How much space does the flask take up? Can you tell me how wide the base is?

What is the diameter of the Büchner funnel at 200mm in this flask. In addition to that, what is the barb size of the hose that it takes, or how big is the hose that it takes?

As I see it, the "lid" or opening requires It has a top diameter of 46mm and a rubber stopper with a diameter of 5. I believe that 12 diameter tubing is the correct size

The range is up to

Is it necessary to use a #10 stopper with this flask?

A #10 is too large according to our tests. I have been dealing with the #9 for about 15mm into the neck and 10mm above at the top. Let us know if there is anything else we can do to help.

Selected User Reviews For United Scientific FG5340-2000 Borosilicate Glass Heavy Wall Filtering Flask, Bolt Neck with Tubulation, 2000ml Capacity (Fivе Расk)

The Jetted Erlenmeyer Flask is a high quality 2L It's great to have this Walls are solid and 1/2 of the bars are barbed

5/5

The vessel I have was made in India, and it appears to be of the highest quality borosilicate glass in perfect condition with a smooth, round mouth. The stopper has five stops. In my experience, the flask can withstand 30 inHg vacuum without any issues. When using a 600ml ceramic Büchner funnel, I can pull up to 25 inHg vacuum, and so can I recommend it!.

The product provides good extraction under a vacuum of 25 hg

5/5

Currently, it is working well for me in terms of extraction. Using it with 25Hg vacuum, it’s working well. The glass is thicker than I thought, but it still seems to be working properly.

There was no connection to Barb

4/5

I have a flask that measures 5". It was just this evening that I received the flask. In good condition, it arrived. From what I read in another review, I thought a 3/8" barb connection would be used. There are 539 characters in this number. By the way, the 3/8" barbs on my other equipment have a diameter of 0 mm. The hardware store will have to come up with an adapter and a new hose for the job, so it's not a big deal. There is no need to worry about the #9 stoppers working.

The material is heavy duty, and the size is large enough

5/5

This filter cup is for use with a 600ml top filter. It works fine, as long as you have a 1/2 barb for the tube. A thick material. The material is heavy duty, and the size is large enough.

This seems solid, but its 1/2" barb (not 3/8") made it difficult to use

3/5

There seems to be no problem here and it appears to be solid- The barb diameter of the made gadget was 1/2", while the size of all the others is 3/8", so I had to return it because it was incompatible without.

It is useless

3/5

There is so much unevenness in the filter that it really looks like it was made by someone by hand, so hard to squeeze the filters together. We are disappointed with the results.
