Test Tubes
Laboratory test tubes and culture tubes are used for sample collection, storage, and general laboratory procedures in clinical, research, and industrial environments. This category includes 13 x 75 mm and 16 x 100 mm test tubes in both polystyrene and polypropylene, as well as 17 x 100 mm (14 mL) culture tubes for microbiology and media applications. Designed for compatibility with standard laboratory racks and equipment, these tubes are also compatible with flange caps for secure sealing. Reliable and versatile, test tubes support a wide range of sample handling and processing workflows.
Selecting Test Tubes for Your Workflow
Choosing the right test tube depends on application, material requirements, and compatibility with your laboratory setup.
Tube sizes and formats:
13 x 75 mm and 16 x 100 mm test tubes are commonly used for general laboratory and clinical applications, while 17 x 100 mm (14 mL) culture tubes are ideal for microbiology and media preparation.
Material – Polystyrene (PS):
Polystyrene test tubes offer excellent optical clarity, making them ideal for visual inspection, colorimetric testing, and general lab use.
Material – Polypropylene (PP):
Polypropylene test tubes provide greater chemical resistance and temperature tolerance, making them suitable for more demanding applications.
Flange cap compatibility:
These tubes are designed to work with 12 mm, 13 mm, and 16 mm flange caps, ensuring a secure seal for storage and transport.
Clarity and visibility:
Clear construction allows for easy monitoring of samples and accurate measurement.
Sterility:
Sterile options are recommended for clinical, microbiology, and sensitive laboratory applications.
Workflow compatibility:
Designed to fit standard racks, holders, and laboratory equipment for seamless integration.
For most laboratory workflows, maintaining a mix of polystyrene tubes for general use and polypropylene tubes for more demanding applications provides flexibility and reliability. Culture tubes are essential for microbiology and sample growth applications.
