Common use 0.2 um ptfe filter for solvent prefiltration

Filters are packaged into separate tubes to protect them from external sources of extractables. While one tube is in use, the others are kept sealed. Excellent chemical resistance. Use this universal filter for all your LC-MS samples. The WWPTFE (water wettable polytetrafluoroethylene) membrane can be used with both organic and aqueous solvents.

Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.

Target2 PTFE Syringe Filters are used for general biological filtration. They are especially well-suited for applications where high protein recovery is desired. Target2 Syringe Filters are an ideal choice for general purpose laboratory use. Robust and reliable, they deliver excellent performance at an attractive price. Outstanding Performance

What membrane filter pore size should I use for sterilization? Regardless of the membrane filter material, always use a 0.2 µm pore size membrane filter as the final filter for any sterilizing filtration. The 0.2 µm membranes used in Thermo Scientific™ Nalgene™ filters have been tested and shown to retain 100% of a challenge of 1 X 107

very good chemical resistance to a broad range of solvents including all common solvents used in HPLC (methanol, acetonitrile, water). 6874-2502 PTFE 0.2 150 ...

the device against overfilling, the labForce™ Pipette Controller is equipped with a 0.2 um PTFE filter. The filter, the pipette holder and the nosepiece are autoclavable. Includes a universal battery charger, an additional hydrophobic 0.2 µm filter and a two-position charging stand. Related Products: Pipette Controller

biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.

This 25 mm Millex® syringe filter with a Hydrophobic PTFE membrane, for non-sterile filtration, has a 0.2 µm pore size used in fine particle removal from organic solvents.
