150ml PTFE Constant-Pressure Dropping Funnel

Product Overview

The PTFE Constant-Pressure Dropping Funnel is specifically designed for the controlled addition of highly corrosive or ultra-pure reagents. By utilizing a PFA pressure-equalization tube, this funnel allows for smooth liquid dispensing without the need to open the vessel to the atmosphere, protecting air-sensitive reactions from contamination. The opaque, pure-white PTFE construction provides superior mechanical strength and thermal stability, outperforming traditional glass funnels in safety and chemical longevity.

Bespoke Customization Services

We offer precision customization to ensure the funnel integrates perfectly with your existing laboratory manifold:

• Connection Versatility: Can be fitted with various joint sizes or specialized PFA compression fittings for secure, airtight interfaces.

• Tailored Neck Designs: Customization of the top and bottom neck lengths or diameters to suit specific reactor configurations.

• Modular Components: The PFA equalization arm can be configured in custom orientations to accommodate tight spatial constraints in fume hoods.

• High-Volume Support: While standard sizes range up to 1000ml, specific dimensional modifications can be made within this volume bracket.

Product Synergy & Workflow

Optimized for the high-purity reaction chain:

• PTFE Flasks & Reactors: The primary partner for multi-neck reactors, allowing for the safe addition of acids during exothermic reactions.

• PFA Tubing & Fittings: Used to extend the pressure arm or connect the outlet to secondary PFA fluid systems.

• PTFE Stirring Rods: Ensures immediate mixing of reagents dispensed from the funnel, maintaining a homogenous reaction environment.

Application Fields & Industries

• Trace Metal Analysis: Sample preparation and reagent dosing where glass-based silica or boron contamination must be zero.

• Semiconductor Industry: Controlled dispensing of ultra-pure etchants and specialized chemical precursors.

• Fine Chemical Synthesis: Handling of aggressive fuming acids and moisture-sensitive reagents in a fully inert environment.

• Battery Material Research: Precision addition of electrolyte components where chemical purity and system sealing are critical.
