The glass tube with corks is often used by laboratories, but the test tube with cork stopper or others is also used to contain some spices like vanilla pods so they can retain all their flavor and aroma. Some glass tubes with corks are also pure decorative objects to display sand, sweets or cosmetics.
Test tubes with corks are primarily aimed at analytical laboratories, which use them as test tubes for certain solutions or for blood sampling. The wider glass tubes with a cork stopper can be used for decoration, for certain food products (for example packaging of vanilla pods) or to display sweets such as dragees (sugar almonds) for a wedding or baptism.
A glass tube with a cork stopper offers many benefits. It does not denature the product that is enclosed in its interior while allowing to see it. A glass tube with a cork stopper is also ideal for storing small quantities, and some can even be heated. If spices are stored in these glass tubes, all their scents and flavors remain intact for a very long time.
Some situations require glass tubes with a cork. Generally speaking, they are necessary to transport anything liquid or volatile. Thus, laboratories, cosmetics and some food products manufacturers only use tubes with corks.
Several solutions are available for an optimal closure of the glass tubes. One of them, and surely the most effective, is the glass tube with cork since it fits very well and its expansion is perfect. A screw caps may also be used in some cases. Finally, plastic caps are designed specifically for use in medical analysis laboratories.
