Your cart is empty. This is the perfect mug for a scientist, nerd, geek, teacher, parent, or gifted student... actually... pretty much everyone. When coffee or any other dark-colored drink is added, the graduations become even more visible. Whether you are enjoying a cup of espresso in the AM or some liquor on the rocks in the PM, you're going to be satisfied.
500mL capacity.
There are other flask mugs. We tried them all. Some of them may even be, GASP, less expensive. But this is the one you want. It is lab quality (seriously) and will last. Microwave safe.
Note: Wash thoroughly before use.
This mug measures 3.75" tall, has a top diameter of 2.7", a base diameter of 4" and is 5.5" wide including the handle.

La taza llegó en buenas condiciones, es un poco difícil de sujetar, si la tocas por otra parte que no sea la manija te vas a quemar, se siente muy ligera.

This is as fun as an Erlenmeyer coffee mug gets! Without the tall tube opening. So it works great for my coffee and tea. It is a bit thinner than I had thought, including the handle. But the glass is good glass so with some attention it will be great fun for showing off. And now, with C-19, I show off on Zoom! The flip side of "thinner" is that it is not a bulky, thick, look, but much more coffee on the deck look. Thanks!!! 😃😃🚂

There's something amiss with the shape of this mug that makes it very difficult to drink out of. I thought it would be fine and look neat. After spilling multiple times, turns out this is just a neat looking pen holder on my desk.

Quite the conversation starter. Took to training session and left to hold my seat. Looks of great questions on it.

I've gone through a few variations of these erlenmeyer flask mugs in the past made with thinner-walled glass, and they've broken fairly easily (I question if they were actually borosilicate glass). This one has thicker glass walls and feels more substantial. I'm happy with it so far!

Just what you expect! Looks a little smaller in person but considering it's bottom-heavy and only holds just over 500mL, that's just the visual effect. Measured it, and it's true in volume measurement too! Just wish the handle was a bit easier to hold in shape.

My fiancé worked with borsilicate glass and loved this mug for his birthday. First thing he did was assess the accuracy of the measurements, it falls short in that department but that was not my concern at all! He's gotten compliments at work on it, specialty since it has a handle and can't be confused for a real beaker.. Which apparently has happened before...

This is the culmination of everything I could hope for in a beverage container, excluding those meant for travel or sports.It's lightweight, non-porous (easy to clean) and has a BIG, FLAT BASE. If you're anything like me, you've absent-mindedly contributed liters upon liters of fluid into various styles of flooring. Not intentionally, but because you were distracted while reading or playing games. Perhaps your eyes are focused on the happenings of a classic science fiction novel or bloodbath of a fantasy tale. You send an arm out into the void to look for something. Splat. Maybe you adjust yourself on the couch. Splat.I have not spilled anything recently. Not because my awareness of my surroundings has increased, but thanks to this repurposed lab-ware. It's an excellent gift for someone you like, or yourself.
