Christmas ideas + A beautiful flask + Questions

Yttrium2 - 25-12-2019 at 13:22

Im wanting to get the best gifts, so far I've got green tea, ginko biloba, Ticonderoga pencils, socks, slimfast, protein powder, turkey tail mushrooms capsules, acne pick, and Neutrogena eye gel cream... Not sure what to get exactly, I've got a $200 limit... Thinking of removing the last two items... Probably should stop smoking tobacco as im at it, because after all the greatest gift is one's own presence. Now, *cough*...



This here is a beautiful flask, by the looks of it, the only problem (I think) is that it's flat bottomed. Because it's flat bottomed, it's more likely to break from mechanical and thermal shock correct?

Lastly, if one were careful, could they do distill distillations and reactions in a 100mL graduated cylinder? --it seems that this would be beneficial because one could see how much fluid has been removed by looking at the volumetric measurements as the liquid comes off.


I am wanting to get a single piece of chemistry gear to inspire me, something like a paper weight I can have on my desk that will bring joy but also serve a dual purpose. Was looking at the Corning flask admiring it's beauty but it's flat bottomed, perhaps an erlenmeyer would be better. I'll later get a glass tube and stopper so I can do distillations. Or should I get a Retort!?


Any suggestions as for gifts, I'd like stuff that serves several purposes or has a lot of utility.




P.s. the presto 23 quart canner is on sale.



Thank you for your time,
And sorry for making another thread,
To whom it may concern

So long as the graduated cylinder is borosilicate shouldn't have issues running reactions out of the flask. I've heated graduates before in a hot water bath, because of the shape it would be tenuous to attempt to heat them on a hotplate or the like. Way back when I did distillations out of volumetric flasks on their sides. More often I've seen people collect products from distillations in graduate cylinders.

This might be it

Suggestions?

Yttrium2 - 25-12-2019 at 16:55

I went with this instead

Hopefully it was a wise choice to vouch for this as my only piece of lab equipment over the graduated cylinder.

Someone on Amazon said that the stopper leaks, is there a good way of ensuring a snug fit with the rubber stopper without stressing the glassware?
Is Vaseline the solution or what?

Any idea what stopper size that 100mL grad cylinder needs

Yttrium2 - 4-1-2020 at 23:11

Well I went with a test tube rack, test tubes, powder scoop, brush, test tube clamp..


I am wondering what other piece of labware I should get to compliment what I've got so far. I was thinking of something for distillation. Wanting to get some sort of flask, I hear erlenemeyers can crack, what about the flat bottomed flasks?


Recommendations? I've got 21$ Amazon to spend

Where have you heard erlinmeyers crack? Dont get a flat bottom for distillation unless you dont have another option.

I've heard that the edges make them more prone to cracking from the expansion and contraction of the glass. I've heard they are not rated for more than 121C

Now back to my question, what would be a good compliment to the test tubes and rack? I was thinking of this

But the whole thing about the erlenemeyers cracking makes me weary.

Also, I could piece together a kit for even cheaper from eBay.

Wanting something simple for distillation...

Probably should go with a stoppered Erlenmeyer with a borosilicate tube coming from it.

As many people have said, please stop asking questions like this.
Go read some books, watch chemistry youtube videos, and just look at pictures of glassware.
