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.
The Schlenk flask and the Straus flask are another two that look fairly similar. Schlenk flasks are commonly used in air-sensitive chemistry, as the side arm allows an inert gas such as nitrogen to be pumped into the vessel. The Straus flask, on the other hand, is used to store dried solvents.
