3 Glass Boiling Flasks Flat Bottom 250- 500-1000mL

 

Offered for sale are 3 popular sizes of boiling flasks. Boiling flasks are nice to use because they they heat more evenly than a beaker or Erlenmeyer flask. They had fallen out of favor to use because they had rounded bottoms, but these have the flat bottoms which makes them much better to use. They are made of borosilicate glass (heat resistant). With this auction, you receive a 250mL, 500mL, and 1000mL. The 250mL is 5.5 tall and uses a size 6 rubber stopper. The 500mL is 6.75 tall and uses a size 6.5 rubber stopper. The 1000mL is 8.25 tall and uses a size 8 rubber stopper. We are also selling these with stoppers. " " "
