Vintage Kimax Or Pyrex 250ml Erlenmeyer Flask – Made In USA, Borosilicate Glass, #26500 Or #4980

This is a vintage Erlenmeyer flask, either Kimax or Pyrex, 250ml volume.

It's used but in excellent condition – fully functional, maybe some cosmetic wear.

Made in the USA from borosilicate glass, so it's heat-resistant and durable.

The model could be 4980-250 or 26500, both classic numbers.

It's perfect for lab work – biological, dental, medical, or physical labs.

Whether you're a collector, a scientist, or just need a quality flask for projects, this one's legit.

No UPC, just good old American glassware.

It's seen some use, but it's got plenty of life left.

Grab a piece of lab history that still works like a champ.
