Bucket & Cylinder
Bucket & Cylinder (Product Code: SLE/PHY/140) is a brass apparatus used to verify Archimedes' principle, showing that the upthrust on a submerged cylinder equals the weight of liquid it displaces, in school and college physics labs. The cylinder hooks beneath the bucket, and the unit, listed at 60 mm with an overall size of 160 mm, suits both teacher demonstrations and individual student work. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Bucket and Cylinder Apparatus Used For?
Students record three readings. First, the bucket hangs from a spring balance by its top loop with the cylinder on the bottom hook, in air. Second, the cylinder alone is lowered fully into water and the lower reading is noted. Third, the empty bucket is filled with water while the cylinder stays submerged, and the balance returns to the first reading.
Because the solid cylinder and the inside of the bucket hold the same volume in this type of apparatus, the water added to the bucket weighs exactly as much as the upthrust lost in step two. It is a low-cost addition to physics lab instruments in India for the fluids topic. Wipe the brass dry after each class and hang the parts by their hooks so the loop and hooks keep their shape.
What to Specify When Ordering
- The product code SLE/PHY/140, since other bucket and cylinder sizes are also listed on the site.
- How many sets you need: one for a teacher demonstration or one per student group for individual use.
- Whether spring balances or measuring cylinders should be quoted with the sets.

Frequently Asked Questions
How does the Bucket & Cylinder verify Archimedes' principle?
With the Bucket & Cylinder hanging from a spring balance, the reading drops when the cylinder is submerged in water. Filling the bucket with water restores the reading, showing that the upthrust equals the weight of the water the cylinder displaced.
What size is the Bucket & Cylinder (SLE/PHY/140)?
The Bucket & Cylinder (SLE/PHY/140) is listed as 60 mm with an overall size of 160 mm. The listing does not say which part the 60 mm refers to, so ask us through the contact page if you need exact bucket or cylinder dimensions.
Can students use the Bucket & Cylinder individually?
Yes, the Bucket & Cylinder is suitable for class demonstration or individual use. Many labs order one set for the teacher and further sets so that small groups can take their own three readings and compare results.
What else is needed with the Bucket & Cylinder?
To use the Bucket & Cylinder you also need a spring balance to hang it from, a vessel of water deep enough to cover the cylinder, and a stand or hand to hold the balance. These are ordered separately if required.
Who manufactures the Bucket & Cylinder?
The Bucket & Cylinder is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders for extra sets come directly from the manufacturer.
What should a Bucket & Cylinder quotation request include?
A Bucket & Cylinder quotation request should mention the product code SLE/PHY/140, the number of sets, any spring balances or measuring cylinders you want added, and the delivery address in India or overseas.
