Custom Fused Quartz Glass Reagent Bottle with Tapered Standard Ground Joint

Custom Fused Quartz Glass Reagent Bottle with Tapered Standard Ground Joint

Engineered for the most demanding laboratory and industrial applications, our Custom Fused Quartz Glass Reagent Bottles offer unparalleled purity and thermal resistance. Manufactured from high-purity fused quartz, these bottles provide exceptional chemical inertness, making them ideal for storing aggressive acids, high-purity solvents, and sensitive analytical standards.

The defining feature of this bottle is the precision-ground tapered standard joint. Unlike threaded caps that can trap contaminants, the leak-proof, grease-free seal provided by the interchangeable ground joint ensures an airtight closure. This prevents sample evaporation and protects the contents from atmospheric contamination. The standardized taper allows for a perfect fit with complementary quartz glassware, such as reflux condensers or adapters, enabling seamless integration into complex reaction setups.

Fully customizable to your specific requirements, we offer flexibility in volume (from micro-scale to bulk storage), joint size (e.g., 14/20, 24/40, 29/32), and wall thickness. Whether you require a flat-bottomed bottle for bench-top stability or a round-bottom variant for heating baths, we can manufacture to your exact specifications. Choose our custom fused quartz bottles for superior durability, optical clarity, and performance in critical environments.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.

As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
