Three necked quartz flask

What does it solve for you?

Q: I need an experimental container that can perform multiple operations simultaneously and withstand high temperatures. What are the recommendations?  

Answer: The three necked quartz flask provides three standard interfaces and supports simultaneous connection of thermometers, stirrers, drip funnels, and other devices to achieve synchronous multi-step reactions, significantly improving experimental efficiency.

Q: My experiment involves strong acid, high temperature, or precision synthesis, with extremely high requirements for material purity and stability. How should I choose?  

Answer: High purity quartz material (SiO ₂ ≥ 99.99%) has excellent corrosion resistance, low thermal expansion coefficient, and excellent thermal stability, and can withstand extreme environments from -100 ℃ to 1250 ℃, ensuring accurate and reliable experimental data.

Q: We have different production scales and need to flexibly customize flasks with different specifications and interfaces. Do you have a professional supplier?  

Answer: We support full-size customization (50ml to 50L), with adjustable interface types (grinding specifications, angles), bottle thickness, and special functional designs (such as scale lines and reinforcement ribs), fully matching your process requirements.

Product Overview

The three necked quartz flask is a core container in the fields of chemical synthesis, material preparation, drug research and development, and high-end analysis. Its unique three neck design allows users to integrate multiple operations in the same closed system, reducing transfer steps and pollution risks, making it particularly suitable for reaction processes that require precise temperature control, continuous stirring, or inert atmosphere protection.

Key features and advantages

-Excellent material performance

Using the arc method to melt high-purity quartz sand, it has:

-High thermal stability: softening point up to 1730 ℃, long-term use temperature up to 1100 ℃.

-Corrosion resistance: resistant to all common acids and organic solvents except hydrofluoric acid.

-Low precipitation risk: Extremely low metal ion precipitation (total impurity content<50ppm), ensuring sample purity.

-Transparent and Visible: High transparency in the ultraviolet to infrared wavelength range, making it easy to observe the reaction process.

-Precise structural design

-Standard grinding interface (ISO/KF or customized specifications): ensures airtightness and reduces the risk of leakage.

-Uniform wall thickness (± 0.2mm tolerance): Avoid rupture caused by local stress.

-Smooth transition design with round bottom: Optimize fluid dynamics and enhance stirring efficiency.
