I. Basic Characteristics and Uses

1. Material Advantages

• Corrosion Resistance: PFA (Perfluoroalkoxy) resists strong acids (e.g., hydrofluoric acid, aqua regia), strong alkalis, and organic solvents.

• Temperature Range: -200°C to +260°C, suitable for high or low-temperature experimental environments.

• High Purity: Metal impurity content below 0.01ppb, ideal for precision experiments such as ICP.

2. Core Functions

• Constant Pressure Dropping: Controls drip rate by adjusting pressure to ensure experimental accuracy (e.g., quantitative reagent addition).

• Anti-Siphon and Pressure Stability: Prevents liquid backflow and reduces gas volume measurement errors.

• Liquid Separation and Extraction: Supports basic operations of separatory funnels with clear interfaces and easy drainage.

II. Technical Parameters and Specifications

• Common Capacity: 150ml (standard model), with options from 125ml to 3000ml, customizable.

• Interface Specifications: Standard joints #19, #24, #29, compatible with various flasks (e.g., PFA three-neck flasks).

• Appearance: Semi-transparent or transparent design for easy observation of liquid levels.

III. Typical Application Scenarios

1. Hydrofluoric Acid Treatment: Used with PFA distillation setups for hydrofluoric acid purification or hydrogen fluoride preparation.

2. High-Precision Experiments: Such as reactions requiring controlled drip rates in pharmaceuticals or biochemistry.

3. Corrosive Environments: Replaces glass funnels to avoid corrosion by strong acids and alkalis.
