aspirator bottle use ?


I am a bit embarrassed to ask but how do you use a aspirator bottle to produce a vacuum?Correctly I mean? By aspirator bottle I am reffering to what looks like a large reagent bottle with a barbed tube near the bottom of the bottle. it Looks like i'd put a bit of tubing on the bottom barb, clamp it shut. Then fill the bottle with a suitable liquid and once full put a one hole rubber stopper on the top with a tube from the top to the flask that needs a vacuum.. but am I off or did I get it right? Like I said I feel dumb but I wanted to ask.

Could you post a Pict of what you have? I searched around, and found something different than your description.
Perhaps you are missing a part?

This link describes how to use their product...

I found lots of Picts. but little info. I suppose you knew this.
I found one bit...

http://www.usabluebook.com/p-276285-aspirator-bottle-with-ho...

Use these glass aspirator bottles for mixing, storing and dispensing reagent. Hose outlet accepts 3/8" ID tubing. Choose from 5- or 10-liter sizes. Kimax®.

Apparently from what I gathered yours is simply an aspirator bottle meant for storage or dispensing.

The first link I posted (in my previous response) is what is known as a Vacuum aspirator, and has a different use ie: gas sampling.

There is a third type that has a stop cock, and they are designed to sediment, and separate solids.

Don't take me at my word for this. I'd wait to verify it.
There is also a "contact us" or "more info" on the link you posted but I'm sure you'll get it sorted here..

You don't.

Vacuum filtration flasks are connected to a vacuum source with the side arm, while a rubber seal and Buchner funnel (with filter paper) are fitted onto the top part on the wider neck.


Vacuum sources can be a water aspirator or a vacuum pump.

http://oxfordchemserve.com/buchner-filtration-apparatus-70-m...

The flask by itself, no matter what you do with it, cannot generate significant vacuum.

Blogfast... Look at the picture of his. The barb is at the base, and would not work as a filter flask.

His is a designed different application. :) LOL!!!

A bit puzzled, to be honest.

I sure don't need one of those.

Correct,

connect flexible tubing to the bottom outlet and clamp the tubing

fill the bottle with water

put a bung in the top with a glass tube through it
connect flexible tubing from the glass tube to whatever requires a partial vacuum

release the clamp from the lower tubing

water will flow out and cause a partial vacuum

the higher the bottle is above the outlet of the lower tube
the greater the partial vacuum

bubbles of air will try to rise up the drain tube and reduce the vacuum
so put the end of the drain tube under water to prevent this.
.....................................................................................................
OR
buy a cheap vacuum pump off ebay e.g.
http://www.ebay.co.uk/itm/DC12V-80Kpa-DC-Micro-Piston-Vacuum...
which gives a partial vacuum equivalent to 8m water height
and is a lot easier to use.

Actualy you can produce vacum with that botlle. Put there water or oil and let it out it will produce vacum on botle neck.

Surely the 'vacuum' produced would be pretty much useless ?

A Slight Suck at most ?

Is it not a 'second' where the glass blower was drunk that day ?

I once toyed with those bottles thinking it might be fun to see if I could sustain a short jam jar pulsating combustion inside of a balloon without it popping from the heat. The idea was to totally surround the balloon with a layer of cooling water but I lost interest.

This aspirator bottle might be a good way for beginning chemists to pull a light vacuum.

Take a 1" PVC pipe, put a drain valve at the bottom, a and a fill cap and hose barb at the top. Fill with water, close, attach vacuum tubing to the tubulation, and open the valve to get a gentle vacuum. If need be, you can use mercury instead.:D

Do you all really believe that is the intended purpose of this bottle or is this an attempt at adapting the design? It's an honest question.

It is listed as an aspirator bottle so I imagine you would be correct. The larger the bottle, the greater the vacuum... I see 250ml - 2 liter so... I guess it makes sense.

I am of the opinion that Zombie (above) is correct to believe the caption on the item:

"Use these glass aspirator bottles for mixing, storing and dispensing reagent. "

I my view you fill it with a solution you want to dispense, attach a hose with a clamp to the port at the bottom and fill it with solution and stopper. To dispense unstopper and open the clamp.

The name "aspirator bottle" is a little odd, but may stem from the vacuum produced during dispensing, which can be stopped my restoppering.

There are a ton of aspirator bottles on line that are obviously for this purpose, with integral stopcocks:

Really no different from an Igloo water dispensing container:

Here's one of the pages I found in the earlier search... Aspirator with stop cock
http://www.marienfeld-superior.com/index.php/laboratory-bott...

"Aspirator bottles are used to sediment solid or suspended particles in liquid materials. The liquid is filled into the container. After some time, the heavier solid particles deposit at the bottom of the aspirator bottle and the stopcock is opened to release the liquid into a collection flask."

Now if the solids collect at the bottom, how do you drain the fluid thru the stopcock?


Now this one is confusing as well... Aspirator bottle glass.

PYREX® Aspirator Bottles with Hose Barb Outlet
PYREX® glass aspirator bottles are made of borosilicate glass Code 7740. Vacuum aspirator bottles have tubular sidearm outlet near the bottom for attachment of flexible plastic tubing and is very useful as a delivery/storage container for solutions. These glass as...MORE

It states "Vacuum aspirator bottles" yet there is no mention of vacuum in it's use. Perhaps this a a bottle that has no clearly defined use, and was at some point assigned an arbitrary name.

In the long run it really doesn't matter as long as you find a use that fits what you are doing but it is curious...
