These 50 ml graduated beakers are made to DIN 12331 and ISO 3819 and are supplied in a pack of 6 for everyday laboratory work such as mixing, dissolving, heating and holding liquids. Each beaker has a pouring spout, an easy-to-read scale, a large labelling field for marking and uniform wall thickness. They offer high heat resistance and resist chemical attack, and the clear glass gives good visibility of the contents. Choose low form or tall form.

Frequently asked questions

Are the beaker graduations accurate enough for measuring?

No. The scale on a beaker is only a guide to the approximate volume. For an accurate volume, use a volumetric flask, pipette, burette or graduated cylinder.

What is the difference between low form and tall form?

A low form (Griffin) beaker is wider and shorter and is the usual choice for general mixing, dissolving and heating. A tall form beaker is narrower and taller and suits titrations and cases where you want less surface area.

Can I heat these beakers?

They have high heat resistance, so they can be heated on a hot plate or with a wire gauze over a flame. Avoid sudden temperature changes, do not heat an empty beaker and handle hot glass with heat-resistant gloves.

Can they be autoclaved?

Heat-resistant glassware can usually be steam sterilised, but the listing does not state the glass type, so please ask us to confirm before autoclaving.

What do DIN 12331 and ISO 3819 mean for me?

They are standards for laboratory beakers. They set the shape, size and general requirements, so beakers are consistent from batch to batch and fit standard racks and hot plates.

Which chemicals can they hold?

Laboratory glass resists most acids and organic solvents. It is attacked by hydrofluoric acid and, over time and with heat, by strong alkalis and hot concentrated phosphoric acid.

How do I clean them?

Wash with laboratory detergent and a soft brush, rinse with tap water and then distilled water. Avoid abrasive scouring powders, which scratch the glass and weaken it.

How many beakers are in a pack?

A pack contains 6 beakers of the form you select, low form or tall form.

How do I use the labelling field?

Write on the labelling field with a lab marker or pencil to note the sample name, date or initials. Most markers wipe off with solvent or detergent when the beaker is reused.

Can I get a GST invoice and a bulk or institutional quotation?

Yes. Labmart supplies colleges, hospitals, pharma companies and government laboratories across India and issues a GST invoice with every order. For bulk or institutional quantities, send us the size and quantity you need and we will share a quotation.
