Globe Scientific TUFFBLOK Square Tube Rack (456960AST) is the compact-footprint option in the TUFFBLOK linkable system. Same four tube sizes (microcentrifuge, 12/13mm, 15/17mm, 50mL), same tool-free linking — but in a square format that reduces bench depth for tight spaces beside analyzers, inside hoods, or on narrow shelves.
Square vs. Rectangular
The rectangular model (456950) provides maximum capacity and per-section lids. This square model trades some capacity for a symmetric footprint that fits restricted bench areas. Both link with any TUFFBLOK model — standard, XL, rectangular, or square — creating mixed configurations that match your space and capacity needs.
