Most water baths have a digital or an analogue interface to allow users to set a desired temperature, but some water baths have their temperature controlled by a current passing through a reader. Uses include warming of reagents, melting of substrates, determination of boiling point, or incubation of cell cultures. It is also used to enable ...
Water bath: to heat things uniformly from all sides at a set temperature up to the boiling point of water Needle Destroyer: Burns the needle electrically either cuts the syringe manually or burns it electrically Sharps container [4] A imperforable container for sharp wastes like needles, blades, microscope slides, broken glass, etc.
A boiling tube is a large test tube intended specifically for boiling liquids. A test tube filled with water and upturned into a water-filled beaker is often used to capture gases, e.g. in electrolysis demonstrations. A test tube with a stopper is often used for temporary storage of chemical or biological samples.
A variation on this theme is the water bath in which the sand is replaced with water. It can be used to keep a reaction vessel at the temperature of boiling water until all water is evaporated (see Standard enthalpy change of vaporization). Sand baths are one of the oldest known pieces of laboratory equipment, having been used by the alchemists.
A heated bath is used in the laboratory to allow a chemical reaction to occur at an elevated temperature. [1] In contrast to traditional Bunsen burners, heated baths use liquids to transfer heat to the reaction vessel. This is achieved using a high-boiling point liquid inside a thermally conducting bath (usually made of metal).
Water-cooled condensers are suitable for liquids with boiling points well above 0 °C, and can easily condense vapours with boiling points much higher than that of the water. Other cooling fluids may be used instead of water. Air with forced circulation can be effective enough for situations with high boiling point and low condensation rate.
Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis. [3] Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the ...
A Florence flask/boiling flask is a type of flask used as an item of laboratory glassware and is named after the city Florence. [1] It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat botto
