Beaker, Tall form as per IS 2619 or ISO 3819 or DIN 12331

Quick Answer: This Tall Form Beaker (Berzelius-style, manufactured to the geometry referenced in IS 2619, ISO 3819, and DIN 12331) is a borosilicate 3.3 glass vessel with a slender profile suited to titration and heating of liquids where reduced surface-area evaporation is useful.

A tall-form beaker, sometimes called a Berzelius beaker, has a narrower diameter relative to its height compared with a standard low-form beaker. This slender shape reduces the surface area exposed to air, which helps limit evaporative loss during prolonged heating and supports splash-free mechanical stirring. It is manufactured from borosilicate 3.3 glass, giving it good resistance to thermal shock and chemical attack, and the geometry follows the tall-form beaker dimensions described in IS 2619, ISO 3819, and DIN 12331. It is fitted with a moulded spout for controlled pouring and printed graduations for approximate volume reference.

Specifications

Applications

• Titration where a stable, splash-resistant vessel is preferred
• Heating and concentrating liquids where reduced evaporative surface area is useful
• Mechanical stirring using an overhead stirrer or magnetic stirrer
• General glassware for school, college, and industrial quality-control laboratories

Care & Handling

Allow the beaker to cool gradually before rinsing with cold water to avoid thermal shock. Clean with a mild laboratory detergent and a soft brush, then rinse thoroughly with distilled water before precision work. Because tall-form beakers are narrower and less stable than low-form beakers, use a clamp stand or support when heating on an open flame. Inspect the rim and base for chips or cracks before each use, and store upright on a stable shelf away from bench edges.

What is a tall form (Berzelius) beaker used for?

A tall form beaker is commonly used for titration and heating tasks where a slender profile helps reduce evaporative loss and supports splash-free mechanical stirring, compared with a wider low-form beaker.

How is a tall form beaker different from a low form beaker?

A tall form beaker has a narrower diameter relative to its height, while a low form beaker has a wider base. The tall form reduces surface-area evaporation and suits stirring-heavy work, while the low form offers better stability on the bench.

Can this beaker be heated directly over a flame?

Yes. Because it is made from borosilicate 3.3 glass, it can withstand the thermal shock of direct heating on a hotplate or over a low flame far better than ordinary soda-lime glass. As it is narrower and taller, use a clamp stand for stability when heating.

What do IS 2619, ISO 3819, and DIN 12331 refer to?

These are reference standards commonly used for laboratory beaker dimensions and shape. IS 2619 is the Indian Standard, ISO 3819 is the corresponding international standard, and DIN 12331 is the German equivalent.
