Choosing the Best Syringe Filters for Biological Sample

protein samples were evaluated using HPLC/UV by comparing samples with or without filtration for their monomer, dimer, or aggregates peaks. In addition, syringe filter cleanliness was evaluated by filtering membrane-compatible solutions and monitoring the filtrate with LC/MS under positive and negative modes.

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.

Syringe Filters | Sigma-Aldrich

Sterile or Non-Sterile Syringe Filters. While the primary function of a syringe filter is to remove particulates from a liquid sample, you will select either a sterile or non-sterile filter, depending on the end application. Sterile syringe filters are used to sterilize non-sterile solutions or clarify sterile solutions.

Syringe Filter, Membrane Filter FQA - filtration solutions

The common membranes used for gas/air filtration are our hydrophobic Polypropylene and PTFE Membranes. They both inhibit the flow of water vapors (hydrophilic) while allowing regular air molecules (such as oxygen) to pass. For the PTFE membrane the water intrusion pressure (which is inversely related to pore size) is greatest with the smaller

FAQs - FILTRATION

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

Membrane Filtration: Choosing the Correct Type of Filter

Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach, minimizing time spent troubleshooting and maximizing efficiency.
