Syringe Filters for Organic Solvents

Compatibility between your syringe filter’s media and the organic solvents you are filtering is of utmost importance when performing any type of application.

Not all syringe filter membrane materials are recommended for all substances and chemical reagents. For example, some solvents may eat away certain membrane materials. With other syringe filters, certain solvents may make the membrane unstable or change the physical properties of your sample.

It’s always best to do a trial test to ensure the syringe filter is compatible with the solvents you will be using for your process or application.

This article provides a guide to syringe filters for organic solvents, with categories that indicate which syringe filters are not recommended for or have limited use with certain substances and chemical reagents.

Organic Solvents Overview

In general, solvents are substances that can dissolve or disperse one or more other substances.

Organic solvents, according to the National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention (CDC), are carbon-based solvents, which means they contain carbon in their molecular structure.

Each organic solvent has its own characteristics, such as molecular weight, density, boiling point, melting point, solubility in water, and flash point.

Various classes of chemicals can be used as organic solvents, some of which NIOSH recognizes as carcinogens.

Organic solvents can be found in various consumer products, such as paints, glues, cleaning agents, adhesives, lacquers, etc.

Other organic solvents are used to produce plastics, textiles, agricultural products, printing inks, dyes, and pharmaceutical products.

Chemical Reagents Overview

A reagent is a substance used in combination with other substances to create a chemical reaction in order to detect, examine, analyze, measure, or produce other substances.

In a laboratory setting, reagents are used to provide better accuracy, reproducible performance and separation, consistency, and lower detection limits.

Syringe Filters With No or Limited Use With Organic Solvents or Chemical Reagents

This section lists the type of syringe filter membrane materials that have limited to no use with organic solvents.

Each category is followed by the organic solvent, which includes acids, alcohols, alkalines, esters, hydrocarbons, halogenated hydrocarbons, ketones, nitrogen, oxides-ethers and other substances, that either should not be used or are limited in use with the indicated syringe filter.

Syringe filters that fall under the not recommended category mean the filter’s membrane material is unstable in the presence of these organic solvents and chemical reagents.

Syringe filters listed under the limited use category mean the filter’s membrane material may be used in short-term, noncritical applications due to moderate changes in physical properties that may impact your sample.

NOTE: This information may not be inclusive of all organic solvents, reagents, and other substances, so it’s best to either do a trial test or contact us for complete information.
