Thermo Filter Unit 115 ml .45 um PES Filter and Receiver Total of 12 Filters

Thermo Scientific Nalgene 115 ml Filter and Receiver Unit (0.45 µm PES)

The Thermo Scientific Nalgene 124-0045 is a complete, disposable vacuum filtration system designed for the rapid clarification and bioburden reduction of laboratory fluids. This unit features a 115 ml capacity upper filter funnel and a matching 115 ml receiver bottle, integrated with a high-performance 0.45 µm Polyethersulfone (PES) membrane. The PES membrane is specifically engineered for "fast-flow" applications, providing exceptional throughput and ultra-low protein binding, which ensures maximum recovery of critical sample components. Delivered sterile and individually wrapped, the 124-0045 is an essential tool for laboratories processing small volumes of cell culture reagents, buffers, and protein-rich solutions where efficiency and sample integrity are non-negotiable.

Technical Performance and Design

• Fast-Flow PES Membrane: The 0.45 µm Polyethersulfone media offers significantly higher flow rates than cellulose acetate or nylon, allowing for rapid filtration of aqueous solutions with minimal clogging.

• Low Protein Binding: The membrane's hydrophilic chemistry minimizes the non-specific adsorption of proteins, enzymes, and growth factors, making it ideal for the filtration of serum and media supplements.

• Secure Receiver Storage: The receiver bottle features an ergonomic shape and a leak-proof screw cap, allowing the filtered filtrate to be stored in the same vessel used for filtration, reducing the risk of contamination.

• Vacuum Port Integration: Features a standardized quick-disconnect vacuum port with a high-efficiency cellulose plug to prevent contamination of the vacuum line during operation.
