Quick, easily reproducible cooling of biological samples for molecular biology, e.g. for ethanol precipitation with DNA/RNA samples. Stable polycarbonate with a non-toxic insulation liquid. No direct contact between the reaction containers and the isolation liquid so that markings and labels are retained. Unbreakable, stackable, space saving and non-slip. For 12 reaction vessels 0.2/0.5/1.5mL.

Cooling Time:
for -20°C (Isopropanol) or 0°C (Water), container at ambient temperature
