First Buchner funnel, Can I use it with a Boro 3.3 boiling flask as my Solvent catch without using Vacuum grease since It's a weak filtration Vacuum pump safely with little chance of the glass joint seizing? Or am I asking for trouble without using a thick walled Erlenmeyer flask &Vacuum grease?

Thermos or Vacuum flask

Would be nice if the devs could add a thermos or vacuum flask. You could put your hot drinks there and they stay hot for longer. It's a reasonably common item to find in any household so it would be realistic, and it won't give a significant edge to the player anyways just create more opportunities and options. If they allow these to spawn in Loper that would really open up possibilities.

looking for some insight to aluminum vacuum lost wax casting. some larger parts crack like this. this was cast in a 5 inch perforated flask at 900f. AL 6061 temp was 1450f. it sat for about 15 mins before dunking. should i let it cool more before dunking and just deal with extra work of cleaning?

TIL genericization is when a company or product's name becomes synonymous with the entire category. Like Xerox (a US company) became synonymous with photocopying, Maggi became synonymous with noodles and Thermos became synonymous with vacuum-sealed flasks. finshots.in/markets/the-t…

Is it safe to heat water (with food) inside a stainless steel vacuum insulated flask with an immersion water heater rod?

Illustration The idea is to passively cook stuff in a small thermos food jar by taking advantage of the trapped heat. These flasks typically market 18/8 or SU304 stainless steel construction and some sort of vacuum insulation method within their double or triple layer walls to preserve the temperatures of the contents inside over longer periods irrespective of the outside temperature.

I'm not sure how the water heating immersion rod actually works... If I googled it correctly, there is a cooper wire running inside the rod structure through which current is passing when plugged on an AC outlet. The current heats up the wire, which heats up the inner air chamber, which heats up the metal rod... is this basically correct?

  1. From an electrical point of view, is it safe to do what is shown in the video or is there a risk of electrical shock by touching the metal thermos flask? I don't really understand the electrical aspect of it and have been reading conflicting information. I noticed he kept his hands of the thermos flask while the heating rod was heating up the water inside...

  2. In principle, I would have assumed that one wouldn't have to worry about the thermos being too hot to the touch since the inner and outer walls of the flask are not supposed to be thermally coupled (right?)... But after inspecting some closeup pictures I've found online, it kind of looks like the whole stainless steel structure of this specific flask is actually a single piece... then how on hell could the thermal insulation work the way it does in the first place?? Maybe it's not really one single piece and the seams are just very very hard to tell... or maybe the lid of the container needs to be put on for the thermal insulation to work somehow?

I don't know what to think. Hope it's not an inappropriate question for this sub.

Appreciate any info because I'd like to cook myself some yumy by this hassle-free method too.
