Are Nylon Syringe Filters Compatible with Chloroform?

No. Nylon membrane syringe filters are generally not recommended for use with chloroform or other halogenated solvents.

Nylon membranes may experience chemical compatibility issues when exposed to:

• Chloroform
• Methylene chloride
• Carbon tetrachloride
• Other halogenated solvents

Nylon membranes are also not recommended for use with:

• Strong acids
• Acid concentrations of approximately 1N or greater

Using incompatible solvents may affect membrane integrity, filtration performance, and analytical reliability.

Recommended Alternative for Chloroform Filtration

For samples containing chloroform or other halogenated solvents, PTFE (Polytetrafluoroethylene) syringe filters are generally the preferred choice.

PTFE membranes offer:

• Excellent chemical resistance
• Broad organic solvent compatibility
• Compatibility with halogenated solvents
• Low extractables for analytical applications

These characteristics make PTFE syringe filters a common choice for HPLC, GC, and laboratory sample preparation involving aggressive organic solvents.

Key Takeaways

• Nylon syringe filters are not recommended for chloroform.
• Nylon membranes are generally unsuitable for halogenated solvents.
• Nylon membranes are also not recommended for strong acids.
• PTFE syringe filters are typically the preferred alternative for chloroform-containing samples.
• Always verify membrane compatibility before sample filtration
