Beaker, Low Form as per IS 2619 or ISO 3819 or DIN 12331

Quick Answer: A low form beaker is a short, wide glass beaker with a flat base, used for dissolving solids, mixing and warming solutions, evaporation and holding liquids for a short time at the bench. Its squat shape keeps it stable and easy to reach into with a spatula or stirring rod.

Low Form or Tall Form: Why the Shape Matters

The low form beaker, often called the Griffin form, is short in relation to its diameter. That geometry gives three practical advantages: a stable footprint that is hard to knock over, a wide mouth that takes a spatula, thermometer or glass rod without fuss, and a broad liquid surface that speeds up evaporation and cooling. The tall form version (Berzelius form) gives up some of that stability in exchange for depth, which helps when a stirrer bar and a pH electrode both need to sit below the surface, or when a boiling liquid tends to spatter.

Buying This Beaker Against a Tender Schedule

Tender schedules for school and college laboratories often describe glassware by standard number. This beaker is listed with reference to the IS 2619, ISO 3819 and DIN 12331 standard numbers in its product name, which helps match it to a line item. No conformity or testing is claimed here, so request any conformity documentation your tender needs at enquiry. The glass type is not stated either; confirm it before heating, or choose the borosilicate low form version, which names its glass.

Applications

• Dissolving a weighed solid in distilled water before transferring it to a volumetric flask to prepare a standard solution
• Precipitation reactions, such as adding barium chloride solution to a sulfate sample, with room to stir and later decant
• Evaporating a copper(II) sulfate solution until crystals begin to form on a glass rod dipped in it
• Serving as a simple water bath for warming test tubes during food tests or enzyme practicals

Specifications

Care & Handling

• Look over the rim and base of each beaker for chips or star cracks before use; a flaw that causes no trouble at room temperature can fail when heated.
• Wash with warm water, laboratory detergent and a soft brush, and avoid abrasive powders, which scratch the inner surface.
• Store beakers upright on a lined shelf or inverted on a rack rather than jammed inside one another, where a stuck pair can crack while being separated.

Why Choose LabEquip

Low form beakers are usually ordered in mixed sizes as part of a wider glassware list for a school or college, often against a tender. LabEquip lists them in its Lab Glassware category; send the sizes, quantities and any documents your tender calls for through the LabEquip contact page so the whole list can be handled together.

Frequently Asked Questions

When should I choose a low form rather than a tall form beaker?

Choose low form for general dissolving, mixing, heating and evaporation, because the wide base is stable and the large surface helps liquids evaporate and cool. Choose tall form for titrations with an immersed electrode, for boiling that tends to spatter, or when a small volume needs extra depth.

Are beaker graduations accurate enough for making standard solutions?

No. Beaker graduations, where present, are approximate and meant for rough make-up and judging fill levels. For a standard solution, dissolve the weighed solid in the beaker, transfer it quantitatively to a volumetric flask with rinsings, and make up to the mark.

Is this beaker made of borosilicate or soda-lime glass?

The product name does not say, so ask when you enquire. The difference matters: borosilicate glass has low thermal expansion and tolerates gradual heating and most acids, while soda-lime glass suits room-temperature mixing and storage but can crack under sudden temperature changes.

How should a glass beaker be heated safely?

Stand it on a wire gauze over a tripod or on a hot plate, never in a bare flame, and raise the heat gradually. Never heat it empty, and set it down on a heat-resistant mat rather than a cold or wet bench.

How do I cover a beaker while warming or holding a solution?

Rest a watch glass slightly wider than the rim on top, with the curved side facing down, so condensate collects at the centre and drips back. It keeps dust out and limits splashing, and it can be pushed slightly to one side to let vapour escape during evaporation.

How can dried residues be removed from glass beakers?

Soak in warm water with laboratory detergent and use a soft brush. Dilute hydrochloric acid lifts carbonate films and an acetone rinse removes greasy organic ones. Finish with distilled water so no spots remain after drying.
