Very good.

I have purchased several funnels from Stonylab over the years. I have always found them to be a good value for the money. Whoever said the price was high has obviously never bought equipment from any top brand. I found the price to quality ratio to be amazing and surprising. The quality is very good, the funnel works well and it's durable. It is well made. This is most likely the best value funnel available. Stonylab shipped it immediately after the order and it was in my hands soon after that. I am writing this review with full gratitude and appreciation for Stonylab. Thank you. I will be a return customer again.

Nice

This flask did exactly what I needed it for, and it did not break under the around 400��c I needed to distill mercury. Furthermore, it did withstand the boiling mercury which I was slightly worried about. All in all, a worth buy and I would recommend it to anyone who needs a 500mL 3 neck.

The StonyLab 1L measure cups are very well-packed. Each cup rests in shaped foam taylored within an individual cartoon box sealed and marked fragile. The glass is crystal clear, measure marks can be seen readily and the font sizes are just perfect. Thickness of the glass is also just right giving me a feel of sturdiness. I am in Asia, a long way from the U.S. but shipping is amazingly fast. I am glad I bought the right thing from Amazon US, which would surely keep me doing that in the near future.

Love it

Nice sturdy little flasks

Just add a bit of Silicone tube and bam you have a great whip for your mighty

Holds up over time

Good quality, works well, I could wish the markings were a little clearer but thats just me maybe.

works well

Good quality and timely delivery.

I mostly use this for pouring out of containers with greased joints for vacuum applications. The pourer protect the grease from getting into the reagent.
