Cole Parmer Interlock Tube Rack 4 Way PP Assorted Colors Lot of 5 Racks

The Cole Parmer Interlock Tube Rack (4-Way, PP, Assorted Colors) is a versatile and compact laboratory accessory designed for organizing and holding various sizes of test tubes, centrifuge tubes, and microcentrifuge tubes. Made from durable polypropylene (PP), these racks are highly resistant to most laboratory chemicals and are autoclavable for sterilization, ensuring longevity and suitability for a wide range of applications, including use in ultra-low temperature freezers (down to -90°C). The "4-way" design means each cube-shaped rack can be rotated to accommodate different tube diameters: typically 32 x 1.5-2 mL tubes, 32 x 0.5 mL tubes, 12 x 5 or 15 mL tubes, and 4 x 50 mL tubes. Their "interlock" feature allows multiple racks to be securely connected to form larger, customized layouts, maximizing benchtop or hood space.
