Fused silica glass plate, with its excellent physical and chemical properties, has become an indispensable core material in the manufacturing of modern high-end laboratory equipment. From precise optical experiments to rigorous high-temperature reactions, it provides the most reliable guarantee for the stability of precision experiments and the accuracy of data.

FAQ: How can fused silica glass solve your laboratory problems?

Q: My experiment requires extremely high UV transmittance, but ordinary glass absorbs most of the UV light, resulting in biased experimental results. What should I do?

Answer: Our fused silica glass plate has a very high transmittance in the ultraviolet, visible and near-infrared spectral range. Especially in the ultraviolet band (such as 185nm-350nm), the transmittance is far higher than that of ordinary optical glass, which can ensure that your photochemical, spectral analysis and other experiments obtain the most accurate spectral data.

Q: During high-temperature reaction experiments, ordinary glassware often explodes due to thermal shock, which is very dangerous and affects the experimental process. Is there a safer option?

Answer: The extremely low coefficient of thermal expansion of fused silica glass plate makes it have excellent thermal shock resistance. It can withstand drastic temperature changes (such as direct input of cold water from 1000 ° C), making it an ideal window or carrier for high-temperature decomposition, combustion experiments, and tubular furnaces, greatly improving the safety and continuity of experiments.

Q: Our laboratory often deals with strong acids and bases, and ordinary materials are prone to corrosion, which affects the purity of the samples. How to avoid it?

Answer: Except for hydrofluoric acid and hot phosphoric acid, fused silica glass plate hardly reacts with other acids, alkalis and salts. It is the best choice for ultrapure water analysis and strong corrosive chemical reaction containers, which can fundamentally eliminate the precipitation of impurities and ensure the cleanness of the experimental environment and the authenticity of the results.

Fused silica glass plate: core component for precision experiment

In the pursuit of ultimate precision and reliability in the laboratory field, every component of the equipment is crucial. Fused silica glass plate, with its unique performance advantages, has become the preferred material for many high-end laboratory equipment.

Core Product Advantage: Why does your device need it?

Extreme optical purity: Provides a wide spectral transmission range from deep ultraviolet (UV) to near-infrared (IR) (transmittance>90%), with extremely low impurity content (total amount of metal impurities<20ppm), ensuring lossless and interference free transmission of optical signals.

Excellent thermal stability: softening temperature up to 1700 ° C, can be used for a long time at 1100 ° C. Its extremely low coefficient of thermal expansion (5.5 x 10 ^ -7/° C) allows it to easily handle cold and hot cycles without deformation or cracking.

Excellent chemical inertness: resistant to almost all corrosive chemical reagents (except HF and hot H3PO4), ensuring stable performance in harsh chemical environments without contaminating experimental samples.

High mechanical strength and electrical insulation: The material is hard, the surface is smooth, easy to clean, and has excellent electrical insulation performance and dielectric constant, suitable for experiments in high voltage or high-frequency electric field environments.

The laboratory pain points we have addressed

Addressing the issue of light decay: By using our high-purity quartz plates in laser equipment and photochemical reactors, we can significantly reduce energy loss in laser windows or lenses and extend equipment lifespan.

Eliminating thermal stress hazards: In rapid heat treatment (RTP) equipment and CVD deposition systems, our quartz plate serves as the carrier substrate, ensuring a uniform temperature field and avoiding silicon wafer warping or cracking caused by thermal stress.

Preventing cross contamination: In trace analysis and microchip detection, our high-purity quartz slides or reaction tanks can provide a completely inert reaction interface, ensuring the accuracy of detection results.

Customer application case sharing

Case 1: A well-known spectral analyzer manufacturer in Germany

Requirement: We need an optical window material for deep ultraviolet Raman spectroscopy, which requires a transmittance of>85% at a wavelength of 244nm and an extremely low birefringence to ensure that the polarization states of excitation and scattering light are not affected.

Our solution: We have provided optical grade quartz glass plate with synthetic fused silica as raw material and special annealing process, and carried out precision polishing and interferometer detection to ensure its surface flatness reaches λ/10, and the stress birefringence is less than 5nm/cm.

Final effect: The customer integrated our quartz window into their new generation spectrometer, successfully improving the light signal collection efficiency in the deep ultraviolet band by 15%, significantly enhancing the instrument's ability to detect weak signals, and achieving great success in the market.

Case 2: Materials Laboratory at a Top University in North America

Requirement: The laboratory needs to build a new type of chemical vapor deposition (CVD) equipment for growing two-dimensional materials. A fused silica bearing plate with oversize (400mm x 400mm) and uniform thickness (± 0.1mm) is required, and it is required to be flat and not warped at 1200 ° C high temperature.

Our solution: We have closely communicated with laboratory engineers and customized high-purity fused silica plates for them. We have optimized the cutting and grinding processes and adopted a special support method for heat treatment at high temperatures to eliminate internal stress and ensure its geometric stability in high-temperature environments.

Final effect: The carrier plate is perfectly adapted to the new CVD equipment. During months of repeated high-temperature experiments (cycling from room temperature to 1200 ° C), the quartz plate remained flat, ensuring uniform distribution of airflow and temperature fields, which played a key role in the successful growth of high-quality molybdenum disulfide thin films in the laboratory.

We understand the uniqueness of each experiment, so our quartz glass plate solution should also be unique. No matter how specific or complex your needs are, we can provide you with full support from design to finished product.
