Cotton Thread Roll Manufacturer,Supplier and Exporter in India

Cotton Thread Roll (Product Code: SCL-472/131) is a roll of white cotton thread used to suspend pendulum bobs, tie loads and set up pulley and string experiments in school physics labs. Physics teachers keep it on hand for the simple pendulum practical and other mechanics activities where a light, flexible thread is needed. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier to schools and colleges.

Key Details

What Is the Cotton Thread Used For?

In the simple pendulum experiment a length of thread is tied to the hook of a metal bob and clamped through a split cork, and students time the oscillations for different lengths. Cotton thread is also used to hang masses from spring balances, to pass over bench pulleys, and to tie light objects for centre-of-gravity and moment experiments.

Cut a fresh length for each set-up and check it for fraying, because a worn thread can snap and drop the bob. Measure pendulum length from the point of suspension to the centre of the bob, and tie firm knots that do not slip. White thread shows up clearly against dark stands and backgrounds, which makes length marks easy to read.

Frequently Asked Questions

What is the Cotton Thread Roll made of?
The Cotton Thread Roll (SCL-472/131) is made of cotton and is white in colour. Cotton thread is flexible and easy to knot, which suits pendulum suspensions and string experiments in school physics labs.

How long is the thread on each Cotton Thread Roll?
The thread length on each Cotton Thread Roll is not listed on this page. Contact ScienceLab through the contact page for the roll length and the quantity per pack before placing an order.

Which experiments use the Cotton Thread Roll?
The Cotton Thread Roll is used for the simple pendulum practical, hanging masses from spring balances, pulley and friction set-ups, and centre-of-gravity or moment experiments where a light string is needed.

How should the thread be used in a pendulum experiment?
When using the Cotton Thread Roll for a pendulum, cut a fresh length, tie it firmly to the bob's hook, clamp it at the suspension point and measure length to the centre of the bob. Replace frayed thread promptly.

Who supplies the Cotton Thread Roll?
The Cotton Thread Roll is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, so schools can source the thread with the bobs, split corks and stands of a complete pendulum set-up.

Can I order the Cotton Thread Roll with pendulum apparatus?
Yes, the Cotton Thread Roll can be quoted together with bobs, stands, split corks and stop clocks. List each item and quantity in one enquiry through the contact page or enquiry cart.
