SP Bel-Art Switch-Grid Test Tube Rack, Complete Set, Interchangeable Grids Included (Plastic, Adjustable Design)

Bel-Art F18745-1000 is a complete Switch-Grid™ test tube rack and 5 sets of grid inserts. The Switch-Grid™ Test Tube Racks are designed for maximum flexibility, allowing users to accommodate multiple tube sizes within a single rack. Each rack features a split-frame design, enabling quick interchangeability of grid inserts to hold different tube diameters as needed. This innovative system eliminates the need for multiple racks, saving space and cost while maintaining efficiency in laboratory workflows. Manufactured from chemical-resistant polyoxymethylene plastic, this frame is steam autoclavable at 121°C (250°F) for sterile applications.

Key Features:

• Interchangeable Grid Inserts: Each rack includes a complete set of color-coded grids designed for specific tube sizes.
• Secure Tube Placement: The three-tier structure ensures tubes remain firmly in place, minimizing movement during handling.
• Stackable & Stable: Equipped with rubber feet, these racks prevent sliding on benchtops and allow for secure stacking during storage.
• Chemical Resistance & Durability: Constructed from polyoxymethylene plastic, the rack frame and grids resist chemical exposure and can be cleaned with mild detergent, ethanol, or isopropyl alcohol. They are autoclavable at 121°C (250°F) for sterilization.
• Compact & Cost-Effective: More space-efficient and economical compared to purchasing multiple racks for different tube sizes.
