Watch Glasses Soda Manufacturer, Suppliers and Exporter in India

Jlabexport is a leading Watch Glasses Soda Manufacturer,and suppliers in India

Watch glasses soda are circular, concave laboratory glass pieces used for weighing solids, evaporating small quantities of liquid and covering beakers during laboratory work. Jlab Export is a Manufacturer & Exporter of soda-lime glass watch glasses for schools, universities, TVET institutions, research laboratories and industrial users.

The supplied category identifies standard soda-lime watch glasses, polished-edge variants, ribbed watch glasses, large-diameter clock glasses and beaker-cover configurations. Buyers should select a watch glass according to its intended procedure, required diameter, edge finish, curvature and use as an evaporation surface or beaker cover.

The category refers to sizes ranging from 50 mm student units to 200 mm industrial evaporation plates, but a complete size schedule, thickness data, packing quantities and individual variant codes are not supplied. These specifications should be confirmed through the current catalogue or formal quotation. Jlab Export states that it serves markets across Asia, Africa, Europe, North America, South America and Oceania.

How do you choose a soda-lime glass watch glass?

Choose a soda-lime glass watch glass by matching its diameter, curvature and edge design to the intended laboratory procedure. Buyers should state whether the item will be used for weighing solids, evaporating liquids, covering a beaker or supporting another specified laboratory operation.

A smaller watch glass may be required for student or routine laboratory work, while a larger format may be specified for evaporation or industrial laboratory use. The category page refers to a range from 50 mm to 200 mm, but it does not provide an active size table.

Buyers should request confirmation of the exact diameter, thickness, edge finish, pack quantity and product code before ordering. Where the watch glass must fit a particular beaker, the required beaker diameter or compatible cover size should be included in the enquiry.

What laboratory procedures use watch glasses?

Watch glasses are used on the supplied category page for weighing solids, evaporating small quantities of liquids and covering beakers to reduce contamination. The correct item should be selected according to the procedure, required surface area and compatibility with other laboratory glassware.

For weighing, buyers should confirm the required diameter and surface condition. For evaporation, the required plate size and operating conditions should be stated. For use as a beaker cover, the watch glass diameter should be matched to the vessel.

The supplied page does not provide maximum operating temperature, chemical-compatibility limits or detailed handling instructions. These details remain available on request and should not be assumed from the general category description.

Which watch glass types are listed by Jlab Export?

Jlab Export lists soda-lime glass watch glasses, polished-edge watch glasses, ribbed watch glasses, large-diameter clock glasses and beaker-cover configurations. These are category-level descriptions rather than a complete list of active SKUs.

Polished-edge watch glasses are associated with fire-polished edges. Ribbed watch glasses are described for beaker ventilation. Large-diameter clock glasses are associated with evaporation, while standard concave watch glasses are described for weighing, evaporation and beaker covering.

The live category displays one product entry, identified as product code JL-WGS-1701. It does not provide a complete variant matrix covering diameter, thickness, curvature, edge finish or packing quantity. Buyers should therefore request the current model and size list before creating a purchase order or tender schedule.

How should watch glass diameter be selected?

Watch glass diameter should be selected according to the sample quantity, required evaporation surface or beaker opening that must be covered. The supplied category refers to 50 mm student units and sizes extending to 200 mm industrial evaporation plates.

This stated range does not establish that every intermediate diameter is currently available. Buyers should list each required diameter and quantity separately in the enquiry.

Where a watch glass will be used as a beaker cover, provide the beaker capacity or outside rim diameter so compatibility can be checked. Where it will be used for evaporation, state the required diameter and intended laboratory conditions. Thickness and curvature should also be requested because these values are not supplied on the category page.

What is the difference between polished-edge and ribbed watch glasses?

A polished-edge watch glass is identified by its finished edge, while a ribbed watch glass includes a ribbed configuration associated on the category page with beaker ventilation. The appropriate type depends on how the watch glass will be handled and used.

The category describes polished-edge watch glasses as having fire-polished edges. It describes ribbed watch glasses as a configuration for beaker ventilation. However, it does not state the number or arrangement of ribs, the edge profile, diameter options or dimensional tolerances.

Buyers should request photographs, drawings or a current datasheet when a particular edge or ribbed design is mandatory. The exact offered construction should be written into the quotation rather than inferred from the category title.

Can watch glasses be used as beaker covers?

Yes, the supplied category identifies watch glasses as beaker covers used to help prevent contamination. The watch glass must be selected in a diameter that fits the intended beaker without relying only on the beakers nominal capacity.

The category also identifies ribbed watch glasses for beaker ventilation and separately refers to beaker-cover configurations. It does not provide a compatibility chart linking watch-glass diameters to specific beaker sizes.

For procurement, state the beaker capacity, rim diameter where available, required watch-glass diameter and whether a standard or ribbed cover is needed. Buyers should also confirm the number of pieces per pack and whether the offered item is supplied individually or in bulk packaging.

What should institutions include in a watch glass tender enquiry?

A watch glass tender enquiry should include the product type, diameter, quantity, edge finish, intended use, required pack size and any mandatory material or compliance documents. Each diameter should be listed as a separate BOQ line where different sizes are required.

Jlab Export states that tender buyers can request line-by-line technical quotations, datasheets, compliance or deviation statements, catalogue extracts and manufacturer-side documentation. Export packing and marking can be addressed according to the tender requirement.

The BOQ should not use only the phrase “watch glass.” It should identify whether the requirement is for a standard soda-lime watch glass, polished-edge type, ribbed type, large-diameter evaporation plate or beaker-cover configuration.
