MOQ: 20 pcs
Description
Features
High UV Transmittance, High-Temperature Resistance, Chemical Stability, Low Thermal Expansion Coefficient, Extremely low thermal expansion (5.5×10⁻⁷/°C), High Mechanical Strength
Application
Liquid-Liquid Extraction
Used to separate immiscible liquids (e.g., organic and aqueous layers) based on density differences.
01
Purification
Isolates desired compounds by partitioning between solvents.
02
Washing
Removes impurities by shaking with a solvent that dissolves unwanted substances.
03
Emulsion Breaking
Allows time for emulsions to settle before draining.
04
Chemical Reactions
Facilitates reactions requiring phase separation.
05
Key Characteristics
1. Shape – Pear-shaped or conical with a long neck for efficient separation.
2. Stopcock – A valve at the bottom controls liquid drainage.
3. Ground Glass Joint – Ensures airtight connection with stoppers or adapters.
4. Material – Typically made of borosilicate glass (heat/chemical resistant).
5. Transparency – Allows visual monitoring of layer separation.
6. Capacity Gradations – Volume markings for precise measurement.

FAQ
Q1: What's the difference between quartz separating funnel and borosilicate separating funnel?
A: Quartz offers higher temperature resistance (1100°C vs. 500°C), better UV transparency, and superior chemical durability, while borosilicate is cheaper but less robust .
Q2: Can I use this with hydrofluoric acid (HF)?
A: No, quartz reacts violently with HF. Use PTFE or fluoropolymer funnels instead .
Q3: How do I clean a quartz funnel after organic extractions?
A: Recommended methods:
- Piranha solution (3:1 H₂SO₄:H₂O₂) for organic residues .
- 10% HNO₃ soak for inorganic deposits .
- Steam cleaning at 121°C for sterilization .
Q4: Can Quartz Separating funnels replace Teflon™ separating funnels?
A: Quartz is superior for high-temperature and UV applications, while Teflon™ excels in HF resistance and flexibility.
