For medium-batch sample mixing, reaction preparation and sample storage needs, 25ml glass test tubes provide more ample capacity space, avoiding the tediousness of repeated dispensing with small-capacity test tubes, and effectively improving the operation efficiency of batch experiments. This product is suitable for biological experiments, chemical synthesis and sample storage scenarios with large sample volumes. It can process more samples at one time, reducing operation steps and pollution risks.
These 25ml glass test tubes are integrally formed from borosilicate glass material, with sufficient tube space, uniform wall thickness and stable structure. The tube body has high transparency, and the internal sample state and reaction process can be clearly observed. The tube mouth is finely polished and can adapt to sealing plugs of corresponding specifications with good sealing performance, suitable for short-term sample storage. With appropriate capacity and stable quality, 25ml glass test tubes have become a commonly used specification in scenarios such as biological culture and sample pretreatment.

Quality Control
We implement whole-process quality control for this product. When raw materials are put into storage, we test the purity and chemical stability of the glass material. During the production process, automated equipment monitors the tube size, wall thickness uniformity and appearance defects. Before finished products leave the factory, sampling tests are conducted on capacity error, temperature resistance and tightness. Each batch of products undergoes strict inspection to ensure stable quality. We support third-party inspection and can provide corresponding quality inspection reports.
Customization Capability
We support customization services. We can adjust the tube length, wall thickness and bottom shape according to customer requirements, and also add graduation markings and customize nozzle specifications. Customers can provide technical drawings or physical samples, and we 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.
FAQ
Q: Can these test tubes be used for centrifugation?
A: The standard round bottom model can adapt to conventional centrifuges. For high-speed centrifugation, a thickened wall version can be customized.
Q: Can they be matched with lids?
A: They can be matched with rubber stoppers, cork stoppers or plastic caps of corresponding specifications, which can be purchased together.
Q: Can they withstand high-pressure sterilization?
A: Made of borosilicate material, they can withstand high-pressure steam sterilization at 121℃ and are suitable for repeated sterilization.
