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.
An Erlenmeyer flask or conical flask. A flask is a type of container made of glass. They are a common piece of apparatus used in laboratories. Their size are chosen by the volume they can hold, and is measured in metric units, like litres (L) or mililitres (mL).
In a lab, this is often done by placing the material in a freeze-drying flask and rotating the flask in a bath, called a shell freezer, which is cooled by mechanical refrigeration, dry ice in aqueous methanol, or liquid nitrogen. On a larger scale, freezing is usually done using a freeze-drying machine.
