Culture Tube, 5mL, L75mm, OD 12mm

Culture Tube, 5 mL, L 75 mm, OD 12 mm

This 5 mL culture tube is a compact, straight-walled laboratory tube designed for routine handling of small liquid volumes in medical, clinical, and research settings. With an overall length of 75 mm and an outside diameter (OD) of 12 mm, it fits common tube racks and workflows where consistent dimensions support organized processing, labeling, and storage. The tube format is well suited to general-purpose applications such as aliquoting, short-term holding of samples, reagent preparation, and small-volume culture or incubation workflows where a narrow profile is preferred.

The 12 mm OD provides a stable footprint in standard 12 mm tube racks and holders, helping keep tubes upright during filling, mixing, or transport within the laboratory. The 75 mm length supports convenient handling with gloved hands and common bench tools, while remaining compact for space-efficient organization. The 5 mL capacity is appropriate for procedures that require controlled sample volumes, reducing the need to use larger containers that may increase headspace, require more storage space, or complicate batching and rack organization.

Culture tubes are frequently used in microbiology, cell and tissue processing workflows, and general specimen handling when a simple cylindrical tube is preferred. This tube’s standardized dimensions make it practical for repeatable procedures, including serial dilutions, preparation of working solutions, and temporary containment of specimens or media during stepwise processing. It is also suitable for educational laboratories and routine diagnostic support tasks where consistent tube size helps maintain orderly workstations.

Common uses

• Aliquoting and temporary storage of small-volume clinical or laboratory samples
• Preparation and holding of reagents, buffers, stains, or diluents
• Small-volume culture, incubation, or observation workflows (method-dependent)
• Batch processing, sorting, and labeling in tube racks and carriers
• Serial dilution and mixing steps requiring uniform tube geometry

Key benefits

• Compact 75 mm length supports efficient rack storage and organized workflows
• 12 mm OD fits common 12 mm racks, holders, and many laboratory accessories
• 5 mL volume is suitable for small-volume handling and controlled reagent use
• Straightforward tube format compatible with routine bench procedures

Handling and selection notes

Select closures, sterilization status, and material compatibility based on your specific protocol and facility requirements. Verify that the tube dimensions match your racks, carriers, incubators, and any downstream instruments used in your workflow. Follow applicable laboratory safety procedures and institutional guidelines for labeling, storage conditions, and disposal of biological or chemical contents.
