Duo-Click Culture Tubes

Duo-Click culture tubes are innovative laboratory tubes designed for efficient sample handling, culturing, and storage. Featuring a unique two-position screw-cap system, these tubes provide both ventilated and airtight sealing options, making them ideal for a wide range of biological and microbiological applications. Their advanced design improves usability, reduces contamination risks, and enhances workflow efficiency in modern laboratories.

Why Choose Our Duo-Click Culture Tubes?

Dual-Position Cap for Versatile Applications

Duo-Click culture tubes feature a patented two-position screw cap that allows users to control airflow and sealing. The first “click” provides a ventilated position for aerobic culturing, while the second creates a leakproof, airtight seal for storage or anaerobic conditions.

Improved Safety & Reduced Sample Loss

Unlike traditional snap-cap tubes, Duo-Click tubes eliminate excessive force and splashing during opening and closing. This helps maintain sterility and protects both the sample and the user. 

Designed for Reliable Lab Performance

Manufactured from high-quality polypropylene or polystyrene, these tubes are durable, chemical-resistant, and suitable for centrifugation. They are available sterile and ready-to-use, supporting consistent laboratory workflows. 

Convenient & User-Friendly Design

The distinct “click” mechanism provides tactile and audible feedback, ensuring proper closure every time. Many formats include printed graduations and flat caps for easy labeling and handling.

Precision Two-Position Cap Control

The Duo-Click system allows users to control sealing by simply rotating. A quarter-turn provides a partial seal for aerobic culturing, while a half-turn fully seals the tube for airtight, anaerobic conditions. This intuitive design ensures consistent results and ease of use in laboratory workflows.

Available Sizes & Formats for Flexibility

Duo-Click round-bottom culture tubes are available in standard 5 mL and 14 mL volumes and can be manufactured in polypropylene or polystyrene. They are offered in bulk, individually wrapped, or racked formats to suit different laboratory needs.
