GVS PORETICS Filter, Disk, PCTE Hydrophilic, 3.0µm, 47mm, 100/PK 1215036

The Gravi-Seal PS Analytical Filter Holder (complete unit) is a two-piece, polysulfone laboratory filtration funnel designed for gravity-assisted analytical filtration of aqueous samples. It accepts a 47 mm depth filter disc and mounts with a No. 8 stopper into a standard 1-liter filtering flask or into multi-place stainless steel manifolds for concurrent tests. The unit is autoclavable and intended for applications such as sterility testing, particle removal, cell culture, and microbiological sample filtration.

Key Features:

• Accepts 47 mm depth filter disc
• Complete unit: funnel, base and No. 8 stopper; single unit pack (1/PK)
• Housing material: polysulfone (PS), autoclavable and chemically resistant
• One-handed gravity-seal design with only two parts (no clamps or locking devices)
• Graduated funnel up to 350 mL with 50 mL intervals

Advantages:

• Gravity sealing enables one-handed operation and prevents filter bypass or sample leakage
• Minimal maintenance and durability due to a two-piece design with no clamps, wheel locks, or magnets to wear out
• Autoclavable polysulfone construction provides chemical resistance suitable for cell culture and microbiological applications
• Compatibility with standard No. 8 stopper and 1-liter flasks or multi-place manifolds allows flexible laboratory workflows
