Description
Plastic floating balls form an automatic, uniform cover layer when placed in a thermostat bath. Intended exclusively for water applications, these food-grade polypropylene spheres are suitable for use up to 100 °C. With a diameter of 20 mm and supplied in a packaging unit of 1000 pieces, they create a surface blanket that should fully cover the water. Once in place, the balls help reduce heat loss, cut evaporation losses by up to 90 %, limit oxygen ingress, suppress odours and diminish light exposure on the bath contents. This accessory from manufacturer Julabo is a practical way to improve energy efficiency and bath stability in temperature-control systems without complex mechanical lids. The net weight of the pack is 1,166 kg. Suitable for laboratory and process baths where open water surfaces would otherwise drive evaporation and thermal drift, the floating balls settle into a dense monolayer and remain easy to handle when the bath is emptied or refilled during routine maintenance and sample work.

What is this article?
Hollow balls, Polypropylene, 20 mm dia., pack of 1000 pcs. is the article on this page. Luminix Health distributes Julabo for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
