Product Guide

Powder funnel

A laboratory funnel or separation vessel for its intended liquid, powder or filtration duty. Outlet geometry, stopcock or filter connection, capacity and material compatibility determine the configuration; vacuum operation requires appropriately rated components.

Practical purchasing guidance for universities, research laboratories, industry and institutional buyers.

Applications and workflows

Typical workflows help you define the application and compare suitable product configurations.

  • Sample separation, concentration and liquid handling
  • Filtration, clarification and analytical sample preparation
  • Sample preparation, transfer and laboratory storage

Technical selection criteria

Include these parameters in your inquiry to align laboratory users, technical teams and purchasing.

  • Dimensions, volume, tolerances and connection geometry
  • Material grade and chemical or thermal compatibility
  • Pressure or vacuum range and safe material compatibility
  • Wetted materials, cleaning and chemical resistance
Variants and compatibility

Material, dimensions, closure, sterility and instrument fit distinguish variants. A nominal capacity or product name alone is not sufficient for compatibility.

Documentation and delivery

Request dimensions, material specification and instrument compatibility. Sterility, food contact, medical suitability or nuclease-free status must be explicitly documented when needed; they cannot be inferred from the generic name. Agree protective packaging and the supplied unit count.

Confirm the required documents, packaging and delivery conditions for the selected item and destination.
