Bel-Art Lab Funnel Polypropylene 60° Stem

Description

Product Overview

The Bel-Art Lab Funnel is engineered for reliable performance in demanding laboratory environments. Constructed from high‑grade polypropylene, the funnel offers chemical resistance and durability while maintaining a lightweight profile. Its 60 Degree cone angle and long stem promote rapid, laminar flow, and the smooth interior walls minimize sample retention. External ribs are strategically placed to prevent air lock, ensuring uninterrupted filtration. The funnel accommodates 110 mm to 125 mm filter paper, making it versatile for a range of protocols.

Usage

Designed for scientific research, quality control, and educational labs, this funnel excels in sample preparation, liquid transfer, and filtration tasks. Whether you are processing cell culture media, extracting compounds, or clarifying solutions, the funnel’s robust design withstands repeated autoclaving at 121 °C (250 °F). Its compact 8 × 8 × 3 inch dimensions fit comfortably on benchtops and within standard fume hoods.

FAQ

Can the funnel be autoclaved?

Yes, the funnel is steam sterilizable at 121 °C (250 °F) and can withstand repeated autoclave cycles without deformation.

What filter paper sizes are compatible?

The funnel accommodates filter papers with diameters ranging from 110 mm to 125 mm, covering most standard laboratory filters.

Is the material chemically resistant?

Polypropylene offers excellent resistance to acids, bases, and organic solvents commonly used in laboratory settings.

How do the external ribs improve performance?

The ribs break surface tension and prevent air pockets from forming, ensuring a steady flow and reducing the risk of filtration blockage.

What is the best way to clean the funnel after use?

Rinse with distilled water, then autoclave or soak in a mild detergent solution. The smooth interior walls prevent residue buildup.
