Lab Beakers

Lab Beakers

Shop lab beakers for mixing, heating and general sample containment in Australian laboratories. Compare PYREX and SIMAX borosilicate glass beakers, individual sizes and convenient packs for research, teaching and routine laboratory work.

Low form, tall form and Super Duty beakers

Choose short (low form) or tall form laboratory beakers to suit your bench space and procedure. PYREX Super Duty beakers have thicker glass walls for enhanced strength. The range includes capacities from 25 mL to 20 litres, with availability varying by design and brand, plus quartz beakers for specialist high-temperature applications.

Borosilicate glass is suited to many laboratory heating applications. Check the individual product specifications and manufacturer’s instructions before using a hotplate or open flame; heating limits and handling requirements depend on the glass and application.

Choose the right capacity and graduations

Graduations on beakers provide approximate liquid measurements. Check each listing for capacity, graduation markings, dimensions and pack quantity. For more accurate volume measurement, compare our glass measuring cylinders and their stated tolerances.

FAQs

What is a glass beaker, and when should I use one?

A glass beaker is an open-topped cylindrical vessel used for mixing, heating and holding liquids. It’s ideal for general lab tasks such as preparing solutions, gentle heating or temporary sample containment.

What is the difference between a low-form (short) beaker and a tall-form beaker?

Low-form (short) glass beakers are wider and better for stirring, heating and general mixing. Tall-form beakers are narrower, reducing evaporation and splashing, and are useful for reactions requiring more controlled heating.

Why choose borosilicate glass beakers instead of regular glass?

Borosilicate beaker glass offers superior thermal and chemical resistance, making it far safer for heating, cooling and handling reactive substances. Regular glass can crack or shatter under temperature change.

Can I heat a glass beaker directly on a hot plate or Bunsen burner?

Yes, borosilicate glass beakers are designed for direct heating on hot plates and can withstand open-flame exposure when used correctly. Avoid rapid temperature changes to prevent thermal shock.

What is a conical beaker, and what are its advantages for mixing or heating?

A conical beaker has sloped sides that minimise splashing and improve heat distribution. Its shape also makes swirling and mixing easier without using a stir rod.

What safety precautions should I take when using glass beakers?

Use heat-resistant gloves, avoid sudden temperature shifts, never heat cracked glass beakers and place hot beakers on heat-safe surfaces. Handle large volumes with care due to added weight.

Are the graduations on beakers accurate for measurement?

Beaker graduations are approximate only. For precise measurement, use calibrated cylinders or volumetric glassware.

How do I properly clean and maintain glass beakers to ensure longevity?

Wash with laboratory-grade detergent, rinse thoroughly and avoid abrasive scrubbing that can weaken the beaker glass. Allow heated beakers to cool gradually before washing.
