Florence flasks sizes 100-2000ml; save up to 60% on bulk flask & stopper bundles.
Boil, bottle, decant; use as flower vases or terrariums for display, gifts, weddings!
Our heavy duty Florence (boiling) flasks are made from heat resistant borosilicate glass (Pyrex) for lab use but look great as floor or hanging terrariums.
Markings are limited so they can also be used for packaging or for display in store windows or at trade shows.
Florence flasks have thicker walls than other flasks and make them suitable for vigorous boiling; hence their alternate name "boiling flask".
Florence flasks can be used interchangeably with Erlenmeyer flasks if all you want is a decanter for wine or juices.
They also make attractive terrariums, especially the larger sizes.

No Glassware Returns
Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package.Call first if you are unsure of what you need.
If the item is clearly defective, either heavily bubbled, chipped or with really bad markings, send us an image & we will refund you.
