Separating Funnel

Product Code : SCL-LF-11972

The Separating Funnel 250 mL is a laboratory glassware apparatus used for separating immiscible liquids and performing liquid-liquid extraction procedures. It has a spherical clear-glass body, a tap for controlled liquid discharge, and a frosted stopper, making it suitable for chemistry laboratories, educational institutions, research facilities, and routine laboratory demonstrations.

Product Description

The Separating Funnel 250 mL allows two immiscible liquid phases to settle into separate layers according to their densities. The lower layer can then be released through the tap in a controlled manner, helping users isolate one liquid phase from another during separation or extraction procedures.

The official Science Lab Supplies listing specifies a 250 mL capacity, spherical glass body, clear appearance, tap, and frosted stopper. It also states chemical resistance and heat resistance. The product can be used alongside other laboratory glassware for chemistry teaching, sample preparation, and research workflows.

Key Features

• 250 mL capacity: Suitable for small-scale liquid separation and extraction procedures.
• Spherical glass body: Provides a clear vessel for observing the formation and position of liquid layers.
• Controlled discharge: The integrated tap allows the lower liquid phase to be released gradually.
• Frosted stopper: The verified product configuration includes a frosted stopper at the upper opening.
• Clear appearance: Helps users visually monitor liquid interfaces during separation.
• Chemical resistance: The official product listing identifies the glass funnel as chemically resistant.
• Heat resistance: Heat resistance is also specified on the official product page.

Technical Specifications

What's Included in the Kit

• One 250 mL spherical glass separating funnel.
• One tap integrated with the funnel.
• One frosted stopper.

Applications / Uses

• Separating two immiscible liquid phases.
• Performing liquid-liquid extraction procedures.
• Demonstrating density-based liquid separation in chemistry lessons.
• Supporting sample preparation and solvent extraction workflows where appropriate.
• Using with related laboratory funnels and glassware in teaching or research laboratories.

How to Use the Separating Funnel

1. Check that the tap is closed before introducing liquids.
2. Add the liquid mixture without exceeding an appropriate working level.
3. Insert the frosted stopper securely.
4. If mixing is required by the procedure, hold the stopper and tap securely and follow appropriate venting practices.
5. Place the funnel securely in a suitable support and allow the liquid phases to separate into distinct layers.
6. Remove the stopper where appropriate, open the tap carefully, and drain the lower layer into a suitable receiving vessel.
7. Close the tap at the liquid interface to prevent unwanted mixing of the collected phases.

Safety and handling note: Wear appropriate laboratory personal protective equipment. Never use cracked or damaged glassware, and follow the chemical-specific safety procedure for the liquids being handled.

Care & Maintenance

• Clean the funnel promptly using a method compatible with the chemicals previously handled.
• Rinse and dry the tap and stopper carefully to prevent residues from affecting operation.
• Store the glassware securely to reduce impact and breakage risks.
• Inspect the glass body, tap, and stopper before each use.
