Starter Ice-Free Cooler Holder with Cooling Core

No mess, no maintenance|Keep samples cold without melting ice contamination, inconvenient batteries, or power cord clutter Cooling core maintains sample temperatures at 0.5?C to 4?C for at least four hours Compatible with all Corning CoolSink? and CoolRack? sample modules (order separately)|These benchtop coolers eliminate possible contamination from ice, maintenance costs associated with battery replacement, and messy cords. Simply freeze the cooling core in a -20?C freezer for 12 or more hours, then remove and wait for core to reach 1?C before placing in holder. Once the core is installed, add your CoolSink or CoolRack module and load your samples. Samples quickly equilibrate to the core temperature and remain chilled for 4 to 16 hours. Choose the Starter system with a low profile and smaller footprint (ideal for use in hoods) for shorter-term cooling, up to four hours.
