Clock Glass Manufacturer,Supplier and Exporter in India

Clock Glass (Product Code: SCL301/051) is a shallow, curved borosilicate glass dish used to cover beakers, evaporate small volumes of liquid and hold solids for weighing in school and college laboratories. Its 70 mm diameter and smooth, glazed finish give a clear view of whatever sits on it, which makes it a small but constant part of borosilicate laboratory glassware in India. The Clock Glass is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Clock Glass Used For?

A clock glass earns its place on the bench through small, frequent tasks. Placed over a beaker, it keeps dust out and stops spattering while a solution is warmed. A few drops of sea water or copper sulphate solution left on it show students the solid that remains once the water evaporates, and crystals forming on the curved surface can be watched through a hand lens.

It also works as a light weighing dish for powders on a balance and as a resting place for a wet stirring rod. The glazed borosilicate surface wipes clean easily; for heating, warm the glass gently over a water bath rather than in a direct flame, and let it cool before washing.

Frequently Asked Questions

What size is the Clock Glass?
The Clock Glass (SCL301/051) has a diameter of 70 mm. That size covers small beakers and gives enough surface for evaporating a few drops of solution or weighing a small quantity of powder in school practical work.

What is the Clock Glass made of?
The Clock Glass is made of borosilicate glass with a glazed, smooth finish. Borosilicate is the glass type widely used for laboratory ware because it copes with temperature changes better than ordinary soda glass, and the smooth surface is easy to clean.

Is a clock glass the same as a watch glass?
Yes. Clock glass and watch glass are two names for the same shallow, curved glass dish. This 70 mm Clock Glass from ScienceLab serves the usual watch-glass jobs: covering beakers, evaporating small samples and holding solids for weighing.

Can the Clock Glass be heated?
The borosilicate Clock Glass can be warmed gently, ideally over a water bath or resting over a beaker of hot water. Avoid a direct flame and sudden cooling, because thin curved glass is more likely to crack under uneven heating.

Who manufactures the Clock Glass?
The Clock Glass is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools, dealers and importers receive quotations directly from this manufacturer, not through an intermediary trader.

Are other clock glass sizes available?
This listing is the 70 mm Clock Glass. ScienceLab also lists clock glasses in other diameters as separate items; state the diameters and quantities you need on the contact page so a combined quotation can be prepared.
