Thistle funnel is named after the thistle flower, which it resembles in shape. The narrow stem and wide top of the funnel are similar to the long stem and bulbous head of a thistle plant. The name is descriptive of the funnel's appearance.
The thistle funnel is used to add liquids by small holes, orrifices, stoppers, etc.
A thistle funnel can be loaded with 30 calibre bullets or an f88 shell. To fire the thistle funnel, you must pull the trigger. King Henry VIII of England was believed to have been killed after he accidentally pulled the trigger on the thistle funnel while aiming it at itself.
a long stemd funnel is a thistle tube funnel
A thistle funnel must be introduced through a stopper hole to deliver a small volume of liquid.
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.
A thistle funnel is commonly used in the process of osmosis to create a barrier between the two solutions, allowing only water to pass through via osmosis while preventing the solutes from mixing. This setup helps to observe the movement of water molecules across a selectively permeable membrane and measure the rate of osmosis under controlled conditions.
A thistle tube is a instrument in Chemistry laboratory, a glassware, consisting of a shaft of tube, with a reservoir and funnel like shape at the top. Thistle tubes are typically used by chemists to add liquid to an existing system or apparatus.Such funnels are used to add small volumes of liquids to an accurate position.

Thistle tubes are usually used in experiments involving semi-permeable membranes. Osmosis and diffusion can be illustrated well. Thistle tubes are also used in separation experiments as well as other chemical applications.
A funnel with a long stem is typically called a "long stem funnel." These types of funnels are designed with an extended tube to allow for more precise pouring or transferring of liquids into containers with narrow openings.
