Plastic Test Tube Rack – Classic, Stackable, Interlocking & More – For Laboratory Use
Product Overview
The plastic test tube rack—also referred to as the PP test tube rack, laboratory tube organizer, or test tube holder—is one of the most fundamental and frequently used pieces of laboratory equipment. It is designed to hold multiple test tubes upright simultaneously, keeping them organized, preventing spills, and protecting fragile glassware from rolling or tipping.
Test tube racks are most commonly made of metal wires, but they can also be found as plastic, polystyrene, foam, fiberglass, and polypropylene. According to laboratory equipment standards, test tube racks come in several forms: classic rack, interlocking cube form, stackable form, test tube drying rack, slant rack, and 1-well rack.
EduSupports offers a comprehensive range of plastic test tube racks across all major functional categories to suit different laboratory needs. Our racks are manufactured from durable PP/PE plastic, offering excellent chemical resistance, lightweight portability, and long service life.
Key Features Across All Models
Durable PP/PE plastic construction – lightweight, chemical-resistant, shatter-resistant
Multiple functional configurations – classic, stackable, interlocking cube, drying, slant, and 1-well
Stable, non-slip base – prevents tipping during use
Easy to clean – smooth plastic surface resists chemical residues
Lightweight and portable – easy to handle and move around the lab

Why Choose Our Plastic Test Tube Racks?
The plastic test tube racks from EduSupports offer several distinct advantages over wooden or metal alternatives.
First, our plastic construction provides superior chemical resistance. Unlike wooden racks that may absorb chemicals or metal racks that may corrode, plastic racks resist acids, bases, and organic solvents commonly used in laboratories.
Second, the lightweight design makes them easy to handle, transport, and store. Students and laboratory staff can move racks between workstations without difficulty.
Third, our comprehensive range covers all major functional categories recognized by international laboratory standards, ensuring you can find the right rack for your specific application.
Fourth, plastic racks are cost-effective while maintaining professional quality. They offer an excellent balance of durability and affordability for educational and research budgets.
Fifth, select models are autoclavable at 121°C (250°F), making them suitable for sterile applications in biological and medical laboratories.
Functional Categories – Find Your Perfect Model
According to international laboratory standards, plastic test tube racks are classified into the following functional categories. Our product line covers all major types, with more models being added continuously.
