Quartz crucibles, as indispensable high-temperature reaction vessels in laboratories, play a crucial role in material analysis, chemical experiments, and high-temperature burning due to their extremely high purity, excellent high-temperature resistance, and outstanding chemical stability. Whether dealing with extreme temperature changes or conducting trace element analysis, high-quality quartz crucibles can provide solid guarantees for the accuracy and safety of experimental data.

Requirements and Solutions

For researchers and laboratory managers, the choice of experimental vessels is directly related to the success or failure of experiments. Our customized quartz crucible can accurately solve the following core pain points:

High temperature resistance and thermal shock resistance: solve the safety hazards of softening, deformation, and even explosion of ordinary glassware in high temperature experiments above 800 ° C.

Ultra high purity and low precipitation: eliminate trace analysis errors caused by impurities (such as B, Na, Al, etc.) precipitated from the vessel during the experimental process.

Excellent chemical stability: to deal with corrosion problems in strong acids (except hydrofluoric acid) and severe chemical environments, extending the service life of vessels.

Laboratory specific applications and product advantages of quartz crucibles

Quartz crucibles are typically made of high-purity silicon dioxide (SiO2, with a purity of over 99%), and their unique physical and chemical properties make them excellent in multiple experimental fields

1. High temperature experiment and ashing treatment

When conducting organic matter ashing, precipitate burning, or muffle furnace high-temperature experiments, quartz crucibles can withstand long-term operating temperatures of over 1100 ° C, and can even reach 1450 ° C in a short period of time. Its extremely low coefficient of thermal expansion gives it excellent thermal shock resistance, and even if taken out of the high-temperature furnace and placed directly on a cold table (temperature difference>200 ° C), it is not easy to explode, greatly improving the safety and efficiency of the experiment.

2. Trace analysis and storage of ultrapure reagents

In experiments with extremely high purity requirements such as ICP-MS (Inductively Coupled Plasma Mass Spectrometry) sample pretreatment, ultra pure acid or high-purity water storage, the extremely low impurity precipitation rate of quartz crucibles can effectively avoid introducing background interference and ensure the accuracy of trace element detection results.

3. Strong chemical corrosion environment

Quartz has extremely strong acid corrosion resistance (30 times that of ceramics and 150 times that of stainless steel). In addition to hydrofluoric acid and hot phosphoric acid, it can resist the corrosion of various strong acids for a long time and is an ideal container for intense chemical reaction environments.

4. Optical and Spectral Analysis

With excellent optical transparency, quartz crucibles allow experimenters to directly observe the internal reaction process, and are also suitable for photochemical experiments that require ultraviolet light penetration to initiate reactions.

Customer application case sharing (anonymous):

The material analysis laboratory of a certain university has long faced the problems of vessel contamination and rupture during the melting experiment of a new type of ceramic material. This experiment requires the use of flux at a high temperature of 1200 ° C and has extremely high requirements for the analysis of trace elements in the material. The commonly used high borosilicate glass crucible not only frequently undergoes softening deformation, but also seriously interferes with experimental data due to the impurities precipitated.

After learning about our customized quartz crucible products, the laboratory attempted to customize a batch of high-purity, thick walled quartz crucibles. After being put into use, not only did it successfully withstand a long-term high-temperature melting environment of 1200 ° C without any deformation or explosion, but the extremely low impurity precipitation rate also improved the stability of trace element detection data by more than 90%. At present, the laboratory has used our quartz crucible as the standard consumable for its high-temperature pretreatment process.
