Laboratory double walled Y-shaped quartz tube

In precision material synthesis and chemical vapor deposition (CVD) processes, the structure of the reactor directly determines the success or failure of the experiment. The laboratory double walled Y-shaped quartz tube is designed specifically for multi-channel gas transport, temperature field isolation, and complex fluid mixing. Its unique Y-shaped double wall structure allows two gases to be independently preheated and uniformly mixed at the intersection, while utilizing a vacuum interlayer to achieve ultimate temperature stability. It is an ideal special customized vessel for universities, research institutes, and semiconductor materials laboratories.

Product Frequently Asked Questions (FAQ)

Q1: How to ensure that the two reaction gases do not react prematurely before entering the furnace during CVD growth of graphene?

A: Our double walled Y-shaped quartz tube adopts a separated air inlet channel, and the two gas sources flow independently in the branches of the Y-shaped tube, only coming into contact when they intersect in the high-temperature zone of the main tubeline, effectively eliminating tubeline blockage and precursor pollution problems.

Q2: Under high temperature experiments, the outer wall temperature of ordinary quartz tubes is too high, which can easily burn operators or cause aging of the sealing ring. What should be done?

A: The double wall structure of this product forms a vacuum or inert gas insulation layer, which can significantly reduce the outer wall temperature. Even if the temperature inside the tube reaches 1100 ° C, the outer wall can still be maintained within a safe touch range, ensuring experimental safety and extending the life of seals such as O-rings.

Q3: The experiment requires observing the internal powder fluidization state, but strict insulation is also needed. Can the Y-shaped tube meet this requirement?

A: Absolutely possible. We use highly transparent and high-quality gas fused quartz material, with a double wall structure that ensures thermal insulation while providing excellent visual transparency, making it easy to monitor the status changes of the materials inside the reaction chamber in real time through CCD or naked eye.

Q4: My furnace has a very special size and requires customized angles for different branch tubes. Can you do it?

A: We offer full-size customization services. From the branching angle of branch tubes (30 ° to 120 °), tube diameter (6mm to 200mm), wall thickness to total length, one-on-one design can be carried out according to your furnace size and experimental process requirements.

Typical application scenarios: from academic frontiers to industrial production

The laboratory's double walled Y-shaped quartz tube adopts an integrated blowing process and is made of high-purity quartz glass. The main body has a "Y" - shaped branch structure, with each branch being an independent hollow channel, and is designed as a double-layer sleeve structure in the key reaction section.

Typical applications include:

Photocatalytic reaction: the outer layer is filled with cooling liquid, the inner layer is filled with reaction gas, and two branches are introduced with different components respectively

CVD chemical vapor deposition: dual precursor independent transport to avoid tubeline deposition blockage

High temperature cracking experiment: sample and carrier gas separation preheating, precise control of reaction starting temperature

Biological fermentation process: one intake, one sampling, maintaining a closed and pollution-free system

Customer anonymous case study: How did they break through the bottleneck by customizing Y-shaped quartz tubes?

Case A | A Top European Photocatalytic Research Institute

-Pain point: The transmittance of imported quartz reactors decays quickly and cannot simultaneously introduce gas and liquid samples.

-Solution: Customize a double walled Y-shaped quartz tube, with the main passage passing through a liquid-phase catalyst, the side branch passing through CO ₂, and the tube wall interlayer passing through circulating cooling water.

-Result: The reaction rate was increased by 2.3 times, and there was no attenuation of light transmission after 500 hours of continuous operation.

Case B | A pilot platform for fine chemical industry

-Pain point: The stainless steel reaction kettle cannot observe the color change of the reaction, and the leaching of metal ions affects the purity of the product.

-Solution: Use a full-length transparent quartz double wall Y-shaped tube as the external circulation mirror reactor, with Y-shaped ports connected to raw materials A and B.

-Result: Real time observation of intermediate color mutation points, optimization of feeding timing, and a 76% reduction in product impurity content.

Case C | A semiconductor material supplier in North America

-Pain point: Traditional borosilicate glass tubes frequently corrode and puncture during high-temperature distillation of chlorosilane, leading to production line shutdown.

-Solution: Replace with a customized thickened quartz Y-shaped distillation tube, vacuum insulated interlayer, and Y-shaped side arm connected to the vacuum system.

-Result: The lifespan of the equipment has been extended from 3 weeks to 18 months, and the annual maintenance cost has been reduced by $110000.
