Beakers are the workhorse of the bench: mixing, dissolving, heating, staining and temporary storage. The differences that matter are wall thickness, graduation accuracy, spout shape and whether a handle helps you move a hot vessel safely. This guide covers the sizes and options we supply in Singapore.
| Nominal volume | Typical use | Notes |
|---|---|---|
| 50 mL | Small reagent preparation | Good for staining and sample aliquots |
| 100 mL | General mixing | Common teaching and QC size |
| 150 mL | Buffer and media preparation | Handled and non-handled options |
| 250 mL | Routine bench work | Most frequently ordered size |
| 600 mL | Larger preparations | Check hotplate footprint |
| 1000 mL | Batch mixing | Use a suitably sized stir bar |
| 2000 mL | Bulk preparation | Two-person lift for hot liquid |
Thick-wall beakers resist mechanical knocks and are a good choice for shared teaching labs and heavy daily use. Standard-wall beakers heat and cool faster and are often preferred where thermal response matters. Thicker glass is not immune to thermal shock — preheat gently and avoid direct contact with a cold surface.
Beaker graduations are approximate, typically within a few percent. They are not a substitute for a graduated cylinder or volumetric flask when you need an accurate volume. Use beakers for rough volumes and transfer to the appropriate measuring glassware for analytical work.
A handled beaker improves safety when moving hot liquid, but the handle adds a stress point. Inspect the handle-to-body joint regularly. A well-formed spout reduces dripping; for viscous liquids, pour slowly and keep the spout clean.
We stock common sizes and can supply carton quantities for larger labs. If you need a specific wall thickness, handle style or graduation, send the requirement with your quantity so we can confirm the exact item rather than substitute a similar size.
No. Beaker graduations are approximate. Use a graduated cylinder for general measurement and a volumetric flask for standard solutions.
Yes, borosilicate 3.3 beakers are autoclavable. Allow them to cool gradually and inspect for cracks before each cycle.
Handled beakers are safer for hot liquids. Non-handled beakers are easier to stack and clean. Many labs keep both.
Common sizes run from 50 mL to 2000 mL. Larger vessels can be quoted on request.
Use a laboratory detergent and a soft brush; for inorganic scale, a dilute acid rinse may help. Avoid abrasive pads that scratch the glass.
