In microbiological practices, constant shaking allows liquid-grown cell cultures grown to constantly mix with the air. Some key benefits of shaking water bath are user-friendly operation via keypad, convenient bath drains, adjustable shaking frequencies, bright LED-display, optional lift-up bath cover, power switch integrated in keypad and ...
A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point. The vapor is then cooled as it goes through the inner tube of the condenser. There it becomes liquid again, and drips into the smaller collecting flask at right, immersed in a cooling bath. The two hoses connected to the condenser circulate water ...
A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C. These low temperatures are used to collect liquids after distillation , to remove solvents using a rotary evaporator , or to perform a chemical reaction below room temperature ...
To heat an object, it is placed within the basket of the heating mantle. In further contrast to other methods of applying heat to a flask, such as an oil bath or water bath, using a heating mantle generates no liquid residue to drip off the flask. Also, heating mantles generally distribute heat evenly over the surface of the flask and exhibit ...
In a direct-contact condenser, hot vapor and cool liquid are introduced into a vessel and allowed to mix directly, rather than being separated by a barrier such as the wall of a heat exchanger tube. The vapor gives up its latent heat and condenses to a liquid, while the liquid absorbs this heat and undergoes a temperature rise. The entering ...
The hot vapor of some liquid is introduced at the upper end of the inner tube, and condenses in contact with its colder walls. Water (or some other fluid) is constantly circulated in the jacket to carry away the heat of vaporization released by the condensing vapor, keeping the tube below the liquid's boiling point. The condensed liquid drips ...
