Pyrex Glass Griffin Beaker, Low Form, Measuring, 1,000 mL

Quality was excellent. Glass is thickness is exceptional.

After breaking several pieces of (allegedly) borosilicate glass cookware -- in spite of being extremely careful and always using a heat diffuser between the flame and glass -- I decided to resort to pyrex lab glass for the preparation of herbal medicines and my morning masala chai (metal cookware alters the natural medicinal compounds in many herbs and tea, hence glass is most desirable). That makes this the most important piece of cookware I own, oddly enough. Anyway, this pyrex beaker does the job just fine so far and will hopefully be something I replace quarterly or semi-yearly, rather than semi-weekly. :)It does seem to be of reasonably solid construction, thicker glass than the borosilicate tea pots and cookware I've tried. The white markings are nice and clear without having to press your nose up to it and the pour spout is well-formed. So far so good.UPDATE: Here it is one month later and this beaker is holding up just fine. I always use it on a flame diffuser on the burner of a gas range, to prepare a medicinal masala tea twice per day. Sometimes when pressed for time I've used a medium-high flame, yet so far no ill effects.I'm satisfied that this makes better glass cookware than the borosilicate glass cookware sold for consumer use.ANOTHER UPDATE: It's now over three months later (June 21, 2011) and this same pyrex beaker is still brewing my tea and herbs, sitting on a flame diffuser on my gas stove at least twice a day every day without fail -- sometimes with the flame turned up quite high, too. Three months is actually a record for glass cookware longevity in this house, so this was a great buy!6 MONTH UPDATE: Yes, it's still in one piece and doing the job everyday after 6 months. Raised the rating to 5 stars, as 6 months of at least twice-daily use is fairly impressive and far exceeds the durability of the others I've tried. This is a great product and well worth the price.

I use this in the kitchen for various things and it's super handy! Being heat-shock resistant means it can be used to replace a number of other tools in my small apartment and free up space, which is always helpful. I use it to mix up and pour 'Better Than Bouillon' through a strainer to get the cartilage bits out, soak dried mushrooms in boiling water, brew batches of tea or coffee concentrate, rinse shirataki noodles, among other things. The pour spout is very handy, and it's large enough to make a good amount of anything but small enough that it is super easy to wash by hand. I have even put it directly on a burner to heat things up, though that does make me nervous... I've whacked it pretty hard on ceramic and stainless steel and it hasn't broken or chipped. Borosilicate glass is the great, it's a shame that it is being used less often in cookware. Anyways, handy little thing! Get yourself one!

Excellent value. High quality.

very nice, just what i wanted

I admit this is a bit knit picky, but there is a slight snag on the inside of the beaker. Like a grain of sand that wasn’t melted in the manufacturing process. It doesn’t effect the glassware’s use for my purposes but I inevitably spend an extra few seconds scrubbing every time I was thinking it’s debris until I remember that it’s there.

Will be purchasing more from this seller again.

Solid glass. Perfect size for mixing components. You can use your hand held immersion blender right inside this beaker.I love it!

Used from -40 to 300 Celsius (-40 to 550 Fahrenheit). Solid Pyrex beaker.
