NALGENE® DS5114 Quick Chill^TM Unit, polycarbonate; non-toxic insulating solution, with handle

Rapidly and repeatedly chills biological samples for use in molecular biology applications such as ethanol precipitation of DNA/RNA samples. The Quick Chill unit can be used repeatedly for up to 45 minutes, eliminating the inconvenience of dry ice/alcohol baths. Durable polycarbonate and pre-filled with a non-toxic insulating solution. Holds twelve 1.5 or 0.5mL microcentrifuge tubes. There’s no direct contact between the tubes and the insulating solution so labels and markings won’t come off. Break-resistant, stackable design. Rubber feet keep the Quick Chill unit from sliding on the bench surface.
