EISCO Filter Funnel 3.6″ Polyethylene Lab Funnel – Acid Alkali

Description

Product Overview

Introducing the EISCO 3.6 inch Polyethylene Filter Funnel, a versatile laboratory accessory designed to meet the demanding needs of scientific professionals, educators, and hobbyists alike. Constructed from high‑density polyethylene, this funnel offers exceptional resistance to corrosive acids, strong alkalis, and a wide range of organic solvents, ensuring long‑term durability even in the harshest chemical environments. The wide 3.6 inch (9.1 cm) mouth provides ample opening for rapid pouring of liquids while minimizing splashing, and the precisely engineered 3.2 inch (8.1 cm) stem with a 9 mm outer diameter fits securely into standard laboratory glassware, beakers, flasks, and graduated cylinders. Weighing only 0.63 ounces (18 grams), the funnel is lightweight enough for easy handling yet robust enough to withstand repeated use and cleaning cycles. The product dimensions of 3.6 × 3.6 × 6.3 inches (9.1 × 9.1 × 16 cm) make it compact for storage in crowded bench spaces, while the smooth interior surface prevents residue buildup and facilitates quick rinsing with water or appropriate solvents. Certified by EISCO, a trusted manufacturer in scientific glassware and plastic equipment, this funnel meets industry standards for safety and performance, and it has earned a high customer rating of 4.5 stars from over two dozen verified purchasers. Whether you are filtering precipitates, separating solid catalysts from reaction mixtures, or simply transferring liquids into narrow‑mouthed containers, this funnel delivers consistent, reliable results with minimal effort. Additional features include a chemically inert construction that does not leach contaminants into samples, a seamless junction between stem and body that eliminates crevices where particles could become trapped, and a design that complies with ASTM standards for laboratory plasticware. The funnel’s clear, bright‑colored plastic also aids visual monitoring of flow rates, making it easier to detect blockages or irregularities during filtration.

Usage

The filter funnel excels in a variety of practical settings, from advanced research laboratories conducting complex syntheses to high school chemistry classrooms introducing students to basic filtration techniques. In industrial quality‑control labs, the chemical‑resistant polyethylene construction allows the funnel to handle aggressive reagents such as hydrochloric acid, sodium hydroxide, and organic acids without degrading, making it suitable for routine sample preparation and waste management. In educational environments, the clear, bright‑colored plastic body provides visual clarity for learners, helping them observe the flow of liquids and the capture of solids during the filtration process. Home users engaged in hobbyist chemistry, small‑scale brewing, or aquarium maintenance also benefit from the funnel’s ability to separate debris from liquids, such as removing particulate matter from water changes or clarifying homemade tinctures. The ergonomic design, featuring a comfortable grip area and a short, sturdy stem, reduces strain during prolonged use, while the universal size ensures compatibility with most standard laboratory glassware, including Erlenmeyer flasks, round‑bottom flasks, and graduated cylinders. The funnel’s lightweight nature also makes it ideal for field work, where portability and ease of cleaning are essential. It can be used in conjunction with filter paper of various grades, allowing users to tailor pore size to specific applications, from coarse particle removal to fine precipitate capture. The funnel’s resistance to temperature fluctuations enables its use with both cold and warm solutions, and its non‑porous surface prevents absorption of volatile compounds, preserving sample integrity throughout the filtration process.

FAQ

What types of chemicals can the funnel safely handle?

The funnel is made from high‑density polyethylene, which is resistant to a broad spectrum of chemicals including strong acids such as hydrochloric and sulfuric acid, strong bases like sodium hydroxide, and many organic solvents. It is not recommended for use with highly oxidative agents like concentrated hydrogen peroxide or fluorinated compounds, which may degrade the material over time.

Can I use the funnel with standard filter paper?

Yes, the funnel is designed to accommodate standard laboratory filter paper of various grades. The stem diameter (9 mm) fits most filter paper holders, and the wide opening allows easy placement and removal of the paper without tearing. Users can select filter paper pore sizes based on the desired level of filtration, from coarse to fine.

How do I clean and maintain the funnel after use?

Cleaning is straightforward: rinse the funnel with warm water to remove residual liquids, then use a mild detergent if needed. For stubborn residues, a brief soak in a compatible solvent (such as ethanol) followed by thorough rinsing is effective. After cleaning, allow the funnel to air‑dry completely before storage to prevent moisture‑related issues.

Is the funnel suitable for field or portable laboratory work?

Absolutely. Its lightweight construction (0.63 oz) and compact dimensions make it easy to transport in a field kit or portable laboratory setup. The chemical‑resistant material ensures reliable performance even when used outdoors or in non‑controlled environments, and the simple design requires no additional equipment for operation.

What warranty or support does EISCO provide for this product?

EISCO offers a one‑year limited warranty covering manufacturing defects and material failures under normal use. Customers can contact the dedicated support team via email or phone for assistance with any issues, replacement parts, or technical questions. Detailed warranty terms are included with the product packaging and on the company’s website.
