1000ml PTFE Constant-Pressure Dropping Funnel

Product Overview

The 1000ml PTFE Constant Pressure Dropping Funnel is specifically engineered for precise and controlled reagent addition in highly demanding chemical environments. Unlike conventional glass funnels, this model features a pressure-equalizing side arm that maintains consistent internal pressure, ensuring a smooth and uninterrupted flow rate.

Manufactured from high-purity PTFE (Polytetrafluoroethylene), it offers exceptional chemical resistance, making it ideal for handling strong acids, bases, and ultra-trace analysis applications where contamination must be avoided.

Key Features

• Constant Pressure Design
  Equipped with a pressure-equalizing side tube to ensure stable and continuous liquid flow without interruption.
• Ultra-High Chemical Resistance
  Made from premium PTFE, resistant to HF, HNO₃, aqua regia, and aggressive organic solvents.
• Metal-Free Construction
  Eliminates risk of metal ion contamination, ideal for semiconductor and trace analysis applications.
• Precision Flow Control
  Integrated PTFE stopcock allows accurate adjustment of dropping speed.
• Wide Temperature Range
  Operational from -200°C to +250°C without deformation or degradation.
• Non-Stick Surface
  Smooth PTFE surface prevents residue adhesion and ensures easy cleaning.

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.

Applications

• Controlled reagent addition in organic synthesis
• Acid digestion and trace metal analysis
• Semiconductor and microelectronics processing
• Corrosive chemical handling systems
• Laboratory research under inert gas environments
