5-100mm laboratory quartz stirring rod is a high-performance stirring tool designed for chemical, biological, material science and other laboratory scenarios. It is made of high-purity fused silica (SiO ₂ content ≥ 99.9%), and has excellent high temperature resistance, acid and alkali corrosion resistance and chemical inertia characteristics. The product covers diameter specifications from 5mm to 100mm and can be adapted to different capacity reaction vessels (such as test tubes, beakers, reaction kettles, etc.) to meet the mixing needs of trace to large volume samples.

Core advantages:

Corrosion resistance: Quartz material does not react with strong acids (such as aqua regia), strong bases, or organic solvents, avoiding the risk of contamination from traditional metal/plastic mixing rods.

High temperature resistance: can withstand high temperatures from -196 ℃ (liquid nitrogen) to 1200 ℃, suitable for high-temperature reactions or thermal cycling experiments.

High transparency: With a light transmittance of over 92%, it is easy to observe the real-time status of the reaction system.

Low thermal expansion coefficient: Strong thermal stability, reducing deformation or rupture caused by temperature changes.

Easy to clean: The surface is smooth and not prone to residual samples, reducing the risk of cross contamination.

Application scenarios

This product is widely used in the following laboratory scenarios to solve the limitations of traditional mixing tools:

Chemical synthesis and catalytic reactions

Problem: Metal stirring rods may catalyze side reactions, while plastic stirring rods are not resistant to high temperatures or organic solvents.

Solution: Quartz stirring rods have high chemical inertness, avoiding interference with reaction pathways, and are suitable for organic synthesis, polymerization reactions, etc.

High temperature melting and crystallization experiment

Problem: The glass mixing rod has insufficient temperature resistance and is prone to softening and deformation; Metal stirring rods may introduce impurities.

Solution: Quartz stirring rod is resistant to high temperatures and has strong thermal stability, suitable for stirring high-temperature systems such as molten salts and metal oxides.

Biological sample processing and cell culture

Problem: The release of metal ions may affect cell activity, and plastic stirring rods are prone to adsorbing proteins.

Solution: Quartz material has no biological toxicity, high surface inertness, and is suitable for precision experiments such as DNA extraction and enzyme reactions.

Stirring of corrosive media

Problem: Strong corrosive liquids such as concentrated sulfuric acid and hydrofluoric acid are prone to corrode metal/plastic stirring rods.

Solution: Quartz stirring rod is resistant to strong acids and alkalis, suitable for electrochemical corrosion, wet etching and other scenarios.

Photochemistry and Spectral Analysis Experiment

Problem: The opaque stirring rod blocks light and affects the accuracy of spectral detection.

Solution: The highly transparent quartz material allows light to pass through and is suitable for experiments such as UV visible spectrophotometers and fluorescence spectroscopy.

Frequently Asked Questions

What is the maximum temperature that quartz stirring rods can withstand?

High-purity fused quartz has a softening point of approximately 1730°C and can withstand short-term temperatures of 1100–1200°C, making it suitable for stirring operations in high-temperature melting, heat treatment, and vacuum furnaces.

Do you offer customization for non-standard sizes or special shapes?

Yes, we can customize special features such as diameter, length, bent sections, threaded connections, and ground ends based on drawings or samples. Our minimum order quantity is flexible, and we support small-batch trial production.

What is the purity of the quartz stirring rods? Will it affect experimental results?

We use high-purity fused quartz raw material with a purity of 99.99% or higher. The content of metallic impurities (Fe, Al, Na, etc.) is extremely low (<10 ppm), ensuring no contamination is introduced and guaranteeing the accuracy of experimental data.

What specific applications does the 5–100 mm diameter range cover?

The 5–10 mm fine-diameter specifications are suitable for routine dissolution stirring and flow guidance in small-volume beakers and colorimetric tubes; the 15–40 mm medium-diameter specifications are commonly used for mechanical stirring assistance in pilot-scale reactors or for homogenizing large-volume solutions; the 50–100 mm large-diameter specifications are frequently used for industrial-grade tank agitation, as supporting structural components for high-temperature melting furnace observation windows, or as load-bearing parts for special custom fixtures. We can customize any combination of diameter and length within this range based on the customer’s reaction vessel opening size and stirring intensity requirements.

How are delivery times and global logistics arranged?

Standard specifications ship within 3–5 business days, while custom parts are completed within 7–15 days. We support international express carriers such as DHL, FedEx, and UPS, covering major markets including Europe, the Americas, Japan, South Korea, and Southeast Asia.
