Simultaneously filter and degas HPLC solvents to ensure the best conditions for your chromatograph. Solvent IFD has a 0.2?m high-flow nylon membrane for eluents that contain organic solvents (minimum of 80%) while Aqueous IFD has a 0.2?m hydrophilic nylon membrane and suitsaqueous-based mobile phases. Compatibility Guide to?Syringe Filter Properties Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each syringe filter contains a membrane filter of a set diameter and plastic housing with luer connections used for connecting to syringes (or in-line hosing systems). The membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate for your application and what diameter filter is suitable for your sample volume.?

RC Low Hydrophilic Medium Filtration of aqueous and organic solvents and protein recovery applications. Filter diameter? High particulate loaded samples with tend to block the pores in the membrane more quickly so the total volume you can filter through a certain diameter syringe filter will vary greatly. Please take the below figures as a guide only. 13mm diameter - for samples <10ml 25mm diameter - for samples <100ml 33mm diameter - for samples <250ml? For samples that are very particle ladden, it is recommened that you try pre-filtering your sample. Pre-filtering can be achieved with a number of different filters, such as glass microfibre. Some syringe filters come with an in-built pre-filter.? Feefo Reviews
