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.
Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...
Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.
Sterilization of an inoculation needle via alcohol burner. The inoculation needle is sterilized using the aseptic technique. [1] [2] [3] [7] An open flame from an incinerator, a bunsen burner, or an alcohol burner is used to flame along the tip and the length of the needle that is to be in contact with the inoculum (or the propagule).
Ethyl rubbing alcohol has an extremely bitter taste from additives. The specific gravity of Formula 23-H is between 0.8691 and 0.8771 at 15.56 °C (60.01 °F). Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water.
Dishwasher salt is a particular grade of granulated, crystalline sodium chloride intended for regenerating the water softener circuit of household or industrial dishwashers. Analogous to water softener salt, dishwasher salt regenerates ion exchange resins , expelling the therein trapped calcium and magnesium ions that characterize hard water .
A hypodermic needle is used for rapid delivery of liquids, or when the injected substance cannot be ingested, either because it would not be absorbed (as with insulin), or because it would harm the liver. It is also useful to deliver certain medications that cannot be delivered orally due to vomiting.
Rubbing alcohol as far as I know is applied in two ways: 1, since concentrated alcohol is a disinfectant (it kills most microorganisms on contact), it can be used to wipe a portion of the skin to remove (that is to kill) any potentially infectious bacteria from it, eg.: like before applying the needle for an injection or taking blood; 2, since ...
