What Is the Carbon Paper Disc Used For?
In a ticker timer the paper tape runs under the vibrating dotter with a carbon disc between them, so every strike leaves a dot on the tape at equal time intervals. Students then measure the dot spacing to find velocity and acceleration in the motion chapter of class 9 science and in class 11 physics practicals, often with a dynamics trolley pulling the tape. Turning the disc slightly between runs brings fresh carbon under the dotter; replace it when the dots become faint or patchy, and store spare discs flat in a dry place.
Frequently Asked Questions
What does the carbon paper disc do in a ticker timer?
It marks the tape. The dotter strikes the carbon disc, which presses against the paper tape and leaves a dot for every strike, giving a timed record of the motion.
Which timer does it fit?
The listing states that it is made to fit the ticker timer. Its diameter and centre hole are not given, so quote the model of your timer, such as JLab’s Ticker Tape Timer with carbon holder, to confirm the fit.
How is it different from the Ticker Tape Carbon Disc?
The Ticker Tape Carbon Disc listing gives a 50 mm diameter with a 4 mm hole, packed in boxes of 100. This listing does not state a size or a pack, so confirm both in your enquiry.
Who manufactures the carbon paper disc?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of school physics apparatus and consumables in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These discs come from JLab’s own works, not from a trader, so schools, colleges, dealers and importers can order timers and their consumables from one manufacturer, with each item visually inspected before dispatch. JLab exports worldwide and ships to buyers in every region — for example Nepal in South Asia, Guyana in South America, Estonia in Northern Europe, Iraq in the Middle East and Tunisia in North Africa. Tender information is on the JLab lab tenders page.
