Sterile Disposable Test Tubes 18x140mm with Small Spout

The sterile disposable test tubes (18x140mm) are an essential tool for laboratory reagent dispensing and other scientific experiments. Each pack contains 30 high-quality, transparent test tubes, offering excellent visibility during tests. These tubes are irradiation-sterilized, ensuring they remain free from contamination, making them perfect for microbial and biochemical applications. The small spout design allows for easy liquid transfer without spills, while the flat-bottom structure enables the tubes to stand securely on lab surfaces, improving overall lab organization and efficiency.

Key Features:

• Tube Dimensions: 18mm diameter, 140mm height
• Pack Size: 30 tubes
• Sterilization: Irradiation
• Storage: Room temperature
• Durability: Wear-resistant and evenly thick
• Transparency: Offers excellent visibility for clear observations

These tubes provide sterility and durability, ensuring they remain safe for use in sensitive experiments. Designed for reliability, they support smooth workflow in laboratories focused on microbiological tests, reagent preparation, or chemical analyses.

Performance in Microbiological Testing:

In a microbial sterile test with Tryptic Soy Broth (TSB), after 14 days of incubation at 30-35°C, the test tubes showed no signs of bacterial growth or medium turbidity. This confirmed their ability to maintain a sterile environment, ideal for labs conducting sterility tests or working with sensitive cultures.

Microbiological Test Data:

• Medium: Tryptic Soy Broth (TSB)
• Temperature: 30-35°C
• Incubation Time: 14 days
• Results: No bacterial growth, clear medium

These test tubes perform exceptionally well in sterile conditions, making them ideal for microbial cultures, cell cultures, and reagent handling. Their transparent material ensures easy monitoring throughout the experimental process, while the uniform thickness guarantees consistent results.

Why These Test Tubes Are Ideal for Lab Use:

1. Sterile and Reliable: With irradiation sterilization, these tubes provide the contamination-free environment required for microbial testing.
2. Efficient Liquid Transfer: The small spout makes liquid handling easier and cleaner, preventing spills and minimizing waste.
3. Durable Design: Made to withstand lab conditions, the uniform wall thickness ensures durability and prevents breakage.
4. Versatile Application: Suitable for a variety of lab uses, including media preparation, sterile reagent handling, and sample storage.

Whether you are conducting sterility tests or preparing reagents, these tubes offer an efficient solution for laboratory supplies. Their clear design improves observation during experiments, while the flat-bottomed structure simplifies organization.
