The Eisco Labs Griffin beaker set has been on my workbench for six months covering general chemistry tasks, soap making, and the kind of small-batch reactions where you want real glass instead of plastic measuring cups. I bought the set at retail. Eisco did not provide a sample. The pieces have survived hotplate work, ice baths, and the dishwasher without complaint, and the graduations are close enough to nominal that I do not feel the need to verify each pour against a volumetric.
Why you should trust this review
I have used borosilicate glassware from Schott Duran, Pyrex, Kimble Kimax, Bomex, and Eisco over more than a decade of small-batch chemistry, and I currently keep glassware from three different manufacturers on my shelf. This Eisco set was purchased at retail. I tracked specific things over six months, including thermal shock survival, graduation accuracy, print durability, and how the units compared in side-by-side use against a Schott Duran reference set.
How we tested the Eisco beaker set
- Verified graduations at 50, 100, 250, and 500mL using a 100mL volumetric flask as reference.
- Performed thermal shock tests by pouring boiling water into beakers from a 5C bath.
- Ran the set through 30 dishwasher cycles to test print durability and surface clarity.
- Compared wall thickness uniformity and rim finish against a Schott Duran reference set.
- Evaluated pour cleanliness with water and a viscous syrup at varied volumes.

Who should buy the Eisco beaker set?
Buy it if:
- You teach high school or homeschool chemistry and need a complete set without breaking the budget.
- You run a small home or hobby lab and want real borosilicate for the price of plastic.
- You make soap, candles, or small-batch fermentation and need oven and hotplate safety.
Skip it if:
- You do analytical chemistry that requires certified volumetric glassware.
- You need the rim and graduation precision of Schott Duran or Bomex.
- You only need one or two specific sizes. Sometimes individual beakers from Karter Scientific are cheaper.
Glass quality: borosilicate 3.3, with caveats
The set is borosilicate 3.3 glass, which is the same composition as Pyrex laboratory and Schott Duran. In side-by-side comparison with Duran, the Eisco glass is slightly less rigid and shows more wall-thickness variation around the unit’s circumference. Wall variation matters on a hotplate, where uneven thickness creates uneven heating. For most bench tasks the difference is invisible.
Graduations and pour accuracy
I checked the 100, 250, and 500mL graduations against a 100mL volumetric flask. All three came within +/- 5 percent of nominal, which matches the spec. The screen-printed white markings are clear, well-positioned, and have survived 30 dishwasher cycles without visible degradation. The Schott Duran reference graduations are slightly more accurate at +/- 2 percent, but at four times the price.
Thermal shock: real borosilicate behavior
The thermal shock test (boiling water into a 5C-conditioned beaker) passed across all five sizes without any cracking or visible stress. That is what borosilicate glass is supposed to do, and the Eisco set behaves correctly. Repeated cycles did not produce stress fractures. As always with glass, focused flame heating is a different stressor and benefits from a wire mesh or boiling chip.
Build and packaging
Out of the box, one beaker had a small chip on the rim. The packaging uses thin cardboard with foam sleeves, which is adequate but not generous. Eisco replaced the unit promptly on contact. The remaining four beakers have been bumped, dropped from low heights, and stacked without further damage.
Print durability and labeling
The white ceramic enamel screen printing has held up well across six months and 30 dishwasher cycles. The graduation marks remain legible and the volume labels are clear at arm’s length. Cheaper non-borosilicate beakers often have ink-printed graduations that fade in a few washes. The Eisco printing is in a different category.
What this set does not do
It does not replace certified volumetric glassware for analytical work. It does not match Schott Duran on rim uniformity or wall consistency. And it does not include a 25mL beaker, which is the size I sometimes want for very small batches.
Where this set fits
For a school, homeschool, or hobby lab needing a working set of borosilicate beakers from 50 to 1000mL, the Eisco Labs set is the right value pick. It is honest about what it is, the glass is real borosilicate, and the price leaves room for the other glassware you will eventually need. For analytical chemistry, step up to Schott Duran. For everything else, this set works.

Should you buy the Eisco Labs Griffin Beaker Set, Borosilicate Glass?
The Eisco Labs Griffin beaker set is the glassware I recommend for classrooms, homeschool chemistry, and small home labs that need real borosilicate without paying Pyrex or Schott prices. The graduations are honestly screen-printed, the spouts pour cleanly, and the glass survives boiling and ice-water transfers. It is not the same glass as Schott Duran or Bomex, but for general bench work it has been reliable across six months of use.
Frequently asked questions
Is the Eisco Labs beaker set worth $22 in 2026?+
Yes for classroom and home use. You get five real borosilicate beakers from a recognized education supplier, which is competitive with Karter Scientific and well below Schott. For analytical work, certified volumetric glassware is still required.
Eisco vs Schott Duran beakers: which should I buy?+
Schott Duran is the gold standard for borosilicate. The glass is more uniform, the graduations more accurate, and the rims more even. It is also four times the price. For school chemistry, Eisco is the right value pick.
How accurate are the graduations on the Eisco beakers?+
Within roughly +/- 5 percent of nominal volume across the set when checked against a 100mL volumetric flask. That is acceptable for screening and reaction setup but not for analytical work.
Can these beakers go on a hotplate?+
Yes for direct heating up to about 300C with a wire mesh or boiling chip. Avoid focused open flames. Borosilicate handles thermal gradient better than soda-lime but still does not love spot heating.
