My first Master put it out when I drank a jar of beer, and refilled in a manner which displeased him.

We were notified that the hospital directors in the Gaza Strip got together on 16 April and decided to stop all elective operations due to the lack of oxygen until the tanks were refilled.

At the end of April 1994, there was also a problem with the supply of oxygen in the Gaza Strip since the trucks that carry the empty oxygen tanks to be refilled in Israel were not allowed to enter.

Burets are used to titrate liquids. A buret is filled with a specific volume of a liquid, and placed beneath it is a container such as an Erlenmeyer flask. By opening the valve on the buret, the liquid in the container will then be titrated. High quality burets have a venting mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated.
