Separatory Funnel PTFE Valve Manufacturer,Supplier and Exporter in India

Product Code : SCL-F-10350

The Separatory Funnel PTFE Valve is a laboratory funnel used for liquid-liquid extraction, phase separation, solvent washing, and controlled drainage of immiscible liquids. It is suitable for chemistry laboratories, universities, pharmaceutical labs, testing facilities, research labs, exporters, and institutional procurement teams.

Product Description

The Separatory Funnel with PTFE Valve - Various Options 1L / 2L / 5L from Lab Glassware Manufacturer is intended for controlled separation of two immiscible liquid layers. Verified related product data confirms PTFE key stopcock, PE stopper, white enamel printing, 1000mL and 2000mL capacity options, and bore options of 2mm, 4mm, and 6mm for the PTFE key stopcock range.

A separatory funnel is used when one liquid layer must be drained from another with controlled flow. The 1L and 2L sizes are verified on related product pages; the 5L option should be confirmed before final catalogue publication. Exact glass grade, shape, graduation range, stopper size, and certificate availability should also be confirmed.

Key Features

• PTFE valve / stopcock: supports controlled drainage during liquid-liquid extraction.
• Verified 1L and 2L options: related product pages list 1000mL and 2000mL capacities.
• 5L option: included as requested, but final capacity availability should be confirmed.
• PE stopper reference: related PTFE key stopcock funnel range is supplied with PE stopper.
• Controlled bore options: related product data lists 2mm, 4mm, and 6mm bore options.
• Extraction workflow support: suitable for solvent washing, phase separation, and reaction work-up.
• Specification-dependent use: chemical compatibility, pressure risk, glass grade, and valve rating must be verified.

How to Use the Separatory Funnel with PTFE Valve

1. Select the correct funnel capacity for the liquid volume and extraction method.
2. Inspect the funnel, PTFE valve, stopper, and stem for cracks, blockage, residue, or leakage.
3. Close the PTFE valve before adding liquids.
4. Add the sample and solvent carefully, leaving headspace for shaking and venting.
5. Fit the stopper securely and invert the funnel while supporting both stopper and valve.
6. Vent frequently through the stopcock to release pressure safely.
7. Allow the layers to separate completely before draining the lower layer.
8. Clean, rinse, dry, and store the funnel after use.

Safety note: Never point the stem toward a person while venting. Do not use with pressure-generating reactions, hot liquids, incompatible solvents, or hazardous vapours unless the method and funnel compatibility are verified. Use gloves, goggles, lab coat, clamps, and a fume hood.

Care & Maintenance

• Clean the valve, bore, stem, and body immediately after use to prevent residue buildup.
• Store the PTFE valve and stopper clean, dry, and matched to the correct funnel.
• Check for leaks before every extraction, especially after solvent or cleaning exposure.
• Remove from service if the funnel is cracked, chipped, leaking, blocked, or chemically damaged.

Frequently Asked Questions

What is a Separatory Funnel PTFE Valve used for?

A Separatory Funnel PTFE Valve is used for liquid-liquid extraction and controlled separation of immiscible liquid layers.

Which capacities are available?

Related product data verifies 1000mL and 2000mL options. The requested 5L option should be confirmed before publication or ordering.

What is the advantage of a PTFE valve?

A PTFE valve provides controlled drainage and is commonly used where smooth operation and chemical-resistant flow control are required. Verify solvent compatibility for the exact method.

Does the funnel include a stopper?

Related PTFE key stopcock funnel data references a PE stopper. Confirm stopper type and size for the selected 1L, 2L, or 5L model.

Can it be used for solvent extraction?

Yes. It is intended for liquid-liquid extraction and solvent washing where the solvent, glassware, valve, and safety method are compatible.

Is the 5L separatory funnel verified?

The 5L option is included from the supplied product name, but it was not verified on the related site pages. Mark it as [confirm] before final listing approval.
