A thistle tube is a piece of laboratory glassware consisting of a shaft of tube, with a reservoir and funnel-like section at the top. Thistle tubes are typically used by chemists to add liquid to an existing system or apparatus.
The thistle tube shaft is designed to allow insertion through a small hole present in some stoppers, permitting the tube to be inserted into a container such as an Erlenmeyer flask.

∙ 15y agoThis is a long tube with a bulb at one end, large enough to be able to pour liquids into. It is used to introduce liquids into a flask that is usually holding a solid so that the two can react together, especially if one of the products of the reaction is a gas (eg zinc and dilute hydrochloric acid to produce zinc chloride solution and hydrogen gas). As the thistle tube is long, after introducing the liquid the level of liquid in the flask rises above the end of the tube so that it acts as a seal, so any gas evolved can be channelled out of the flask through a sidearm tube to be collected, and not back up through the thistle tube.

∙ 13y agoThistle tubes are used by scientists to add liquids into flasks carefully; they are mainly used for inserting liquid into Erlenmeyer (conical) flasks which have a stopper in them. The reservoir on the top is mainly so the liquid can be poured in easily, and the shape of such reservoir is so that liquid doesn't spill over the sides.

Function of thistle funnel?
The most usual use for a thistle funnel is to add liquid during gas preparations, for which use it is usually inserted into one hole of a two hole stopper. (The other hole contains the delivery tube.) If gas is to be delivered to the collecting vessel, you should ensure the base of the funnel tube is covered by the liquid in the flask. Inserting the thistle funnel through the stopper must be done extremely carefully, using a hollow cork borer, as the glass stem is extremely easy to snap. I would advise that this fitting is not attempted without someone to show you the correct procedure.
Why should the bottom ot the thistle tube extend beneath the surface of the hydrochloric acid?
to prevent the other reactive substance from coming into contact with the air (or whatever gas is in your flask) and force it to mix with the HCl.
