Bel-Art Scienceware Poxygrid® Centrifuge Tube Racks are constructed from epoxy coated steel wire. These handy centrifuge tube racks are chemical and corrosion resistant and also steam autoclavable at 121° C (250° F) for sterile applications.
Bel-Art Scienceware No-Wire™ Multi-Size centrifuge tube racks hold three different sizes of round or conical bottom centrifuge tubes. These unique plastic lab racks accommodate 50mL centrifuge tubes, 15ml centrifuge tubes and 1.5mL microcentrifuge tubes.
Millipore's EcoStand™ centrifuge tube holder is an environmentally responsible alternative to conventional petroleum-based plastics. In addition to being made from a biodegradable corn-based resin, the EcoStand™ also features a user-friendly design for both the 50mL and 15mL centrifuge tube formats. The biodegradable and compostable EcoStand™ is made from a corn-based bioplastic resin. The stand was designed and developed in Millipore's Danvers, Massachusetts facility where the electricity we use is completely offset with green-e certified renewable energy. As a result, it reduces the use of non-renewable energy by more than 95 percent and provides a 200 percent reduction in greenhouse gases. Millipore's logo on the EcoStand™ indicates that the product is biodegradable and compostable.
The plastic resin used meets international standards ASTM D6400 and EN 13432 for compostable plastics, and ASTM D7081 and EN 17556 for biodegradable non-floating plastics in marine environments. It is engineered to fully biodegrade in diverse natural environments, including soil, home compost, industrial compost, and both fresh and salt water. Racks are compatible with standard 50mL and 15mL centrifuge tubes from numerous manufactures. Temperature Tolerance: -80 degree C to 45 degree C.
These Magic Touch™ floating racks hold 15mL conical centrifuge tubes. The expanded polymer foam construction is flexible and holds tubes securely in place during use while allowing them to slide easily in and out when needed. 15mL conical centrifuge tube racks float in water, dry ice alcohol slurries or liquid nitrogen.
Rectangular floating centrifuge tube racks fit neatly into 4-Liter Magic Touch™ Midi Lab Ice Pans and 9-Liter Magic Touch™ Midi Lab Ice Pans. Round floating centrifuge tube racks fit neatly into Magic Touch™ 2.5-Liter or 4-Liter Insulated Lab Ice Buckets.
