0.1~10.0 Micron Nylon Microfiltration Membrane

Introduction

Nylon microfiltration membrane is made of aliphatic nylon with good hydrophilicity, suitable for organic solvents such as alcohols, hydrocarbons, ethers, esters, ketones, benzene and its homologues, dimethylformamide, dimethyl maple, etc. It is one of the widely used microfiltration membranes and belongs to the terminal filtration membrane.

Parameters

Optional diameter: 13mm-800mm

Optional pore size: 0.1um, 0.22um, 0.45um, 1.0um, 5.0um, 8.0um, 10.0um

Material: Nylon (N6, N66), commonly known as organic membrane or oily membrane

Maximum working temperature: 60°C

Features and Benefits

• Nylon membrane is hydrophilic with high chemical compatibility, can sterilize and remove impurities.
• Can filter appropriate concentrations of acidic and alkaline solutions.
• Generally used for partial organic solvents and aqueous solutions, not suitable for filtering corrosive solvents and strong acidic or alkaline solutions.

Precautions of Nylon Microfiltration Membrane

• If filtered for a short period (several hours), this product is resistant to 20% concentration of formic acid, 30% HCl content of hydrochloric acid, and other acids of similar acidity, as well as 3% sodium hydroxide concentration of alkali. However, prolonged contact with the above concentrations of acids and alkalis will cause the nylon amide bond to break and the membrane to become brittle, so it should only be used at the lower limit of the above concentrations of acids and alkalis, and the lower the temperature, the less brittle it becomes when encountering acids and alkalis.
• Before use, the product should be cleaned by soaking in distilled water and then installed in the filter. For organic solvent filtration, soak and clean with ethanol.
• In situations where high demands are required, such as filtering chromatographic samples or reagents, if it is a water-based system, after cleaning with distilled water, pre-filter with distilled water. If it is an organic system, soak the product overnight in pure toluene and ethanol of over 95%, then pre-filter with pure toluene and pure ethanol after thoroughly washing the membrane. After cleaning the membrane thoroughly, use it.

Selection Reference for Filter Membranes: (Specifically Depends on Chemical Compatibility)

• For hydrophilic samples suitable for filtering water-based solutions, choose hydrophilic membrane discs. Available membrane discs include: CN-CA (water membrane), PES membrane, nylon membrane, PP membrane, etc.
• For highly corrosive organic solvents: choose membranes such as PTFE.
• For protein solutions, choose membranes with low protein adsorption, such as CN-CA, PES, PTFE, and PVDF hydrophilic membranes.
• For ion chromatography: generally choose PES filter membranes.
• For gas and steam filtration, choose hydrophobic membranes such as PTFE or PVDF.
• For high-temperature liquids, choose PES filter membranes, PVDF hydrophilic, or PTFE hydrophilic membranes.
