In experimental scenarios with high requirements for chemical stability and thermal stability, borosilicate glass test tubes are recognized as reliable basic consumables. We have 12 years of experience in the production of glass laboratory consumables. This product is made of borosilicate 3.3 glass, with performance far exceeding ordinary soda-lime glass test tubes. It can withstand the corrosion of various reagents such as strong acids, strong bases and organic solvents, and is compatible with operations such as high-temperature sterilization and heating reactions. It is widely used in chemistry, biology, medicine and other fields.
These borosilicate glass test tubes are produced by fully automatic precision tube drawing process, with uniform tube wall thickness, high transparency, and no defects such as bubbles and scratches. The tube mouth is finely polished with smooth edges and no burrs, which not only protects the safety of operators, but also adapts to various sealing plugs. We strictly control the dimensional accuracy and appearance quality of each product to ensure that borosilicate glass test tubes can be stably adapted to various laboratory equipment such as test tube racks, centrifuges and water baths. They are highly versatile basic consumables in laboratories.

Quality Control
We have established a three-step whole-process quality control system to ensure that each product meets quality standards. In the production link, automated equipment monitors the tube wall thickness, diameter tolerance and appearance defects in real time, and unqualified products are automatically eliminated. In the processing link, manual re-inspection is carried out on nozzle polishing and size calibration. Before finished products leave the factory, sampling tests are conducted on temperature resistance, chemical resistance and dimensional accuracy. We support third-party inspection, and corresponding quality inspection reports can be provided for each batch of products.
Customization Capability
We support full-dimensional customization services. We can adjust dimensional parameters such as tube diameter, length and wall thickness according to customer requirements, and also customize graduation markings, nozzle styles and bottom shapes. Customers can provide technical drawings or physical samples, and our technical team will quickly evaluate the plan and give a quotation. The development cycle of customized samples is two weeks, and free samples can be provided for confirmation before mass production.
Packaging & Shipping
This product adopts shock-proof packaging. Conventional specifications are packed into inner boxes by piece, and the outer carton is made of thickened corrugated paper with built-in buffer foam, which effectively reduces the damage rate during transportation. For export orders, we can customize packaging specifications according to customer requirements, add moisture-proof layers, shipping marks, etc. We have sufficient inventory of conventional specifications, and the monthly production capacity of glass test tubes exceeds 3 million pieces, which can ensure the on-time delivery of large-volume orders.
