A filter flask (sometimes called a Büchner or vacuum flask, suction flask, or even side-arm flask) is a piece of laboratory glassware with an attached hose barb for connecting a flexible hose/tubing or a vacuum pump/filtration pump for vacuum filtration.
What does a filter flask look like?
The filter flask looks like an Erlenmeyer flask with a short arm coming out of it. The “arm” is designed to connect the flask to a vacuum source. When sealed on the top with a stopper or a Buchner funnel, the vacuum flask will hold a reduced pressure.
What is the side arm of a filter flask for?
The borosilicate glass conical filtering flask with integral side arm is ideal for storage, mixing, and transferring of various solutions.
Can a side arm flask be used for vacuum filtration?
These side-arm flasks are designed for use in vacuum filtration procedures with classic Millipore Glass Filter Holders.
Why is a Büchner funnel used?
A Buchner Funnel is a fritted/perforated funnel used in commercial laboratories for the vacuum-assisted filtration and separation of liquid substances. Buchner Funnels allow you to filter liquids by pulling them through qualitative filter paper and perforations in the top of the funnel using a vacuum pump.
How do you set up vacuum filtration?
To perform a vacuum filtration, clamp the flask securely to a ring stand. Add a Buchner funnel with a rubber funnel adaptor. Obtain a piece of filter paper in the funnel that is small enough to remain flat but large enough to cover all of the holes in the filter.
What is a filter funnel?
A filter funnel is a laboratory funnel used for separating solids from liquids via the laboratory process of filtering. In order to achieve this, a cone-like shaped piece of filter paper is usually folded into a cone and placed within the funnel. The suspension of solid and liquid is then poured through the funnel.
What is glass funnel?
A separatory funnel, , separation funnel, separating funnel, or colloquially funnel, is a laboratory glassware used in liquid-to -liquid abstraction to dispersed components of liquid mixture into 2 immiscible solvent of different thicknesses such as Oil and Water.
Is a pistol a sidearm?
A sidearm is a weapon, usually a handgun, but sometimes a knife, dagger, sword, bayonet, or other melee weapon, which is worn on the body in a holster (in the case of a pistol or revolver) or sheath (in the case of a knife, dagger, sword, or bayonet) to permit immediate access and use.
What equipment is needed for vacuum filtration?
The suspension passes through filter paper of a known pore size which retains the bacteria or particles. The filtration equipment used for this procedure consists of an oil-free vacuum pump, filter apparatus, filter flask and often a filtration manifold.
What does a volumetric flask look like?
These flasks are usually pear-shaped, with a flat bottom, and made of glass or plastic. The flask’s mouth is either furnished with a plastic snap/screw cap or fitted with a joint to accommodate a PTFE or glass stopper. The neck of volumetric flasks is elongated and narrow with an etched ring graduation marking.
How does a water aspirator work?
A water aspirator works when water from the tap is forced at a high velocity through a small nozzle. At the smallest part of the nozzle, a vacuum is created. A tube attaches to this portion and the vacuum draws fluid up through that tube.
