Review on Laboy Glass 500ML Single Neck Round Bottom Boiling Flask Heavy Wall With 24/40 Joint Heating Reaction Receiving Flask Organic Chemistry Lab Glassware by John Snook

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.
