Water Bath Balls

Designed to cover open water baths so that a fixed cover is not required.

Ideal for rotary evaporators and all other heating water baths, simply pop these into the bath where they align to form an even layer covering the surface of the water completely.


The novel design of these hollow balls prevents heat loss and evaporation (up to 90%), reduce oxygen input, reduce odours and levels of algae growth in the water.

Made of Polypropylene, these may be cleaned.
