Key Features

Thermo Scientific™ Nalgene™ syringe filters are built to meet your lab’s clarification and sterilisation needs. Our filters are available in a variety of sizes and membranes that can be easily used for both sterile and non-sterile laboratory applications. Whether your research necessitates prefiltration, sample preparation, sterile filtration, laboratory filtration, or gas venting, Nalgene™ syringe filters are lab essentials.

• Inlet: Female Luer-Lok™, outlet: Male Luer slip
• Polypropylene housing with ID colour rings
• Pore size and membrane type printed on unit

Polyethersulfone (PES) membranes:

• Highest throughput and lowest clogging
• Low binding
• Most commonly used general purpose membrane

Surfactant-Free Cellulose Acetate (SFCA) membranes:

• Low protein binding, lower extractables than standard CA
• Good for cell culture fluids and cellular solutions
• Polypropylene housings with blue colour rings

Cellulose Acetate (CA) membranes:

• Some protein binding and extractables
• For sterile filtration and clarification of: buffers, aqueous solutions and reagents
• Polypropylene housings with red colour rings
• Nylon membranes:
• Naturally hydrophilic, low extractables, some protein binding
• Useful for alcohols, cryoprotectants such as DMSO and with aqueous/biological and weak solvents
• Polypropylene housings with pink colour rings

PTFE membranes:

• Naturally hydrophobic
• Excellent for HPLC/GC solvent filtration. Ideal for sterile venting of air or other gases during filtration
• Polypropylene housings with white colour rings
