47mm In-Line Filter Holder, Polypropylene, Autoclavable, 1/Pk
GVS SKU: 1262579

Featuring a rugged polypropylene body that delivers a stable, leak-resistant platform for microfiltration with 47mm disc membranes, this in-line filter holder is built for ultra-cleaning and sterilizing liquids under positive pressure. The polypropylene construction provides a wide working temperature range and excellent chemical compatibility, while a simple hand-tightened locking ring seals the unit without tearing or twisting the membrane. The holder can be used for aseptic sampling of liquids or gases at point-of-use or when samples must be collected and processed on-site.

Key Construction Characteristics

• Polypropylene construction provides broad chemical compatibility and durability across a wide temperature range.
• Dual support screens allow flow in either direction for bi-directional in-line use.
• Exterior locking ring and inlet cap design let the unit be assembled quickly by hand without tearing the membrane.
• Three O-rings help prevent leaks with all membrane types.
• Autoclavable and able to withstand temperatures up to 121C.

Performance Notes

• Accommodates a standard 47mm disc membrane (membrane sold separately).
• Filters up to 1 liter depending on the viscosity of the sample.
• Conforms with EPA Method 1311 for the Toxicity Characteristic Leaching Procedure (TCLP), 40 CFR Part 261.

The combination of dual support screens, triple O-ring sealing, and a tear-free locking ring maintains membrane integrity through repeated assembly and use. The autoclavable polypropylene body withstands routine sterilization, supporting reliable, reproducible filtration while protecting sample integrity from setup through collection.
