Rapidly and repeatedly chills biological samples for use in molecular biology applications such as ethanol precipitation of DNA/RNA samples. 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; with handle. Holds twelve 0.2 to 1.5mL microcentrifuge tubes in a 3 x 4 array. 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 unit from sliding on the bench surface. Unit comes with 16 inserts. Dimensions (L x W x H): 151 x 108 x 125mm.
