Isotherm Mini Cooler –20 °C for 20 Tubes (0.5–2.0 mL)

The Isotherm Mini Cooler –20 °C for 20 Tubes is a reliable and space-saving solution for maintaining low temperatures during sample preparation. Designed for benchtop cooling of up to 20 microcentrifuge tubes (0.5 to 2.0 mL), it’s perfect for workflows involving enzymes, DNA/RNA, cell suspensions, and other heat-sensitive reagents.

Crafted from high-strength polycarbonate, the cooler is filled with a non-toxic insulating fluid that ensures uniform cold distribution—without direct contact between tubes and coolant. The lid and base feature a clear alphanumeric ID code for fast sample identification, and non-slip feet add stability during pipetting or transport.
