What Is a Watch Glass Used For?
A watch glass is a shallow, curved glass dish. Laid over a beaker it keeps out dust and catches spray while a solution is warmed or left to stand. A few drops of solution left on it evaporate to show the crystals that form, and it holds a small amount of solid while it is weighed or examined with a hand lens. Biology students use it to hold seeds, small specimens or a stained sample, and an upturned watch glass serves as a lid for an evaporating dish.
Because the glass type is not stated, warm the watch glass gently on a water bath rather than directly in a flame, and let it cool before washing. Clean it with water and a soft brush, and store it on a cloth or in a rack so the curved surface is not scratched.
Frequently Asked Questions
What size is this watch glass?
It is 15 cm (150 mm) in diameter and is sold by number, so you order the exact quantity you need.
Is it soda glass or borosilicate glass?
The listing does not say. State which you need in your enquiry; if the watch glass will be warmed, ask for borosilicate glass to be confirmed.
Can a watch glass be heated directly in a flame?
It is better not to. Warm it on a water bath or a gently heated beaker of water, since a thin curved glass can crack if heated unevenly.
Who manufactures this watch glass?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory glassware and school science equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The watch glass is made at JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers order it factory-direct, each piece is visually inspected before it is packed, and repeat orders come from the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Turkey in the Middle East, Mongolia in East Asia, Singapore in Southeast Asia, Estonia in Northern Europe and Ivory Coast in West Africa. Tender buyers can refer to the JLab lab tenders page.
