Symptoms of Hip Pain. Sometimes pain from other areas of the body, such as the back or groin (from a hernia), can radiate to the hip. You might notice that your pain gets worse with activity, especially if it's caused by arthritis. Along with the pain, you might have reduced range of motion.
At the opening(s) at top of the neck of some glass flasks such as round-bottom flasks, retorts, or sometimes volumetric flasks, there are outer (or female) tapered (conical) ground glass joints. Some flasks, especially volumetric flasks, come with a stopper or cap for capping the opening at the top of the neck.
Flasks are used to contain substances. They are usually made of glass or borosilicate glass (Pyrex). They can be used to heat the substance inside of them. There are many different types of laboratory flasks. They differ in their shape and what they are used for.
