High purity transparent quartz culture dish is a laboratory core consumable made of high-purity silicon dioxide (SiO ₂) with a purity of 99% or higher through high-temperature melting and precision processing. Unlike ordinary glass or plastic petri dishes, it is designed for extreme environments and can withstand long-term operations at temperatures above 1100 ℃ and severe temperature fluctuations without bursting. Its excellent optical transmittance covers the ultraviolet to infrared wavelength range and has strong acid and alkali corrosion resistance (except hydrofluoric acid), making it an ideal choice to replace traditional vessels in semiconductor, photovoltaic, biomedical, and high-end scientific research experiments, ensuring the accuracy and purity of experimental data under harsh conditions.

Frequently Asked Questions (FAQ)

Q: What is the biggest difference between quartz culture dishes and ordinary high borosilicate glass culture dishes?

A: The core difference lies in the temperature resistance limit and chemical purity. Ordinary high borosilicate glass has a low softening point, is prone to deformation above 500 ℃, and contains trace metal impurities; Quartz culture dishes can work stably for a long time at 1100 ℃, with a short-term temperature resistance of up to 1450 ℃, and a SiO ₂ content of up to 99.99%. Impurities will not precipitate and interfere with experimental results in trace analysis.

Q: Can quartz culture dishes be used for UV spectroscopic analysis?

A: Absolutely possible. Quartz materials have extremely high transmittance (>80%) in the ultraviolet band (190nm-400nm), while ordinary glass hardly transmits ultraviolet light. Therefore, for experiments involving reactions or detection triggered by ultraviolet light, quartz culture dishes are necessary carriers.

Q: What are the taboos for using quartz culture dishes?

A: Although quartz is resistant to most acids and bases, it is strictly prohibited to come into contact with hydrofluoric acid (HF) and hot phosphoric acid, as these two substances can corrode the surface of quartz. In addition, although quartz has excellent thermal shock resistance, it is still recommended to handle it gently in practical operation to avoid severe mechanical impact.

Q: Do you provide non-standard customization services?

A: Yes, we have a professional CNC machining and fire machining team that supports customization of various specifications from a diameter of 25mm to 300mm. We can also customize the depth of drilling, sanding, threading, etc. according to the drawings.

Application Scenarios and Selection Guidelines

Our products are widely used in the following fields to solve application challenges in specific environments:

High temperature ashing and sintering: In ashing experiments of soil, food, and biological samples, quartz culture dishes can be directly placed in a muffle furnace and burned at 800 ℃ -1100 ℃ without residue or deformation.

Trace element analysis: In ICP-MS (Inductively Coupled Plasma Mass Spectrometry) sample pretreatment, the extremely low background value of quartz material avoids the interference of metal ions dissolved from the container wall on the detection results.

Photochemistry and UV experiments: used for photocatalytic degradation, UV curing, and other experiments. The high UV transmittance of quartz ensures that light can penetrate the wall without damage, triggering reactions.

Semiconductor and photovoltaic cleaning: In the chip or silicon wafer cleaning process, quartz culture dishes are resistant to strong acid (such as aqua regia, concentrated sulfuric acid) corrosion and will not introduce alkali metal ions such as sodium and potassium to contaminate the wafer.

Customer Application Cases

Case 1: School of Materials Science and Technology at a certain university (High Temperature Sintering Experiment)

Difficulty: During the sintering experiment of new ceramic materials in the laboratory, the originally used alumina crucible is prone to react with the sample, while ordinary glassware cannot withstand high temperatures above 1000 ℃.

Solution: Purchase our customized high-purity quartz culture dish with a diameter of 90mm.

Effect: After continuous sintering in a muffle furnace at 1100 ℃ for 50 hours, there was no crystallization or cracking on the surface of the quartz plate, and the sample was not contaminated. The experimental repeatability was significantly improved.

Case 2: A third-party environmental testing agency (for trace heavy metal detection)

Difficulty: During the detection of trace heavy metals in water quality using ICP-MS method, it was found that the background value was high, and investigation revealed that it was caused by trace metal ions precipitated from the walls of ordinary glass containers.

Solution: Fully replace with 99.99% high-purity quartz culture dishes produced by our company for sample digestion and storage.

Effect: The background value has been reduced by 50%, and the accuracy of the data has been recognized by the customer.

Case 3: A leading photovoltaic enterprise (silicon wafer cleaning process)

Challenge: The production line requires a large number of corrosion-resistant containers to hold strong acid cleaning solutions other than hydrofluoric acid. Ordinary PP plastic is temperature resistant, and glass is fragile.

Solution: Bulk purchase our company's large-sized quartz square dishes.

Effect: By utilizing the excellent acid and temperature resistance of quartz, the long-term use of the cleaning tank has been achieved, reducing the frequency of downtime and replacement, and reducing the overall cost of use by 25%.
