high-value samples. The housing of the 0.45um syringe filter adopts high-density polyethylene material with low dissolution and good chemical compatibility.

Membrane Material Millipore LCR PTFE; Pore Size (µm) 0.45; Membrane Diameter (mm) 13; Housing Material High-density Polyethylene (HDPE) Description HPLC Certified Syringe Filter, LCR PTFE, 0.45um, 13mm dia, 100/pk

PTFE syringe filters are made of Polytetrafluoroethylene (PTFE) membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes
