The 1230 Test Culture Tube is a high-quality borosilicate glass tube equipped with a secure screw cap, engineered for long-term sample preservation and microbial cultivation. It’s available in a wide range of outer diameters (OD) and lengths to suit diverse experimental needs:

- Outer Diameter (OD) options: 12mm, 13mm, 15mm, 16mm, 18mm, 20mm, 25mm

- Length options: 75mm, 100mm, 150mm, 160mm, 180mm, 200mm

This variety ensures that researchers can select the perfect size for everything from small-scale microbial assays to large-volume cell culture experiments.

Features of the 1230 Screw Cap Culture Tube

1. Premium Borosilicate Glass Construction

Made from high-grade borosilicate glass, the 1230 culture tube offers exceptional resistance to thermal shock, chemical corrosion, and mechanical stress. It can withstand autoclaving temperatures (up to 121°C) without warping or breaking, making it ideal for sterile lab procedures.

2. Secure Screw Cap Design

The integrated screw cap creates an airtight seal, preventing sample contamination, evaporation, and leakage. This is critical for maintaining the integrity of sensitive cultures, reagents, and biological samples during storage and transport.

3. Clear Graduations (Optional)

Many variants of the 1230 test culture tube include clear volume markings, allowing for precise measurement and dispensing of liquids without the need for additional lab equipment.

4. Versatile Size Range

With OD ranging from 12mm to 25mm and lengths from 75mm to 200mm, the 1230 tube caters to a broad spectrum of applications:

- Microbial culture in liquid media

- Sample storage for clinical diagnostics

- Chemical reaction vessels

- Environmental testing and analysis

Why Choose the 1230 Test Culture Tube Over Other Lab Tubes?

Compared to standard glass test tubes or plastic alternatives, the 1230 screw cap culture tube offers distinct advantages:

- Superior Durability: Borosilicate glass outlasts plastic tubes and resists degradation from harsh chemicals, ensuring repeated use.

- Leak-Proof Storage: The screw cap design eliminates the risk of spills, a common issue with plug-sealed tubes.

- Temperature Stability: Safe for autoclaving, freezing, and heating, making it suitable for a wide range of lab protocols.

- Cost-Effective: Reusable and easy to clean, the 1230 tube reduces long-term lab supply costs compared to single-use plastic options.

 Applications of the 1230 Culture Tube

The 1230 Test Culture Tube is a workhorse in laboratories across industries:

1. Microbiology & Cell Culture

Ideal for growing bacteria, yeast, and mammalian cells in liquid or solid media. The screw cap maintains anaerobic or aerobic conditions as required for specific microbial strains.

2. Clinical & Diagnostic Labs

Used for storing patient samples, blood fractions, and diagnostic reagents, ensuring sample integrity during transit and long-term storage.

3. Chemical & Material Science

Serves as a reaction vessel for small-scale chemical synthesis, solvent storage, and material testing, thanks to its chemical resistance and thermal stability.

4. Environmental Testing

Perfect for collecting and storing water, soil, and air samples for environmental monitoring and pollution analysis.

FAQs About the 1230 Test Culture Tube

Q: Is the 1230 culture tube autoclavable?

A: Yes, the borosilicate glass construction allows for autoclaving at 121°C (15 psi) for sterilization.

Q: Can the screw cap be reused?

A: Absolutely! The screw caps are designed for repeated use, making the 1230 tube a sustainable and cost-effective lab solution.

Q: Are the tubes available with different cap colors?

A: Many suppliers offer color-coded screw caps (yellow, black, blue, etc.) for easy sample identification and organization.

Q: What is the maximum volume capacity of the 1230 tube?

A: Volume varies by size. For example, a 25mm OD x 200mm tube can hold approximately 70-80ml, while a 12mm OD x 75mm tube holds around 5-7ml.
