LW Scientific Hollow 100 Ball Bath Blanket 50mm. This feature allows one or two water baths to be top mounted on a bath greatly reducing the work load on the heaters and lowering energy costs. Simply immerse the appropriate lab water bath in the number of water balls specified by the manufacturer then turn the heater off and immerse the lab water bath ball in the second one from the top. The LW Scientific Bath Blanket minimizes the contact between the water bath and the lab table or bench allowing heat to transfer from one lab experiment to the next.
