Product type
Test tubes are cylindrical glass or plastic containers used in laboratories for holding, mixing, or heating substances. They are typically open at the top and closed at the bottom, allowing for easy access to the contents. Test tubes are commonly made from borosilicate glass or high-quality plastics that can withstand temperature changes and chemical reactions. Their design allows for efficient mixing and observation of samples.
| Material | Borosilicate glass or polypropylene |
| Capacity | Typically ranges from 5 mL to 100 mL |
| Diameter | Common diameters include 10 mm to 25 mm |
| Length | Standard lengths range from 75 mm to 200 mm |
| Sterility | Available in sterile and non-sterile options |
| Temperature resistance | Can withstand temperatures from -80┬░C to 500┬░C depending on material |
When selecting test tubes, consider the material based on the intended use, such as glass for high-temperature applications or plastic for general use. Specify the required capacity and dimensions to ensure compatibility with your equipment. Additionally, check if you need sterile options for biological applications. Quantities may vary based on your laboratory's needs, so be prepared to discuss bulk purchasing options if necessary.
