Quarzampullen

Quarzampullen, also known as quartz ampoules or silica ampoules, are small, sealed containers typically made from fused quartz glass. These ampoules are highly valued for their exceptional purity, thermal stability, and inertness. Fused quartz, the primary material, is a form of amorphous silicon dioxide (SiO2) that exhibits very low thermal expansion, making it resistant to thermal shock. This property allows quartz ampoules to withstand rapid temperature changes without cracking.

The manufacturing process involves melting high-purity quartz sand or powder and then forming it into the desired ampoule shape. The sealing process is crucial, often achieved by flame sealing the opening to create a hermetic closure. This ensures the contents remain protected from the external environment and prevents contamination.

Due to their inertness, quartz ampoules do not react with most chemicals, making them ideal for storing sensitive substances. They are commonly used in laboratories and industries for containing and transporting volatile liquids, gases, or precious materials. Their transparency also allows for visual inspection of the contents. The high melting point of quartz, exceeding 1600 degrees Celsius, further enhances their utility in high-temperature applications, such as in certain chemical synthesis processes or as protective sheaths for temperature probes. The purity of the quartz material minimizes leaching of impurities into the stored substances, which is critical for applications in pharmaceuticals, electronics, and specialized chemical manufacturing.
