PALL 4959 Laboratory Manifold Elongated Standard Adapter for #8 Stopper (3/pkg)

The Pall 4959 elongated adapter is used to connect filtration funnels with extended stems to a laboratory filtration manifold. It allows the funnel to fit securely into a #8 rubber stopper, creating a tight seal for vacuum filtration procedures commonly used in microbiology and water testing laboratories.

The elongated standard adapter is designed for Pall laboratory manifolds and compatible MicroFunnel or magnetic filter funnel systems. It enables laboratories to use different funnel types with the same manifold setup, providing flexibility for multiple filtration workflows.

An elongated adapter is useful when filter funnels have longer stems that require additional reach to properly seat into the stopper or manifold connection. This design helps ensure a secure connection and consistent vacuum seal during filtration.

Laboratory manifold adapters are commonly used in microbial analysis, water quality testing, environmental monitoring, and pharmaceutical microbiology labs, where multiple samples must be filtered simultaneously using a vacuum manifold system.

The Pall 4959 elongated standard adapter is supplied in packs of three adapters, allowing laboratories to equip multiple filtration positions on a manifold system or keep spare adapters available for maintenance and replacement.
