Polysulfone Gravi-Seal Analytical Filter Holder, 47mm, Autoclavable, Complete Unit, 1/Pk
GVS SKU: 1213865

Featuring a unique gravity-sealing design built into a durable polysulfone (PS) body, this 47mm analytical filter holder allows one-handed operation with no danger of filter bypass or sample leakage, even when using depth filters. The complete unit consists of only two parts, a funnel and a base, with no clamps, wheel locks, or magnets to manipulate or wear out. The funnel is graduated up to 350 mL in 50 mL intervals and is supplied with a No. 8 rubber stopper for mounting into standard filtration setups.

Key Construction Characteristics

• Durable, break-resistant polysulfone (PS) construction that is autoclavable and chemically resistant for cell culture and microbiological work.
• Two-piece gravity-seal design that secures the membrane and prevents sample leakage without clamps or locking devices.
• Accepts a 47mm filter disc, including depth filters and membrane filters.
• Graduated funnel marked up to 350 mL in 50 mL intervals.
• Includes a No. 8 rubber stopper that mounts in a standard 1-liter filtering flask or in three- and six-place stainless steel manifolds.

Key Performance Characteristics

• Supports individual tests in a single flask or concurrent multiple tests when used with multi-position manifolds.
• Reusable and autoclavable for repeated processing cycles.
• Broad chemical compatibility suited to aqueous sample analysis.
• Stable, solid build with no costly replacement parts.

This filter holder delivers reliable, leak-free filtration for aqueous samples while preserving sample integrity through its secure gravity-seal interface. Its simple two-part construction and autoclavable polysulfone body provide dependable, repeatable performance across routine microbiological and analytical filtration workflows.
