Absolutely awesome.
Shockingly high quality, especially for this price. 10-20 years ago I'd have likely paid like 4-5x as much or more at a local brick & mortar supplier for a piece like this. The frit disk level and the cylinder diameter/regularity are as close to perfect as I could ask for. Nice thick and heavy boro throughout & *excellent* joints. Exactly what I wanted, withstands plenty of external pressure and with some slow qual paper it filtered clear a particular type of solution I've been trying to clarify for like a year, in a matter of minutes. Since it's a very fast G1 I can throw whatever sort of 75mm filter paper I want on it and voila, it's medium or fine, or quant if necessary, etc. and it's a very easy and affordable size to find. I have several Stonylab pieces now including stuff like boiling flasks and they've all been so good that I don't plan to buy lab glass from any other manufacturer any time soon. As an amateur scientific glass blower of many years myself, I find such strong joints with no apparent warp or wobble in any position on so many pieces in a row is REALLY impressive; same with this super flat and level frit disk. I think I'm pretty decent, but I won't hesitate to admit that this relatively super cheap piece is probably beyond my skill level and I would laugh at anyone that asked me to make one for this price, then refer them to this listing. Should I ever break this Bchner, I'll immediately order another of the same. Thank you Stonylab, will be back, soon & often!
