These are name brand pyrex?

A worker at Corning tells me that its products can be identified by a change in its logo. If the product is labeled in upper case letters (PYREX), it is borosilicate glass. If the product is in lower case letters (pyrex), it is soda-lime glass.

What is the actual measurement of the beaker in inches (height x diameter of the mouth)?

It's just over 3.5 inches high and the inside diameter is roughly 2.5 inches (not the flared mouth, but the inside of the beaker itself).

is this item oven safe?

Yes. I use this in a pharmacy lab where it gets heated in an oven to 250 C. (482 f)

Ive used it once to heat cocoa butter and other oils for a skincare cream. It maintains the heat well and cleans up easily.

Truely heavy duty...

Heavy duty as advertised. Just wish the heavy duty was available in the tall forms. I use beakers daily...and Pyrex is hands down the best.

Perfect!!!

Heavy duty & absolutely awesome!! I wanted it to make homemade lip balm & I can even hold the top area to pour the balm because it isn't even hot!! I ordered cheaper ones from another company & they arrived broken & the company wants me to mail them back to China & then they will refund my $!!! The postage would be MORE than what I paid for them!! Best to offer better quality to begin with!
