Clock Glass 45mm, 60mm, 70mm Manufacturer,Supplier and Exporter in India

Clock Glass 45mm, 60mm, 70mm (Product Code: SCI-601/106) is a shallow, curved disc of borosilicate glass, known in most laboratories as a watch glass, used to hold, weigh, cover or evaporate small quantities of material in chemistry and biology practicals. It comes in three diameters — 45 mm, 60 mm and 70 mm — for students and technicians alike, and its smooth glazed finish keeps residues easy to see. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Clock Glass (Watch Glass) Used For?

A clock glass is one of the most versatile small items on a chemistry bench. Students place a few crystals on it to weigh them on a balance, let a few drops of a salt solution evaporate on it to watch crystals appear, or lay it over a beaker to keep dust out while a solution stands. In biology it holds a small specimen, a few seeds or a drop of stain for inspection with a hand lens.

Pick a diameter slightly larger than the rim of the beaker you want to cover, and keep the smallest size for spot tests with indicators. Borosilicate glass tolerates gentle warming, but warm the glass over a water bath or on a gauze rather than in a direct flame, and let it cool before washing. Schools building up a stock of borosilicate laboratory glassware in India often order the three sizes together.

What to Specify When Ordering

• Diameter: 45 mm, 60 mm or 70 mm — list each size you need.
• Quantity per diameter, for example one per student pair or per bench.
• The beakers you plan to cover, so the right diameter can be matched.
• Product code SCI-601/106 on your enquiry.

Frequently Asked Questions

What sizes does the Clock Glass 45mm, 60mm, 70mm come in?
The Clock Glass 45mm, 60mm, 70mm (code SCI-601/106) is offered in three diameters: 45 mm, 60 mm and 70 mm. State the diameter and the quantity of each size in your enquiry, as many laboratories order a mix to suit different beakers and tasks.

Is a clock glass the same as a watch glass?
Yes. The Clock Glass 45mm, 60mm, 70mm is what most laboratories call a watch glass: a shallow, curved glass disc for holding, covering or evaporating small amounts of material. Both names describe the same kind of item.

What material and finish does the clock glass have?
The Clock Glass 45mm, 60mm, 70mm is made of borosilicate glass with a glazed, smooth finish and a clear body. Borosilicate glass copes with temperature changes better than ordinary soda-lime glass, which is why it is widely chosen for laboratory ware.

Can the clock glass be heated?
The Clock Glass 45mm, 60mm, 70mm is borosilicate, so it tolerates gentle warming when a few drops of solution are evaporated on it. For a longer life, warm it over a water bath or on a gauze rather than in a direct flame, and let it cool before washing.

Who manufactures the Clock Glass 45mm, 60mm, 70mm?
The Clock Glass 45mm, 60mm, 70mm is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory in Saha, Ambala, Haryana, India. Quotations for single sizes or mixed sets come straight from the manufacturer.
