Description
Compatibility

Available in stainless steel with luer fittings for use with a standard syringe.

The holders are designed for the quick and easy clarification, sterilization, and removal of particulates from small volume samples, typically for HPLC applications. The holders contain PTFE gaskets and O-rings and allow the membrane to be autoclaved in place without the filter sticking to the holder.

Luer lock fittings connect to a standard syringe and offer convenience and ease of use for clarification, sterilization, and removal of particulates from small volumes of liquid (e.g., HPLC samples and solvents).

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.

Membrane Material

PVDF	Low	Hydrophilic	Medium	Filtration of protein solutions
NYL	Medium	Hydrophilic	Medium	Filtration of aqueous and solvent/aqueous mixtures
CA	Low	Hydrophilic	Low	Filtration of protein solutions
CN	High	Hydrophilic	Low	Filtration of aqueous solutions where protein binding is not a concern and microbioloigical applications.
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.
