Florence Flasks (round but with a flat bottom) , made from high quality heat resistant Borosilicate glass. Uniform thickness with a heavy beaded rim. Basically the same as the round flasks above, but the small flat bottom area allows the flask to stand upright without any support. Accurate to within 5% of rated capacity.
