Corning 6220-100 Pyrex Filling Funnel 100mm Lab Funnel – 7.4oz Glass

Description

Product Overview

The Corning 6220-100 Pyrex filling funnel is engineered for laboratory professionals who demand accuracy, durability, and ease of use. Constructed from high‑quality borosilicate glass, the funnel resists thermal shock and chemical corrosion, making it suitable for a wide range of solvents, reagents, and temperature conditions. Its 100 mm (approximately 4 in) top inner diameter provides a generous opening that accommodates large‑bore tubing, pipette tips, and bulk liquid transfers without splashing. The funnel stands 120 mm tall, offering a deep reservoir that minimizes turbulence and promotes a steady, laminar flow. Weighing just 7.37 oz, the piece is lightweight enough for one‑handed operation yet robust enough to withstand repeated handling and cleaning cycles. The clear glass body allows users to visually monitor the liquid level, detect air bubbles, and verify complete transfer, reducing the risk of contamination or loss. The product dimensions of 3.94 × 3.94 × 4.72 inches ensure a compact footprint on bench tops while providing sufficient capacity for most laboratory filling tasks.

Usage

This funnel excels in a variety of laboratory environments, from academic research labs to industrial quality‑control facilities. In chemistry labs, it is used to transfer acids, bases, and organic solvents into reaction vessels, distillation apparatus, or storage containers with precision. Biologists rely on the funnel for adding culture media, buffers, and enzyme solutions to flasks, bioreactors, and sterile containers, benefiting from the glass’s inertness and the funnel’s smooth interior that prevents residue adherence. In industrial settings, the funnel serves in process engineering for feeding bulk chemicals into reactors, mixers, or filtration units, where its large opening reduces the need for auxiliary equipment. The funnel’s design also supports use with standard laboratory glassware such as beakers, Erlenmeyer flasks, and graduated cylinders, making it a versatile accessory across multiple workflows. Its compatibility with standard lab clamps and stands allows users to secure the funnel at an optimal angle, further enhancing control during pouring and reducing the chance of spills.

FAQ

What chemicals are safe to use with this funnel?

The funnel is made from borosilicate glass, which is compatible with most acids, bases, organic solvents, and aqueous solutions. It is not recommended for hydrofluoric acid or other highly aggressive fluorine‑containing compounds.

Can the funnel be autoclaved for sterilization?

Yes, the funnel can withstand standard autoclave cycles (121 °C, 15 psi) without cracking, making it suitable for sterile applications in microbiology and cell culture.

How do I clean the funnel after use?

Rinse the funnel with deionized water immediately after use, then wash with a mild detergent or laboratory glassware cleaning solution. For stubborn residues, soak in a dilute acid solution (e.g., 5 % nitric acid) followed by thorough rinsing.

Is the funnel compatible with standard lab clamps?

Yes, the funnel’s smooth, rounded neck fits most standard laboratory clamps and stands, allowing secure positioning at the desired angle for precise pouring.

What is the warranty coverage for this product?

Corning provides a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. Contact Corning customer service for claim procedures.
