Expansion Of Liquids Apparatus
Expansion Of Liquids Apparatus (Product Code: SLE/PHY/171) is a heat demonstration set used to compare how much different liquids expand when warmed, in school and college physics labs. Five removable glass bulbs with tubes sit in a sliding frame supported in a water trough, so all the liquids are heated together and their rising levels can be compared side by side. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

What Is the Expansion of Liquids Apparatus Used For?
Fill each bulb to the same starting level with a different liquid — for example water, alcohol, glycerine or a light oil — then pour hot water into the trough. As the liquids warm together, their columns rise by different amounts, giving a clear visual comparison of how expansion depends on the liquid. It is a staple among the thermometry apparatus that schools in India use for heat and temperature topics.
The funnel tops make filling quick and reduce spills, and because the bulbs clip into the sliding frame they can be lifted out for emptying and cleaning. Handle the glass with care, let hot water cool before draining the trough, and label each bulb so students know which liquid is which.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the original equipment manufacturer of this apparatus. The company (CIN U29309HR2020PTC087597) carries out production at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). Buying from the factory means the quotation, the dispatch and any later question about replacement glassware come from one source. Read our company profile.

Frequently Asked Questions
How many tubes does the Expansion Of Liquids Apparatus have?
The Expansion Of Liquids Apparatus has five removable glass bulbs with tubes, held in a sliding frame, so up to five different liquids can be compared in a single heating run in front of the class.
How are the bulbs filled and removed?
Each bulb of the Expansion Of Liquids Apparatus has a funnel formation on top for easy filling, and the frame's sliding arrangement with clips allows the bulbs to be removed and fixed quickly for emptying, cleaning or changing liquids.
How is the Expansion Of Liquids Apparatus heated?
The Expansion Of Liquids Apparatus is supported in a water trough. Filling the trough with hot water warms all five bulbs together, so differences in liquid level come from the liquids themselves rather than from uneven heating.
Are spare glass bulbs available for the Expansion Of Liquids Apparatus?
Spare bulbs are not listed as a separate item for the Expansion Of Liquids Apparatus. Because the bulbs are removable, ask us through the contact page about replacement glass bulbs with tubes when you request your quotation.
Who manufactures the Expansion Of Liquids Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Expansion Of Liquids Apparatus, producing it at its own licensed factory in Saha, Ambala, Haryana, India, and quoting directly to institutions and trade buyers.
Can the Expansion Of Liquids Apparatus be supplied for export?
Yes, the Expansion Of Liquids Apparatus can be quoted for schools, colleges and distributors in India and international markets. Share the quantity and destination on our contact page, and ask about packing for the glass parts when you request the quotation.
