Syringe Filter(Hydrophobic polyvinylidene fluoride)

A syringe filter (sometimes called a wheel filter if it has a wheel-like shape) is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe filter.

0.45um Hydrophilic PTFE Syringe Filters Can Effectively Filter

Mar 11, 2020 · 0.45um syringe filter which is also called a wheel filter because of its wheel-like shape is a disposable membrane based cartridge filter. Widely used in labs for quick and efficient filtering, material purification, and sterilization for solutions <250mL, it can be attached with a syringe and remove impurities in liquid solutions.

PVDF Membrane Filters. PVDF (polyvinylidene fluoride) is a hydrophobic, solvent resistant membrane that is known for it's high temperature resistance and high particulate removal efficiencies. PVDF is commonly used in the offshore oil and plumbing industries, and is suitable for Gas, Vapor, High-Temperature, Food, and Medicine Filtration.

Application Note Multisample filtration of small volumes

When filtering a few samples at a time, syringe filters are commonly used. Syringe filters are available in various sizes, enabling filtration of very small sample volumes without losing significant sample to hold-up. Syringe filters prove less efficient for users typically filtering 10 – 100 samples a day (65 – 70% of users). For these

HPLC Method for the Simultaneous Determination of the UV

Aug 24, 2013 · Before samples were injected onto the HPLC, they were filtered through a 15 mm syringe filter with a 0.45 μm PTFE membrane (Phenomenex Inc. Sydney, Australia). Standard Solutions For linearity determinations, standard solutions for BMDM and OC were prepared in the concentration range of 20.0–100.0 μg mL −1 .
