Normax Durham Tube DT‑6‑35

Normax Durham Tube DT-6-35

Description

The Normax Durham Tube (Model DT-6-35) is a precision glass accessory widely used in microbiology and fermentation testing to detect gas production. This small, narrow tube — with an outer diameter of 6 mm and a height of 35 mm — is designed to be placed inverted inside culture tubes or vials, where it effectively traps gas bubbles generated during microbial metabolism. Made from high-quality, transparent glass, it allows easy visual observation of gas accumulation without disturbing the culture medium.

Key Features

• Compact dimensions (6 mm × 35 mm) for easy insertion into standard culture tubes.

• Clear glass body enables direct visual monitoring of gas bubbles.

• Ideal for fermentation and gas detection studies (Durham tube method).

• “Lokal” model under Normax’s trusted glassware range.

• Supplied individually (1 piece per unit).

• Smooth edges minimize risk of breakage during placement or cleaning.

• Suitable for repeated use with proper cleaning and handling.

Specifications

• Brand: Normax

• Model: DT-6-35

• Outer Diameter: 6 mm

• Height: 35 mm

• Material: Laboratory-grade glass

• Unit: 1 piece

Applications

• Used in microbiology labs for detecting gas formation in fermentation or biochemical tests.

• Commonly applied in the Durham tube method for identifying gas-producing microorganisms.

• Suitable for academic, research, and quality control laboratories.

• Useful in microbial physiology studies involving anaerobic or facultative bacteria.

Handling & Maintenance

• Inspect for cracks or chips before each use to ensure safety and accuracy.

• Clean thoroughly using mild detergent and rinse with distilled water.

• Dry completely before placement into culture media.

• Handle gently; the narrow glass structure is fragile and requires careful manipulation.

• Store upright in a secure rack or tube holder to prevent rolling and accidental damage.

Conclusion

The Normax Durham Tube DT-6-35 is a reliable and essential laboratory tool for detecting gas formation in microbial cultures. With its precise dimensions, clear visibility, and durable glass construction, it supports consistent, accurate, and repeatable microbiological testing in both educational and professional laboratory environments.
