packaged well which is extremely important when dealing with fragile lab glass. seems to be well made and the neck joint was a correct 24/40. overall, very satisfied--would not hesitate to buy again.
Excellent quality glass.

Excellent boiling flask. Strong and durable. The product takes a few weeks to arrive, but is well worth the wait.
order due to lab timer failing, and stir plate remaining on. The boiling flask maintained shape, and spider web cracked after the stir bar melted. No liquid came in contact with the sir plate. Excellent, and SAFE product.

This is my first round flask. Nice heft to it, measured the connection joint and found it to be exactly 24/40, with a digital caliper or as close as could be to being imperceptible. Haven't done much with it, just boiled water to check capabilities of other equipment.
Sturdy RBF

We routinely use round bottom flask in our lab and I found these RB flask to be of very good quality. It feels sturdy and does not break very easily.
Thank you.
Thank you.
A great piece of lab ware from China.

I recall when breaking glass labware meant an annoying bill from the store room manager, so I was dubious about the quality of chemical glassware coming from China for such low prices. Laboy exceeds my expectations--the glass is of a durable thickness, without ripples or "seeds" or inclusions, the ground glass mates perfectly with my American-made glassware (the grind seems a bit more coarse but to no disadvantage) and even though I haven't stress tested the flask (e.g., pouring liquid nitrogen into a flask at red heat--jeez, just kidding) I have full confidence that Laboy glassware will perform under normal lab conditions to the highest standards.
