Product review

This set contains three 33.8 oz (1000 ml) Erlenmeyer flasks supplied in a single box.

Each flask is formed from 3.3 borosilicate glass — the highest-grade inert laboratory glass — providing good resistance to thermal shock and many chemicals. The flasks feature a narrow mouth with printed graduation marks, a shaped pouring spout, a reinforced rim and a prominent marking spot for labels or notes. Walls are manufactured to a uniform thickness for added durability.

Intended for stirring, mixing and heating of liquids in laboratory and everyday contexts, these flasks comply with ASTM Specification E960 (meeting Type I requirements) and align with ISO 3819 for laboratory glassware. They are suitable for general lab procedures and hobby uses, but are not calibrated instruments for precise volume determinations.

If any of the flasks arrive damaged during shipping, please contact the seller to request a refund or replacement. For questions or further assistance, customer support is available and will respond promptly.

Pros

  • Made from high-grade 3.3 borosilicate glass
  • Printed graduations and large marking area
  • Sturdy construction with uniform wall thickness

Cons

  • Not intended for precision volume measurements
  • Packaging may allow breakage in transit
  • Narrow mouth limits pouring of viscous liquids

VerdictThese 1000 ml Erlenmeyer flasks deliver laboratory-grade glass in an economical three-pack. Constructed from 3.3 borosilicate, they offer chemical resistance and thermal stability, with molded graduations and a narrow mouth for controlled pouring. They’re sturdy for mixing, heating and routine lab or hobby work, though not intended for precision volumetric measurement. Packaging can be improved, b

Reviews

  1. Dean c 5/5

    Sturdy flask

    Very high quality.

  2. N. Kiel 5/5

    Sturdy and great value

    We used them for potion-making at my son's Harry Potter party. Children aged 3 to 10 handled the flasks and they held up well through the activities. Also ideal for science-themed events.

  3. RB 5/5

    Perfect for rinsing brushes

    I started painting with acrylics again and these are excellent for holding and rinsing brushes between colors.

  4. G. N. Taylor 4/5

    Packaging could improve

    One set arrived broken in the box. Aside from the shipping damage, the flasks worked fine.
