Fire TV is Amazon's answer to the Apple TV, and to other options like the Roku 3 and the Google Chromecast. Fire TV brings Amazon Instant Video, Showtime Anytime, and tons of games to your big screen TV.he Amazon Fire TV seems pretty cool, but it seems like you really need to purchase Amazon Prime to make it worthwhile. (Netflix is on both, so that's a wash.). But for me, the biggest draw of Apple TV is AirPlay.
An evaporating dish or watch glass is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids,[note 1] and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents - most commonly water - to produce a concentrated solution or a solid precipitate of the dissolved substance. Most are made of porcelain or borosilicate glass. Shallow glass evaporating dishes are commonly termed watch glasses, since they resemble the front window of a pocket watch.
1 Storing the petri dishes in the refrigerator prevents the water inside the dishes from evaporating (bacteria need a moist environment to grow). 2  It also allows the surface of the agar to harden slightly, which prevents any tearing or gouging when you transfer your bacteria samples. In a heat proof dish or bowl, stir half a teaspoon of the nutrient agar powder into 60 ml (approximately 1/4 cup) of hot water. 2  Multiply these quantities for however many petri dishes you plan on using.
