What Is a Watch Glass?<\/h2>\n

A Watch Glass<\/strong> is a shallow, concave laboratory glassware item used in routine sample preparation and general laboratory procedures.<\/p>\n

It can provide a practical surface for holding small quantities of solid or liquid samples. It can also support weighing, drying, crystallisation and temporary covering applications.<\/p>\n

Liya Test offers four different diameters from 70 mm to 150 mm<\/strong>.<\/p>\n

70 to 150 mm Diameter Options<\/h2>\n

The product range includes \u00d870, \u00d8100, \u00d8120 and \u00d8150 mm<\/strong> models.<\/p>\n

The smaller 70 mm<\/strong> option is suitable for lower sample quantities and compact working areas.<\/p>\n

The 100 and 120 mm<\/strong> models provide intermediate working surfaces for routine laboratory procedures.<\/p>\n

For applications requiring a larger surface, the 150 mm Watch Glass<\/strong> provides the widest option in the product group.<\/p>\n

Sample Holding and Weighing<\/h2>\n

Watch Glasses can be used to temporarily hold small quantities of laboratory samples.<\/p>\n

The shallow concave form helps keep material within the central area of the glass during handling.<\/p>\n

They can also provide a simple surface for weighing suitable solid samples before further preparation or analysis.<\/p>\n

Drying and Crystallisation Applications<\/h2>\n

Watch Glasses may support suitable drying and crystallisation procedures<\/strong> where a shallow exposed surface is useful.<\/p>\n

The larger surface area allows a liquid sample to spread into a relatively thin layer.<\/p>\n

The exact procedure should always follow the applicable laboratory method and working conditions.<\/p>\n

Temporary Beaker Cover<\/h2>\n

A Watch Glass can also be placed over a suitably sized beaker as a temporary cover<\/strong>.<\/p>\n

This helps protect the contents from direct contamination while still providing a simple removable covering solution.<\/p>\n

The correct Watch Glass diameter should be selected according to the beaker opening.<\/p>\n

Choosing the Correct Size<\/h2>\n

Model selection depends mainly on the sample quantity and required working surface.<\/p>\n

Smaller models are practical for limited sample quantities. Larger diameters provide more surface area for drying, holding or covering applications.<\/p>\n

The laboratory should therefore consider both the sample volume and the vessel dimensions before selecting a model.<\/p>\n

Material Information<\/h2>\n

The current product information identifies the product as laboratory glassware but does not specify:<\/p>\n

    \n
  • glass composition<\/li>\n
  • borosilicate classification<\/li>\n
  • thickness<\/li>\n
  • thermal resistance<\/li>\n
  • edge finish<\/li>\n
  • maximum operating temperature<\/li>\n<\/ul>\n

    Therefore, these technical properties should not be added unless confirmed by the manufacturer.<\/p>\n

    Liya Test Watch Glass Range<\/h2>\n

    The available models are:<\/p>\n

    LT-G0455 \u2013 \u00d870 mm<\/strong>
    LT-G0456 \u2013 \u00d8100 mm<\/strong>
    LT-G0457 \u2013 \u00d8120 mm<\/strong>
    LT-G0458 \u2013 \u00d8150 mm<\/strong><\/p>\n

    Overall, the Watch Glass<\/strong> range provides a simple and practical solution for sample holding, weighing, drying, crystallisation and temporary vessel covering. The 70\u2013150 mm diameter options<\/strong> allow laboratories to select an appropriate size for different routine applications.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n
