1. irudia: A single WATSON Round Bottom Test Tube. The tube is transparent, cylindrical, with a round bottom and an open top. It is designed for laboratory use.
Konfigurazioa
- Despaketatzea: Carefully remove the test tubes from their packaging. Inspect for any damage that may have occurred during transit.
- Ikuskapena: Before use, visually inspect each test tube for any defects, cracks, or contamination. Do not use damaged or contaminated tubes.
- Prestaketa: If sterilization is required for your application, ensure appropriate sterilization protocols are followed. These tubes are typically supplied clean but not sterile unless specified.
Funtzionamendu-argibideak
- Betetzea: Carefully dispense the desired liquid or sample into the test tube. Ensure the volume does not exceed the 5mL capacity to prevent spillage and allow for proper sealing.
- Zigilatzea: For secure containment, use compatible caps. This model is designed to be compatible with WATSON caps of types A, K, and T. Ensure the cap is securely fitted to prevent leakage or evaporation.
- Manipulazioa: Always handle test tubes with appropriate laboratory safety equipment, such as gloves, especially when working with hazardous materials.

- Tenperatura tartea: Polypropylene test tubes are generally suitable for a wide range of temperatures, but avoid extreme heat that could deform the plastic or compromise sample osotasuna.
Mantentzea eta biltegiratzea
- Garbiketa: These test tubes are typically single-use. If reuse is intended for specific non-critical applications, ensure thorough cleaning with appropriate laboratory detergents and rinsing with distilled water. Verify that the cleaning process does not compromise the integrity of the polypropylene.
- Esterilizazioa: If sterilization is required for reuse, methods such as autoclaving (within polypropylene's temperature limits) or chemical sterilization can be employed. Always verify the suitability of the method for polypropylene.
- Biltegiratzea: Store unused test tubes in their original packaging in a clean, dry environment, away from direct sunlight and extreme temperatures. This prevents contamination and material degradation.
- Xedapena: Dispose of used test tubes according to local regulations and laboratory waste disposal protocols, especially when containing biological or chemical hazards.
