Ideal for versatile applications, these polypropylene racks are designed for use on the bench, in water baths, or with ice containers. The innovative design keeps micro tubes afloat in a water bath or allows them to be pushed into crushed ice, providing precise control over sample temperature. While not recommended for autoclaving, these racks offer convenient options with detachable legs. Users can attach the legs for the rack to stand upright on the benchtop or detach them to quickly pop out samples by pushing down onto any surface, ensuring adaptability and ease of use.
