There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
High Heat Resistance
Quartz material exhibits outstanding heat resistance, allowing for use in various temperature environments, including high-temperature cooking or experimental conditions.
Hardness and Durability
The hardness of quartz makes it resistant to wear and tear, effectively protecting the original shape and texture of ingredients while prolonging the service life of the stirring rod.
Good Light Transmission
Quartz stirring rods typically have good light transmission, making it easier to observe ingredient changes during the stirring process.
Diverse Designs
The structure of a quartz stirring rod generally includes the rod body, head, and connecting rod. Heads are designed in various shapes, such as disks or cones, to meet different stirring needs. Connecting rods are typically equipped with adjustment knobs for easy adjustment of the stirring rod length.
Application Scenario
Chemical Experiments
In chemical experiments, quartz stirring rods are commonly used for stirring solutions and mixing reagents to ensure uniformity and accuracy throughout the experimental process. Their high-temperature resistance and corrosion resistance make them particularly suitable for experiments requiring high temperatures or strong corrosive reagents.
Biological Experiments
In biological experiments, quartz stirring rods can be used in cell culture, enzyme reactions, and other processes to provide a stable stirring environment. Their non-toxic and non-contaminating properties ensure the accuracy and reliability of experimental results.
Pharmaceutical Field
In the pharmaceutical field, quartz stirring rods are used in drug synthesis and preparation processes to ensure the purity and quality of medications. Their high purity and corrosion resistance make them indispensable tools in the pharmaceutical industry.
Quartz stirring rods offer several advantages over plastic stirring rods, including higher temperature resistance, greater chemical stability, superior structural strength, reduced risk of breakage, and a longer service life.
Quartz stirring rods are suitable for the following experimental environments:
1. High-Temperature Environments: Quartz stirring rods can be used for extended periods at temperatures up to 1100°C, with short-term use at temperatures up to 1730°C, making them ideal for high-temperature heating experiments.
2. Chemically Demanding Environments: Quartz stirring rods exhibit excellent chemical stability, with almost no reactivity with acids or bases, except for hydrofluoric acid and hot phosphoric acid. This makes them suitable for use in corrosive heating applications.
Quartz stirring rods demonstrate excellent stability in high-temperature experiments and do not deform easily. Quartz glass has a low thermal expansion coefficient, enabling it to withstand rapid temperature changes without shattering. Even when quartz glass is heated to around 1100°C and then placed in room-temperature water, it will not crack. Furthermore, quartz stirring rods possess strong heat resistance, with a short-term use temperature of up to 1300°C and a long-term use temperature of 1100°C.
