List of instruments used in microbiological sterilization and disinfection
Instruments used in microbiological sterilization and disinfection are as follows:[1][2][3]
Instrument list
| Instrument | Uses |
|---|---|
| Instrument sterilizers | Used to sterilize instruments in absence of an autoclave |
| Dressing drums | storage of gowns, cotton, linen, etc. |
| The microscope | used for visualising minute structures including microbes |
| Various stains | used to stain microscopic slides to get contrast |
| Hot air oven | used in sterilizing instruments for various aseptic procedures, specially if that can not be autoclaved like powders |
| Koch's or Arnold's steam sterilizer | used for steam sterilization |
| A pressure cooker | used as a portable autoclave |
| Biological and chemical indicators | Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done |
| Filters: | |
| •Candle filter: | used as household water filters and as filters for large particles in the laboratories |
| ••Diatomaceous earth filters like the Berkefeld filter | -do- |
| ••Unglazed porcelain filters like the Chamberland filter | -do- |
| •Disk filter or Seitz filter | previously used as bacteriological filters; presently obsolete |
| •Sintered glass filter | used as a good particle filter in laboratories |
| •Membrane filter and Syringe filter | used as primary bacterial/cell filters in procedures as toxin, immunoglobulin, etc. production, where the product gets denatured on heating |
| •Air filter | like HEPA filter, used in various laboratories and clean rooms to produce lamellar air flow |
| Radiation: | |
| •Gamma ray source | used in sterilization of heat-labile products like plastic or rubber syringes, catheters and gloves |
| •X-ray source | -do- |
| •Infrared light source | -do- |
| •Ultraviolet light source | -do- |
| Inspissator | used to produce culture media for bacteriology that contain egg or serum, which coagulate on heating |
| Tyndallizer | a process of sterilization from spore bearing bacteria; video link |
| 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. |
| Cardboard biomedical waste containers | |
| Reusable tubs[5] | |
| Colour coded biomedical waste bags (India) [6] | - |
| •Yellow plastic bags | for human anatomical, animal, microbiological and soiled waste |
| •Red disinfected container or plastic bags | microbiological waste, solid waste(IV tubes, catheters, etc.) |
| •Blue or White plastic bag or puncture proof containers | sharps, disposable tubing, etc. |
| •Black Plastic bag or puncture proof containers | discarded medicines, incineration ash, chemical waste |
| Disinfectants | for cleaning |
| Incinerators | to burn biomedical wastes like removed body parts, blood, gauze, linen, etc. |
