Pre-sterilized Nylon-66 Membrane Syringe Filters

The Pre-Sterilized Nylon-66 Membrane Syringe Filters from Scilabex are designed for precise and contamination-free filtration in critical laboratory and pharmaceutical applications. These advanced laboratory syringe filters offer excellent chemical compatibility, low extractables, and validated bacterial retention for reliable sterile filtration.

Widely used across the USA and global laboratories, these filters are ideal for applications requiring high purity, minimal sample loss, and consistent performance.

What are Pre-Sterilized Nylon-66 Syringe Filters?

These syringe filters are gamma sterilized and ready-to-use filtration devices featuring a hydrophilic Nylon-66 membrane. They provide efficient removal of bacteria and fine particles while ensuring minimal interference with the sample.

They are commonly used for:

• Sterile filtration of biological and pharmaceutical samples
• Chemical and solvent filtration
• Critical lab and research applications

Applications

The Pre-Sterilized Nylon-66 Membrane Syringe Filters are widely used in:

• Sterile filtration of DMSO for cryo-preservation of stem cells
• Particulate removal from pharmaceutical parenterals before administration
• General sterile filtration in laboratory environments

These filters are ideal for both biological and chemical applications.

Special Features

• Absolute retention for reliable sterilization
• Low hold-up volume for minimal sample loss
• Minimum back pressure for smooth filtration
• Extremely low extractables for accurate results
• Hydrophilic membrane – no pre-wetting required
• Wide chemical compatibility
• Heat sealed to ensure ‘no leaching’
• No initial flushing required
• Validated for bacterial retention as per ASTM F838
