PYREX Griffin Borosilicate Glass Beaker - Low Form Graduated Measuring Beaker with Spout Premium Scientific Glassware for Laboratories, Classrooms or Home Use - PYREX Chemistry Glassware, 1L, 2 P/k

Q: Are the markings painted on or etched in the glass?

Painted. My smallest 50ml was smudged. The lines are not crisp like my Pyrex Erlenmeyer flasks.

Q: Can anyone tell me where these beakers are made? (Which country)?

I googled Corning Pyrex in effort to find your answer. Though Pyrex is a brand of a type of glass that began in Corning, NY, it is now a global company. I found interesting information about Corning and about pyrex to much to list here. However, you may do the same and hopefully discover enough information to satisfy your needs. Also, there are phone numbers listed so you can ask them directly.

Q: Are the major graduations labeled with the corresponding volume, or do you just have to count them?

Largest 2 sizes by 100s, then 50, 20, 10 ml. (1000 ml by 100s; 600 ml by 100s; 250 ml by 50s; 100 ml by 20s; 50 ml by 10s.) So yes they are labeled for major graduations.

Q: what is the circumference measurement? need it to got on 4.72in hot plate.

Package Dimensions ‏ : ‎ 8 x 6.7 x 5.9 inches; 1.2 Pounds That's for two so half of the largest dimension will fit your hotplate.

4.7/5
