Beakers no longer float in the water-bath! Vinyl-coated weighted support and equipped with 4 support handles for glass or plastic beakers. This device enables stable immersion of the beaker and good circulation of water around it.
To prevent breakage and tipping... The ballast rings, coated in vinyl with very good chemical resistance, support glassware in the water-baths to prevent breakage and tipping. Closed (red) or open (blue) rings.
