Eppendorf Test tube rack M1289-0040

The Eppendorf Test tube rack M1289-0040 is a medium-size polypropylene bench rack designed to hold and organize up to 23 standard test tubes (18–21 mm diameter) for sample handling, transport and short-term storage.

Key Features:

• Catalog number: M1289-0040
• Tube diameter range: 18–21 mm (0.709–0.827 in)
• Capacity: 23 tubes per rack
• Rack dimensions (L×W×H): 360×80×129 mm (14.2×3.2×5.08 in)
• Hole diameter: 24.5 mm (0.965 in)
• Construction: separable two-part design; bottom part heat-resistant to 180 °C, upper part not resistant to autoclaving/120–180 °C cycles

Advantages:

• Maintains organized layout for 23 tubes of specific diameter, improving sample traceability and inventory control.
• Compact footprint (360×80 mm) conserves bench space while accommodating medium-throughput workflows.
• Separable two-part design allows the heat-resistant base to undergo high-temperature cleaning up to 180 °C without deformation.
• Oversized 24.5 mm holes enable smooth insertion/removal of tubes with minimal friction or risk of damage.
• Balanced medium format provides sufficient capacity without excessive bulk for routine laboratory protocols.
• Detachable sections facilitate rapid section removal, transfer and customized rack configuration.
