Polypropylene Water Bath Spheres
Polypropylene Water Bath Spheres (Product Code: SLE/WB/13) are hollow plastic balls used to form a floating insulating blanket on the surface of a heated laboratory water bath. Spread across the water, they reduce thermal losses and save energy while still letting tubes and flasks be pushed down through the layer. These water bath accessories for labs in India are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Are Water Bath Spheres Used For?
Most heat escapes from an open water bath through its surface. A layer of hollow polypropylene spheres floating on the water acts like a loose, self-adjusting cover: the trapped air in each sphere insulates, so the heater cycles less often and the water reaches and holds its set temperature using less energy. A floating layer also shields the water from the room air, which in general helps to cut evaporation and the need for top-ups during long runs.
Unlike a rigid lid, the spheres simply part when you lower a test tube rack, flask or bottle into the bath and close up again around it, so they suit baths of any shape and baths that are loaded often. Add enough spheres to cover the surface completely, lift them out with a sieve or net when you drain the bath, and wash them whenever you clean the bath. They are a simple way to improve the efficiency of an existing water bath in India’s teaching and testing labs.
What to Specify When Ordering

Frequently Asked Questions
What are Polypropylene Water Bath Spheres made of?
Polypropylene Water Bath Spheres are hollow spheres made of polypropylene. Being hollow, they float on the bath water and form a blanket over the surface that reduces thermal losses, which saves energy while the bath is running.
How many Polypropylene Water Bath Spheres do I need?
You need enough Polypropylene Water Bath Spheres to cover the whole water surface. The sphere size and pack quantity are not given in the listing, so send us the internal length and width of your bath and we will quote a suitable quantity.
Can I still put tubes into a bath covered with Polypropylene Water Bath Spheres?
Yes. Polypropylene Water Bath Spheres move aside when you lower tubes, racks or flasks into the water and close around them again, so the blanket stays in place while you load and unload samples.
Should I use a lid or Polypropylene Water Bath Spheres?
Polypropylene Water Bath Spheres suit any bath shape and allow constant access; a rigid lid gives a full cover and view but must be opened to reach samples. For small 2 or 4 litre unstirred baths, the hinged gable lid is an alternative.
Who supplies Polypropylene Water Bath Spheres?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India supplies Polypropylene Water Bath Spheres on their own or together with water baths, racks and lids for laboratories in India and international markets.
