If you are asking about the glass measuring beaker Yes they are food safe glass

How much heat can these beakers handle, please (I noticed it says heat resistant)?

I'd be afraid to put heat to them. They are not tempered...might shatter.

what is the highest temperature these can withstand?

Borosilicate glass will begin softening above 800C (~1500F). Any temperature below this should be a good operating temperature but it should be understood that at these higher temperatures that very rapid cooling or heating either one could result in the glass breaking mainly due to temperature difference within the glass. Borosilicate 3.3 is more resistant to these stresses than other types of Pyrex glass. Dennis Brunsell TN Lab Supply
