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, because of their use, can be divided into: Reaction flasks, which are usually spherical (i.e. round-bottom flask) and are accompanied by their necks, at the ends of which are ground glass joints to quickly and tightly connect to the rest of the apparatus (such as a reflux condenser or dropping funnel).
