NovaChamber^™ tube rack 

NovaChamber is a tube rack with cooling capability. Water can be frozen inside the rack, chilling the sturdy polypropylene collar which houses the sample tubes. A snap-on bottom cover is designed to seal the liquid inside. NovaChamber accommodates all commonly used tube sizes: 24 microcentrifuge tubes (0.5-2 mL), 14 tubes (12x75 mm culture tube, cryovial and a variety of blood tubes), 7 tubes (15 mL centrifuge tube) and one 50 mL tube. The cooling can be regenerated by simply placing the NovaChamber in the freezer to refreeze the liquid inside.
