Allschoolabs Regenerated Cellulose (RC) Syringe Filters – Sterile and Non-Sterile

Syringe filter thats typically used for HPLC sample preperation. Suitable for cell removal in liquids, and the filtration of samples in aqueous solutions in organic solvents. Available in sterile and non-sterile forms Measure of diffusion of light Hydrophilic membrane Good mechanical resistance and weak absorption Bubble point : 10-15psi (0.45?m) 19-22 psi (0.22?m) Resistance against most of organic solutions Chemical compatibility : pH 3-12 Made from regenerated cellulose 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 Related Blogs Syringe filters - which one do I need? Syringe filters are used to help filter samples containing solid particles, into sample tubes for analysis. These work by using a membrane with a particular pore size to catch any solids within the samples. The Allschoolabs choice coloured filters are available with two different pore sizes, and in three different membrane sizes. Some of these filters come with pre-filters to catch any large particl...2 years ago More Information More Information MaterialRegenerated Cellulose
