Laboratory beakers: for which preparation, heating and transfer applications are they used?

An essential on every lab bench, the beaker is the ultimate all-round vessel: solution preparation, heating in a water bath or on a hotplate, sampling, decanting and clean transfers thanks to the pouring spout. In borosilicate glass 3.3 or plastic (PP, PMP/TPX, PTFE/PFA), available from 5 mL to 5 L, in Griffin (low form) and Berzelius (tall form) shapes, with clear, easy-to-read graduations. Rugged and autoclavable depending on the material, it provides the right accuracy for indicative volumes (non-volumetric) and outstanding chemical compatibility for biology, chemistry and quality control workflows.

What are the different types of beakers, and how do you choose the right one?

Two main families define the category: the glass beaker and the plastic beaker. Borosilicate 3.3 glass withstands direct hotplate heating and moderate thermal shock, resists acids/bases and offers excellent dimensional stability. On the polymer side, PP is lightweight, cost-effective and autoclavable at 121°C; PMP (TPX) provides superior transparency and service temperatures up to ~150°C; PTFE/PFA excel with aggressive solvents and at high temperatures. Griffin (low-form) beakers promote evaporation and stirring; Berzelius (tall-form) beakers minimise splash losses. Reminder: a beaker is non-volumetric; its graduations are approximate. Selection criteria: medium chemistry and temperature, usable volume, readability, stackability, presence of lid/handle, ISO 3819 compliance and sterilisation requirements. See the comparison table below.

Type	Key features	Applications
Borosilicate glass	Heating, chemical inertness, durable graduations	Hotplate heating, titrations, QC
PP / PMP	Lightweight, shatterproof, autoclavable (PP), high clarity (PMP)	Routine preparations, teaching, fieldwork
PFA / PTFE	Very high chemical and thermal resistance	Strong acids, aggressive solvents, trace metal work

In which application areas are laboratory beakers used?

In life sciences, it’s used to dissolve buffers and media, rinse beads or filters, recover supernatants and take aliquots for pH measurement. In food and cosmetics quality control, it streamlines dilutions, viscosity testing, bulk density measurements and sample preparation for HPLC/GC. In pharmaceuticals, it supports weighing, blending excipients and temperature-controlled baths. In environmental work, it handles sampling, decantation, suspended solids and filtration. In chemistry, it’s the go-to companion for syntheses, precipitations and evaporation on a hotplate with a magnetic stirrer. In teaching, it offers a safe, durable and cost-effective alternative to volumetric glassware.

Frequently asked questions about laboratory beakers

Glass or plastic beaker: how to choose?
The borosilicate glass handles heat well and cleans easily. Plastic is lightweight and shatterproof; PP for autoclaving, PTFE/PFA for demanding solvents.

Can I measure a volume accurately with a beaker?
No. A beaker is non-volumetric; its graduations are indicative (±5–10% depending on model). Use a graduated cylinder or a volumetric flask for accuracy.

What temperature limits by material?
Borosilicate glass ?230 °C in use; PP 121 °C, PMP ~150 °C, PFA/PTFE up to ~260 °C. Avoid thermal shock and direct flame on plastics.

Which beakers are autoclavable?
Glass, PP and PFA/PTFE tolerate autoclaving (per the manufacturer). Protect printed markings; avoid PS, which is not autoclavable.

What safety best practices in use?
Inspect for cracks, heat gradually, use tongs, work in a fume cupboard with solvents and add a splash cover if needed.

Griffin or Berzelius form?
Griffin (low form) for stirring and rapid evaporation; Berzelius (tall form) to limit splashing and for titrations. Choose a volume 20–30% above the requirement.

What environmental impact by material?
Glass is durable and reusable; PP/PMP are locally recyclable. PTFE/PFA are very long-lived: prioritise washing and long service life.
