Thermo Scientific Powder Funnel 150 mm PP Pack of 15 Funnels

Description

Thermo Scientific™ Nalgene™ 4252-0150 Polypropylene Powder Funnel (150 mm)

The Thermo Scientific™ Nalgene™ 4252-0150 is a robust, industrial-grade powder funnel designed for the efficient transfer of dry particulate matter and viscous liquids. Manufactured from high-purity, medical-grade polypropylene, this 150 mm funnel features a specialized wide-bore, short-stem design that eliminates the “bridging” and clogging common with standard liquid funnels. Its oversized diameter and steep-walled geometry facilitate the rapid pouring of powders, granulates, and large volumes of liquid reagents. Extremely durable and chemically resistant, the 4252-0150 is built to withstand the rigors of heavy laboratory and industrial use, providing a reliable solution for bulk chemical compounding and sample preparation.

Technical Performance and Design

• Anti-Clogging Wide Stem: The oversized stem diameter is specifically engineered to allow the free flow of coarse powders and high-viscosity fluids, significantly reducing transfer time and spill risk.

• Durable Polypropylene Construction: Offers excellent chemical resistance to a broad range of acids, bases, and solvents, and is fully autoclavable for sterile applications.

• Heavy-Wall Geometry: Designed with reinforced rims and thick walls to prevent warping or cracking under the weight of bulk materials, ensuring long-term service life in high-use environments.

• Steam Autoclavable: Can be repeatedly sterilized at 121°C, making it suitable for use in microbiology, pharmaceutical production, and food science laboratories.
