Stainless steel holders differ in hopper capacity (300 ml, 500 ml or 1000 ml) and valve type. They are specially designed for applications in which particles or microorganisms need to remain on the surface of membrane filters. The stainless steel frit ensures a uniform distribution of retained particles over the entire surface of the membrane filter. Special features make it easy to use these filter holders during routine testing. Easy to handle with a single clamp for secure attachment or convenient funnel removal.

High-quality, corrosion-resistant in-line filter holder is designed for stack sampling.

• Membrane or glass fiber filters
• Holder opens and closes easily
• Filter remains undisturbed for particulate analysis
• Upstream threaded vent allows release of trapped gas during liquid filtration

Body, center ring collar, support screen, and underdrain disc are made of Type 316 stainless steel. Captive thrust ring is PTFE; O-ring is Viton® rubber; hose barb adapters are polyethylene. Inlet/outlet connections: 9.5 mm (3/8") FNPT. Hose barbs accept 6.4 mm (1/4") I.D. tubing. Autoclavable.

Product Description:
• 47mm filter diameter
• Available in type 304ss or 316ss
• Filter liquids or gases at point-of-use
This 47mm in-line holder (Model IFH47) is available in both type 304 or 316 stainless steel. The

PTFE coated support screen prevents the sticking of the membrane during autoclaving. The back-
pressure support screen protects the filter from rupture during reverse pressure surges. Upstream

vent enables venting at any time during filtration. The dual sealing system compresses filter to ensure

no lateral wicking/leaking.

The locking ring enables filter changes without disconnecting from lines. Unit comes standard with silicone o-
ring and FPM vent o-ring. When filtering gases, it is recommended that a second support screen be used

upstream of the membrane. Replacement parts and alternate o-ring materials are available.

Applications:

Sterilize and ultraclean liquids and gases under positive pressure. Sterilize with membrane in place for microbiological studies.
Install for point-of-use filtration on filling machines. General particulate analysis
