Description

PALL AP-4791 Acrodisc PSF Syringe Filters with PTFE Membrane - GxF/0.2 µm (1000/pkg)Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build up and reduce system downtime. Sample filtration using syringe filters containing 0. 45 m (HPLC) or 0. 2 m (UHPLC) pore size membranes will also extend the life of chromatography columns

Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing.

PTFE membrane is highly chemically compatible for the filtration of harsh solvents that can destroy other membrane materials. PTFE is a hydrophobic membrane, so it will repel water and is not suitable for the filtration of aqueous solutions.

As well as being suitable for the filtration of organic solvents in applications such as HPLC and UHPLC sample preparation, the hydrophobic nature of the PTFE membrane makes these syringe filters ideal to use in gas filtration or as a moisture barrier in venting applications.

The GxF/PTFE membrane configuration features a a GxF multi-layer glass fiber prefilter, providing two to four times the throughput of standard prefilter devices. The multi-layer prefilter captures particulate rated from > 40 to 1 μm.

Always Reliable and Good Quality
I’ve always used Q-tips, and they’re just better than most other cotton swabs. The cotton stays in place and doesn’t fall apart easily, and the sticks are sturdy without bending too much.I use them for everyday things around the house, quick cleanups, and personal care, and they always work well. The 500 count box also lasts a long time.Simple product, but consistent quality every time.

Essential household item with great quality
These Q-tips cotton swabs are a household essential that I always keep stocked. The 100% cotton tips are soft yet sturdy and perfect for so many uses from beauty to first aid. The 500 count package is a great value and lasts a long time. I appreciate the quality and consistency of the original Q-tips brand. These are far superior to generic cotton swabs in terms of quality and durability.

I only trust Q-Tip brand!! Great product. Never had luck with generic swabs.
I only trust Q-Tip brand!! This is a consistently great product. I've never had good luck with generic swabs, they either bend, don't have enough cotton on the end, or fray as I use them. These are soft tips, yet the stick is firm enough not to bend. I'll always go with Q-Tips and this 500 pack is a great value.
