Introduction
Few items are as familiar on a New Zealand bench as the beaker. Its straight sides, flat base and small pouring lip turn up everywhere, from university teaching labs and Crown Research Institutes to dairy and primary industry testing, water quality work and school science rooms.
Most people looking up beakers want one of three things: to buy the right one, to understand how the types differ, or to find a supplier they can rely on. LabFriend stocks a full range of laboratory glassware, including borosilicate glass, plastic, low form and graduated beakers from established manufacturers.
Below we walk through what a beaker actually is, the jobs it handles, the shapes and materials on offer, and a simple way to match one to your work.
What is a beaker?
Put simply, a beaker is a cylindrical vessel for holding, mixing, heating and pouring liquids. The design is deliberately plain: a flat base for stability, a wide mouth for access, printed marks for a rough sense of volume, and a lip so you can pour without spills.
You will come across beakers in three main materials, each suited to different conditions:
- Borosilicate glass, such as DURAN or Pyrex, which shrugs off heat and stays chemically inert
- Plastic, usually polypropylene or PMP, which is light and will not shatter if dropped
- Quartz or PTFE, reserved for demanding work at extreme temperatures
Everyday uses on the bench
Because the mouth is wide and the walls are straight, a beaker adapts to almost any routine task. Common jobs include:
- Combining reagents and preparing solutions
- Judging a volume quickly by eye
- Warming liquids on a hotplate or Bunsen burner
- Prepping samples for dairy, food or water testing
- Catching filtrate as it comes through a filter
- Decanting liquids from one vessel to another
approximate volume
Trust the meniscus, not the mark. A beaker's graduations are only an estimate. When the exact figure matters, reach for a volumetric flask or a measuring cylinder.

How to choose the right beaker
Run through these four points before adding one to your cart:
- 1Capacity. Beakers run from 25 mL up to 2,000 mL, so match the size to your working volume.
- 2Material. Reach for borosilicate glass when heat is involved, and plastic for everyday handling.
- 3Graduations. Read them as a guide, and switch to volumetric glassware when accuracy counts.
- 4Chemical fit. Check the material stands up to the acids or solvents you plan to use.
Frequently asked questions
How does a beaker differ from a flask?
A beaker is a wide, straight-sided cylinder with a pouring lip, built for mixing, heating and moving liquids around. A flask narrows to a neck above a broader base, which suits swirling and cuts down evaporation. In short, beakers are the generalists, while flasks lean towards titration and accurate volume work. Our conical flask guide has more.
Can I measure liquids accurately in a beaker?
Not reliably. The printed marks are approximate. For a figure you can trust, use a measuring cylinder, a volumetric flask or a pipette.
Is it safe to heat a glass beaker directly?
Only if it is borosilicate, such as DURAN or Pyrex, which is made to handle thermal shock. Never apply direct heat to soda-lime glass or plastic beakers, as they may crack, soften or give off fumes.
What beaker sizes can I get?
Sizes at LabFriend span roughly 25 mL to 2,000 mL, with larger volumes available on request. Pick a size to suit both the liquid you are handling and the method you are following.
Are plastic beakers reusable?
Yes. Plastic beakers in polypropylene or PMP wash up and go again, provided you avoid direct heat and aggressive solvents that can attack the plastic.
Which beaker brands are popular in New Zealand?
New Zealand labs tend to reach for DWK DURAN, Pyrex, Kartell, ISOLAB and LLG Labware, all carried by LabFriend and shipped nationwide.
What is the right way to clean a beaker?
Give it a distilled water rinse straight after use, then a wash with mild detergent and a soft brush. Tackle stubborn residue with a lab grade cleaner, and keep abrasive pads away so you do not scratch or weaken the glass.
Is bulk pricing available?
Yes. LabFriend offers volume pricing for schools, universities, research institutes and industry. Get in touch for a tailored quote.
Do beakers include a lid?
Not as standard, though watch glasses and beaker covers can be added separately to limit contamination and slow evaporation.
How does delivery work within New Zealand?
LabFriend ships across New Zealand, with orders dispatched promptly and delivery times depending on your region. Our delivery page sets out the options.
