Test tube laboratory rack

for centrifuge tubesfor microtubesfor storage bottles

Description
A tube rack is a laboratory accessory designed to hold and organize test tubes and sample tubes in clinical, research and pharmaceutical environments. It features a rectangular or circular frame with multiple holes or slots sized for specific tube diameters and is commonly manufactured from plastic or metal to provide stable, upright support during handling and procedures.

Use and applications
Used to hold tubes upright to prevent tipping or rolling and to facilitate organized handling during workflows such as mixing, centrifugation, incubation and specimen processing. Common in clinical diagnostics, research laboratories and production quality control.

Design and construction
Available in various sizes and configurations (rectangular or circular) with hole patterns for different tube types (PCR tubes, microcentrifuge tubes, standard test tubes). Materials typically include autoclavable plastics or corrosion‑resistant metals. Some models are stackable or modular to increase capacity and optimize benchtop organization.

Additional features

• Alphanumeric or numeric labeling for sample identification
• Color‑coding options to segregate sample groups
• Specialized inserts or holders for PCR strips and microtubes
