Syringe Filters for HPLC & Sample Preparation | analytics

Pore Sizes and Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.

PTFE Syringe Filters, 0.45μm, 25mm, Hydrophobic, Non-sterile

All the syringe filters are HPLC certified. Hydrophobic PTFE syringe filters have broad chemical compatibility, high pH resistance.. They are versatile filters for use with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation.

Membrane Filters for Lab Filtration | analytics-shop.com

PTFE membranes are extremely resistant to aggressive solvents and acids and can be used to filter particulate from both liquid and gas samples. Regenerated Cellulose (RC) Regenerated cellulose membranes are resistant to solvents and are hydrophilic. 0.45 μm pore size is typically used for HPLC sample preparation.

Laboratory filtration

Membrane filters are generally described as screen filters because particles are almost entirely trapped on the filter surface. The narrow effective pore size distribution of Whatman membrane filters is one of their major features. Whatman cellulose filter papers exhibit particle retention levels down to 2.5 µm.

Whatman PTFE Membrane Filters - Camlab

The 0.45µm pore size is normally used for HPLC applications. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membrane filters and their ability to stop aqueous aerosols. Pore sizes of 0.2µm and 0.45µm are typically used in these tasks.

Membrane Filters, Whatman WTP (PTFE) | General Laboratory

One of the major applications for the PTFE (Type WTP) filter is the clarification of corrosives, solvents and aggressive fluids. This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.5µm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE

Whatman PFTE Membrane Filters ‒ TE Range | Cytiva, formerly

Whatman PTFE membrane filters from Cytiva's business are chemically stable and inert, making them suitable for use with aggressive organic solvents, strong acids, and alkalis. The TE range features polypropylene support material for improved strength and handling Temperature resistant up to 120°C

Whatman™ 7585-004 Grade WTP Plain White PTFE Membrane Filter

The 0.5 µm pore size PTFE membrane filter is normally used in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. Whatman™ Grade WTP PTFE membrane filters are an excellent choice for use with aggressive solvents liquids and gases that can attack other membranes.
