BASIC LABORATORY INSTRUMENTS USED IN MICROBIOLOGY

what is the meaning of Aseptic technique

• to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.

• renders an item or material safe to handle.

• A sterile surface/object is completely free of living mo and viruses.

• reduces the level of microbial contamination.

• The act of introducing mo or suspension of mo (e.g. bacteria) into a culture medium.

what is the meaning of Decontamination

• to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.

• renders an item or material safe to handle. The level of microbial contamination is reduced enough that it can be reasonably assumed free of risk of infection transmission.

• A sterile surface/object is completely free of living mo and viruses.

• reduces the level of microbial contamination.

• The act of introducing mo or suspension of mo (e.g. bacteria) into a culture medium.

what is the meaning of Sterilization

• to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.

• renders an item or material safe to handle. The level of microbial contamination is reduced enough that it can be reasonably assumed free of risk of infection transmission.

• A sterile surface/object is completely free of living mo and viruses.

• reduces the level of microbial contamination.

• The act of introducing mo or suspension of mo (e.g. bacteria) into a culture medium.

Answer explanation

Sterilization procedures kill all mo. Methods used in sterilization procedures include heat, ethylene oxide gas, hydrogen peroxide gas, plasma, ozone, and radiation.

what is the meaning of Disinfection

• to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.

• renders an item or material safe to handle. The level of microbial contamination is reduced enough that it can be reasonably assumed free of risk of infection transmission.

• A sterile surface/object is completely free of living mo and viruses.

• -Eliminates most pathogens but not necessarily all types of microbes.

  -reduces the level of microbial contamination

• The act of introducing mo or suspension of mo (e.g. bacteria) into a culture medium.

Answer explanation

Chemical disinfection does not kill spores, unlike chemical sterilization. Some common laboratory disinfectants include freshly prepared10% bleach and 70% ethanol.

what is the meaning of Inoculation

• to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.

• renders an item or material safe to handle. The level of microbial contamination is reduced enough that it can be reasonably assumed free of risk of infection transmission.

• A sterile surface/object is completely free of living mo and viruses.

• reduces the level of microbial contamination.

• The act of introducing mo or suspension of mo (e.g. bacteria) into a culture medium.

Define Analytical Balance

• The measuring pan is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.

• A pressurized chamber used for the process of sterilization and disinfection by combining three factors: time, pressure and steam

• r is a standard tool used in laboratories, named after Robert Bunsen. It is a gas-fueled single open flame.

• is a device that allows the rotation of an object about a single axis, where an outward force is applied perpendicularly to the axis.

• is a stand-alone appliance used in microbiology laboratories as a tabletop heating system.

Answer explanation

The analytical is a device used to measure the weight of materials with higher degree of precision

Define Autoclave

• The measuring pan is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.

• A pressurized chamber used for the process of sterilization and disinfection by combining three factors: time, pressure and steam

• r is a standard tool used in laboratories, named after Robert Bunsen. It is a gas-fueled single open flame.

• is a device that allows the rotation of an object about a single axis, where an outward force is applied perpendicularly to the axis.

• is a stand-alone appliance used in microbiology laboratories as a tabletop heating system.

Answer explanation

Autoclaves are mostly used for the sterilization of medical or laboratory equipment with the capacity of sterilizing many materials at once

Define Bunsen burner

• The measuring pan is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.

• A pressurized chamber used for the process of sterilization and disinfection by combining three factors: time, pressure and steam

• is a standard tool used in laboratories, named after Robert Bunsen. It is a gas-fueled single open flame.

• is a device that allows the rotation of an object about a single axis, where an outward force is applied perpendicularly to the axis.

• is a stand-alone appliance used in microbiology laboratories as a tabletop heating system.

Answer explanation

It is commonly used for processes like sterilization, combustion, and heating. In medical or microbiology laboratories, it is commonly used for micro-loop sterilization.

Define centrifuge

• The measuring pan is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.

• A pressurized chamber used for the process of sterilization and disinfection by combining three factors: time, pressure and steam

• is a standard tool used in laboratories, named after Robert Bunsen. It is a gas-fueled single open flame.

• is a device that allows the rotation of an object about a single axis, where an outward force is applied perpendicularly to the axis.

• is a stand-alone appliance used in microbiology laboratories as a tabletop heating system.

Answer explanation

The primary application of a centrifuge is the separation of particles suspended in a suspension

Define Hot plate

• The measuring pan is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation.

• A pressurized chamber used for the process of sterilization and disinfection by combining three factors: time, pressure and steam

• is a standard tool used in laboratories, named after Robert Bunsen. It is a gas-fueled single open flame.

• is a device that allows the rotation of an object about a single axis, where an outward force is applied perpendicularly to the axis.

• is a stand-alone appliance used in microbiology laboratories as a tabletop heating system.

Answer explanation

In a laboratory, hot plates are used to heat glassware and their components.
