Cold block for 5 mL tubes
[cat. No. 1016]
Cold block made for 5 mL tubes. They will also fit 15 mL tubes, but only 4-5 mL will be inside the rack.
Pre-chill the cold block in a fridge and use it instead of an ice bucket for experiments that require low temperature.
For longer experiments, place on ice to keep your tubes uniformly cooled down.
Made from aluminum.
